HP Color LaserJet 9500 MFP
•
HP Color LaserJet CM3530 MFP
•
HP Color LaserJet CM6030 MFP
•
HP Color LaserJet CM6040 MFP
All of these models are called MFPs hereafter. This checklist is written for acceptance by the
National Institute of Standards and Technology (NIST), and it will be available at the NIST
Checklist website. HP thanks NIST for its support in the process of creating this document.
This checklist is meant for trained network administrators who use HP Web Jetadmin version 10.1
or above in enterprise networks. It includes step-by-step instructions to configure one or more MFPs
on a network.
This checklist assumes that network administrators are familiar with HP Web Jetadmin and
management of HP MFPs and printers. Network administrators should be familiar with the MFP
Embedded Web Server (EWS), HP Jetdirect, and firmware upgrades for Jetdirect and MFPs. Refer
to the MFP User Guides and the HP Jetdirect Administrator Guide for more information. You can
find these documents and more information by searching for it at hp.com.
HP Web Jetadmin is the recommended management tool for all HP network printing and digital
sending products. It handles all settings recommended for best security in this document and much
more. It is available free for download and installation at the following location:
http://www.hp.com/go/webjetadmin
You can also find HP Web Jetadmin by searching for it at hp.com.
This checklist applies to most types of networks; however, it is developed and tested in the
following environment:
•
An ordinary TCP/IP network
•
Microsoft Internet Explorer version 6.0 with SP2
Chapter 1
HP LaserJet and Color LaserJet MFP Security Checklist
1
•
HP Web Jetadmin Version 10.2 installed on a Windows XP or Windows Vista PC
•
One of each supported MFP with the latest updated firmware found at hp.com
The process for configuring this checklist is developed using HP Web Jetadmin to manage all of the
MFPs at the same time.
This checklist covers only those parts of HP Web Jetadmin that pertain to appropriate security
settings. See the user guides, admin guides, and help files for information on other configurations.
Cautions
HP is dedicated to providing the best and latest security information available for MFPs. This
checklist is meant to help you to improve MFP security in your workplace. HP has tested this
checklist to ensure that MFPs continue to provide the best possible performance while averting
possible security threats; however, some of these settings can cause unexpected problems in your
environment. Please be aware of the following cautions before you begin:
Follow the Checklist in Order
The settings in this checklist are presented in a specific order to ensure success. Many of these
security settings can be configured successfully only in the correct order. You should follow the
instructions in this checklist exactly and avoid making additional configurations during this process.
Other settings can disrupt the order and cause unexpected results.
Understand the Ramifications
HP Web Jetadmin and MFPs include a wide variety of useful settings designed to make work easier
and more productive. However, raising the level of security may require sacrifices in these areas.
Be aware that applying this checklist will limit or even eliminate some of these features. See the
Ramifications chapter for more information.
HP provides this checklist as a guide to best-practice security configurations that allow for
reasonable convenience and usability. Some of the recommended settings create extra steps when
accessing and managing MFPs. For instance, once you disable EWS configuration, you cannot
access it again until you re-enable EWS configuration from HP Web Jetadmin.
These settings are tested in a variety of conditions and using various combinations of simulated
customer environments. Testing includes configuring all of the MFPs at the same time and verifying
that the affected features continue to function. However, it is impossible to test these configurations
in all possible network environments. You should test these settings in your environment to ensure
that you understand their effects. You may find that some of the settings cause undesirable
limitations. See the Ramifications section for further information and cautions.
Continue to be Vigilant
This checklist is provided only as a complementary guide to known best practices for increasing
MFP security. HP does not claim or warrant that these configurations prevent misuse of MFPs or
networks or that they prevent malicious attacks on MFPs or networks. Use this document at your
own risk.

MFP Environment
NIST defines several types of user environments, many of which are compatible with HP LaserJet
and Color LaserJet MFPs. However, this checklist is written for MFPs in an enterprise environment or
a small to medium business environment. These environments use most of the network features
available with MFPs. This entire checklist can be configured using HP Web Jetadmin. You should
configure as much of this checklist as possible while adapting the settings to your specific situation.
Assumptions
This checklist makes some assumptions about network administrators and about enterprise
environments:
•
Network administrators: This checklist assumes that readers are trained network
administrators who are familiar with common networking practices such as configuring HP
Jetdirect connections and using HP Web Jetadmin. Administrators should have read the
MFP user guide, the MFP administrator guide, the Jetdirect administrator guide, Web
Jetadmin user guides, and help files. This checklist relies on these materials for necessary
information. All of these guides are available by searching for them at hp.com.
•
MFPs: This checklist covers security settings for specific HP LaserJet MFPs and HP Color
LaserJet MFPs. It is meant to enable you to configure multiple MFPs simultaneously. It
assumes that the MFPs are turned on, connected to the network, and in the factory default
state.
Most of the settings recommended in this checklist apply to other HP MFPs and printers;
however, this checklist is tested and known to be successful only with the specified MFP
models.
•
Updated firmware: This checklist assumes that each MFP has updated system firmware and
Jetdirect firmware. You should use the latest firmware available, but realize that updated
firmware may have new features not covered in this checklist. Updated firmware is
available for download and installation at hp.com.
•
Web Jetadmin Version 10.x: This checklist is written for use with HP Web Jetadmin Version
10.1 and above.
•
Enterprise environment: This checklist is created and tested in a TCP/IP enterprise
environment. However, most of the settings are applicable to any network.
•
Network connection: This checklist assumes that each MFP is connected directly to a local
area network via Jetdirect or Jetdirect Inside (JDI). Other connections, such as directconnect via parallel cable or via USB are not covered in this checklist (this checklist
recommends disabling direct-connect ports).
•
Settings are only suggested: All settings in this checklist are meant only as suggestions for
best-practice security in common enterprise environments. Use it as a reference, and make
judgments about each recommended setting before configuring your MFPs.
•
Internet and intranet security: This checklist assumes that your network includes basic
security configurations and components. All MFPs should be installed behind network
firewalls and other standard tools such as updated virus protection applications.

Chapter 2: Threat Model
This section explains the types of security risks involved with operating MFPs in enterprise
environments.
As technology improves, malicious people (hackers) continue to find new ways to exploit networks.
They are beginning to target MFPs and other network peripherals to misuse resources or to gain
access to networks or the internet. Predicting the actions of a hacker is difficult, but HP is dedicated
to research in this area. This checklist represents some of HP's efforts to ensure that you can use HP
MFPs with confidence; however, you should continue to be ware and always remain vigilant. Use
other techniques with this checklist to help ensure that your network is resistant to compromise.
NOTE:
This is not a comprehensive treatment of these issues. This chapter is
only an introduction to the types of threats known to affect network
MFPs.
The Microsoft STRIDE model provides a valuable outline to categorize these known types of threats:
•
Spoofing identity
•
Tampering with data
•
Repudiation
•
Information disclosure
•
Denial of service
•
Elevation of privilege
The following sections explain how each type of threat relates to MFPs:
Spoofing Identity
Spoofing identity is masquerading as someone else to fool others or to get unauthorized access.
Here are some ways spoofing identity can relate to MFPs:
•
Placing another person's email address in the From address field of an email message.
Example: Someone could place the address of a co-worker in the From address field and
send embarrassing or malicious messages to others as though the co-worker wrote them.
•
Using another person's email credentials to log in to the email server to gain access to
address books
•
Using another person's email credentials to have free use of an email service
•
Using another person's email credentials to view that person’s email messages
•
Using another person's log on credentials for access to use MFPs or networks
•
Using another person's log on credentials for administrative access to MFPs
Chapter 2
HP LaserJet and Color LaserJet MFP Security Checklist
5
You can minimize the risks from identity spoofing in the following ways:
•
Protect the from address field in the MFP Digital Sending and Fax configurations.
•
Protect MFP disk access.
•
Configure authentication.
•
Configure the administrator password.
•
Configure SNMPv3.
Tampering with Data
Tampering with data can include any method of changing, destroying, or adding to information
that is flowing to or from an MFP or stored on it. Here are some ways tampering with data can
relate to MFPs:
•
Canceling another person's job. Someone could use a remote access tool to cancel
pending jobs. The person who sent a cancelled job gets no warning; only part or none of
the job is printed.
•
Intercepting a print job before it reaches the MFP, altering it, and sending it on to the MFP
•
Intercepting remote configuration data, such as communications between Web Jetadmin
and the MFP, to get passwords and other information
You can minimize the risks from data tampering in the following ways:
•
Disable Cancel Job button.
•
Disable Go (Pause) button.
•
Configure SNMPv3.
•
Prevent unnecessary remote access: close down all unused ports and protocols.
•
Configure HTTPS for EWS access.
Repudiation
Repudiation is using an MFP without leaving usage information. This includes preventing the MFP
from logging data or bypassing security checks such as user authentication. This also includes
finding ways to use an MFP without paying by bypassing job accounting software. Here are some
ways repudiation can relate to MFPs:
•
Accessing usage logs to delete entries
•
Removing origination information from file metadata
•
Bypassing user authentication
•
Using remote management software to access the MFP
You can minimize the risks of repudiation in the following ways:
Chapter 2
HP LaserJet and Color LaserJet MFP Security Checklist
6
•
Install Jetdirect 635n Print Servers or enable embedded IPSec to encrypt the data stream to
include log data and file metadata (look for this product at hp.com or contact your hp
product supplier).
•
Close unused ports and protocols.
•
Save copies of log data at a separate location
•
Add security solutions such as smartcard, swipe-card and thumbprint readers
Information Disclosure
Information disclosure is gathering information from an MFP and providing it to unauthorized users.
This can include authentication information, usage log information, or information from the contents
of a job. Such data stored on your hard drive is considered ‘at rest’ while data being transmitted
by your MFP device is considered ‘in transit’. Here are some ways information disclosure can relate
to an MFP:
•
Reading stored print jobs on the MFP hard drive.
•
Downloading log information
•
Downloading address books
•
Intercepting print jobs, copy jobs, fax jobs, or digital send jobs (such as email).
You can minimize the risks of information disclosure in the following ways:
•
Enable IPSec to protect data in transit. Although some devices include this feature
embedded, you may need to install an HP Jetdirect 635n (wired) or HP Jetdirect 690n
(wireless) Print Server accessory. (Look for this product at hp.com or contact your HP
product supplier).
•
Use hardware encryption to protect data at rest. Some devices may include an encrypted
disk. If not, you can add an HP Secure Hard Disk accessory to protect data stored on your
MFP. (Look for this product at hp.com or contact your HP product supplier).
•
Close unused ports and protocols.
•
Configure all possible password settings.
•
Configure authentication.
•
Configure SNMPv3 for Web Jetadmin.
Denial of Service
Denial of service is any type of interference with normal use of an MFP. This can include any of the
following:
•
Canceling or pausing the print jobs of others
•
Turning off the MFP remotely
•
Disconnecting power to the MFP
•
Removing the MFP formatter board
•
Disconnecting the MFP from the network
Chapter 2
HP LaserJet and Color LaserJet MFP Security Checklist
7
•
Causing interference with network communication to the MFP
•
Changing the network location of the MFP
•
Causing an error state that interrupts service
•
Changing access configurations
Here are some methods of minimizing opportunities for denial of service on an MFP:
•
Lock the control panel.
•
Lock EWS configuration settings.
•
Close unused ports and protocols.
•
Disable controls such as the Job Cancel button and the Go button.
•
Enable the resume feature to allow the MFP to resume operations after an error state.
•
Configure Job Timeout.
•
Control physical access to the MFP.
•
Lock physical access to removable hardware.
Elevation of Privilege
Elevation of privilege is any method of upgrading authorized access to include unauthorized
access. This can be any of the following:
•
Non-administrators changing settings to get administrator privileges
•
Unauthorized use of management software to provide access for other unauthorized users
•
Using management software to bypass job accounting functions
Here are some methods of minimizing opportunities for elevation of privilege:
•
Configure the administrator (device) password.
•
Configure SNMPv3 and HTTPS.
•
Lock the control panel.

Chapter 3: Basic Security for Multiple MFPs
This chapter explains how to configure security settings for one or more MFPs using HP Web
Jetadmin. It assumes that you have taken or plan to take reasonable steps to secure the network
environment in which your MFPs are operating. This includes configuring network firewalls and
providing up-to-date virus controls. If you need help doing this or are looking for information on
Jetdirect Firewall, ACL, Kerberos, PIN authentication, HP Digital Send Service, IPSec, IPv6, or Full
Hard Disk Encryption please refer to the chapter on Advanced Security.
Notes on the Process of Configuration
This checklist covers all relevant security settings available for MFPs. Testing shows that this
combination of settings is successful in the most common network environments as long as the
settings are executed in the correct order.
After each setting in the checklist is applied, it is important that you verify configuration to ensure
this order is maintained. If a setting was not applied, attempt to set that setting again. If you have
further issues with a particular configuration item, you can try using the individual configuration
pages, or setting that item through the EWS if available.
Keep in mind that every network is different. Configuring an MFP for your network may require
adjustments to this configuration. Be aware of your network environment and consider the right
configurations for your situation.
Also, keep in mind that each model of MFP may have unique sets of available settings. For
instance, LaserJet (black and white only) MFPs do not provide settings to restrict color printing.
However, Web Jetadmin lists the aggregate of all possible settings for all MFPs you are managing.
You can select settings for all MFPs, and each individual MFP will accept configurations according
to its capabilities and ignore settings that do not apply.
All of the settings in this chapter are found in HP Web Jetadmin, and you should use Web Jetadmin
to complete them. If possible, try to complete all of the steps in the correct order.
Tip:
Use a printout of the Settings List chapter to check off each item as you
go along.
Using Web Jetadmin and MFP Passwords
Web Jetadmin is a powerful tool that allows you to manage any number of MFPs and printers. It
provides the ability to configure a wide variety of features and services on the network. Without
proper security, Web Jetadmin allows malicious users the same conveniences for attacking your
network. Thus, configuring security features and passwords and updating them regularly for Web
Jetadmin and MFPs is important to network security.
This involves several passwords that limit access to important areas of the MFP. When you attempt
to make changes to configurations, the MFPs will require all applicable passwords. Web Jetadmin
keeps an encrypted cache of all of these passwords for each MFP whenever they are configured or
used. However, sometimes the cache can lose track of some credentials. Thus, you should keep a
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist
9
log of the passwords in a safe place. Web Jetadmin will prompt for passwords during the
configuration process if they are missing from the cache.
CAUTION:
Losing passwords can block access to an MFP. Be careful to record them
in a safe place. It is most important to remember the Bootloader
password. With it, it is possible to restore the MFPs to factory default
settings. Without it, the only way to restore the MFPs is to involve an HPauthorized service technician to reset the entire MFP. You may wish to
use a password vault program to organize and store all of the
passwords.
Here is a list of the passwords you should configure:
•
Web Jetadmin password (required during installation of Web Jetadmin)
•
SNMPv3 credentials
•
Bootloader Password
•
EWS Password
•
Device Password
•
File system password
•
Fax PIN
•
Device PIN (for MFP functions)
•
User PIN (for individual user accounts)
•
PJL password
Use good practices for setting and updating passwords (some of the password settings have
limitations on what and how many characters may be used):
•
Use alpha and numeric characters whenever possible.
•
For numeric only passwords use passwords with at least nine digits.
•
Use a different password for each password setting. Many of the latest password cracking
tools can follow patterns to make guessing easier.
•
Avoid using a pattern for passwords.
•
Change the passwords often with the exception of your HP Secure Hard Disk password.
Changing your HP Secure Hard Disk password (Drive Lock Key) causes a loss of all data
on your disk and system security settings
Use the maximum number of possible characters. Many of the password settings will
accept as few as one character, but one character is easy to guess. Current data shows
that nine characters or more are extremely difficult or almost impossible to guess using the
latest password cracking tools.
Use complicated passwords. Use a variety of character types. Some of the passwords
allow only numeric digits, but others can accept 96 or more different characters (upper
case, lower case, numeric, special characters, and punctuation marks).
•
•
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist

•
•
Use meaningless random passwords. Passwords that are real words or phrases are easier
to guess. The latest password cracking tools follow dictionaries to narrow down the
possibilities.
Record the passwords in a safe but hidden place. The passwords are designed to restrict
access to management options on the MFPs. Losing a password can eliminate your access
to settings. This is most important for the Bootloader Password. The Bootloader Password is
a permanent setting that can never be changed or reset without the correct password.
Getting started configuring MFP Security Settings
This section provides instructions for configuring the MFPs for best-practice security. All of these
settings are presented for HP Web Jetadmin Version 10.1 or later.
Note:
If you are setting this checklist for a group of several printers at once,
Web Jetadmin will display all supported settings for all the MFPs it is
managing, even though some of the MFPs may not support all of these
settings. Each MFP ignores settings that do not apply to it and continues
without issues. For instance, color settings are ignored for a non-color
MFP.
For the same reason, some of the settings may not appear in HP Web
Jetadmin if none of your MFPs supports them. Web Jetadmin displays
only the options that apply to the MFPs you are managing. For instance,
color settings will not appear if none of your MFPs has color. Ignore
recommendations in this checklist if they do not appear on your Web
Jetadmin screen.
Before you begin, be sure to install HP Web Jetadmin Version 10.1 or later, and have it working in
your network environment. You can find Web Jetadmin free for download and installation at the
following location on hp.com:
http://www.hp.com/go/webjetadmin
Be sure to update Web Jetadmin Version 10.1 or later with the latest upgrades available from HP.
See the HP Web Jetadmin Update page in the Product Update, Install menu.
Note:
This checklist was written using screenshots from Web Jetadmin 10.2
Setting up HP Web Jetadmin
Follow these instructions to prepare Web Jetadmin for configuring the MFPs:
1. Open Web Jetadmin to view the device list (Figure 1) that appears by default.
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist
11
Figure 1: Web Jetadmin showing the device list on the default view.
2. Check to see that the MFPs you wish to configure appear in the Device Model
List. If they are not in the list, use the Discovery options to find the MFPs on your
network.
Note:
This checklist does not include details on MFP discovery. See Web
Jetadmin user guidance for more information. In most cases, the MFPs
will already appear in the default view of Web Jetadmin.
It is possible for Web Jetadmin to lose contact temporarily with an MFP
that is configured for DHCP. Use the Discovery options to restore
contact, or configure the MFPs with static IP addresses.
3. Hold down the CTRL key and click to select the MFPs to configure in the Device List
view (Figure 2).

4. Click the Config tab in the lower half of the Device List view to show settings
available for configuration (Figure 3).
Figure 3: The Config tab displays settings available for configuration.
The Config tab contains all of the settings recommended in this checklist.
Tip:
If you are having a problem configuring a setting, try configuring it
using the individual device’s configuration page. You can also attempt
to configure the setting using the EWS of the MFP.
Sometimes Web Jetadmin can lose track of MFP credentials. If this
happens, some settings might fail. Clear the Web Jetadmin Device
Cache (see Web Jetadmin Help) and re-enter the MFP credentials.
The next step is to ensure that any installed HP Secure Hard Disks are configured:
Configuring HP Secure Hard Disk
If you have an HP Secure Hard Disk installed you need to verify data encryption is enabled (this
should happen by default after initial hard drive installation).
WARNING:
If your HP Secure Hard Disk is not already
configured to encrypt your data, consult your documentation to resolve
this issue. Failing to configure your HP Secure Hard Disk before starting
this checklist will reset all security settings to factory defaults and require
you to repeat this checklist again when you configure the drive.
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist
13
Follow these steps to use Web Jetadmin to verify your HP Secure Hard Disk is installed and
configured:
1. In the device list view, add the columns for Secure Disk and Secure Disk Status if
they are not visible. First, right click on the column area to the right of the existing
columns. Then select customize… from the drop down list (Figure 4).
Figure 4: Shows where how to reach the column customization menu.
2. In the next menu, you need to select the Secure Disk and Secure Disk Status columns
and transfer them to the Selected Columns list (Figure 5).
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist
14
Figure 5: Shows how to add the Secure Disk and Secure Disk Status columns to the columns selected for display.
3. In the listing of printers, check the Secure Disk and Secure Disk Status columns. The
Secure Disk column should indicate “Installed”. The Secure Disk Status column should
indicate ”Encrypted” (Figure 6).
Figure 6: Shows the Secure Disk and Secure Disk Status columns as Installed and Encrypted.
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist
15
Note:
If your MFP is reporting an installed HP Secure Disk but its status is
anything other than Encrypted it is recommended you resolve the issues
with your HP Secure Disk before continuing this checklist. If you do not
you may need to re-apply the entire checklist to the MFP. An example of
an MFP with a HP Secure Disk Installed that is not configured properly is
shown below (Figure 7).
Figure 7: Shows a HP Secure Disk with a status of Not Encrypted indicating an issue with the Disk that needs resolution.
The next step is to configure secure communications between HP Web Jetadmin and the MFPs:
Configuring SNMPv3
SNMPv3 provides encryption for communication between Web Jetadmin and MFPs. It helps to
ensure that only authorized and authenticated administrators have access to the configuration
settings of the MFPs. It also helps to ensure that no one can gather sensitive information, such as
passwords, usernames, and other codes, over the network while you are configuring the MFPs.
Note:
It is best to configure SNMPv3 by itself to ensure that the settings save
properly.
Follow these steps:
1. Click Security in the Configuration Categories menu (Figure 8) to view the options
for configuration. From the Security Options select SNMP Version Access
Control.
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist
16
Figure 8: The Security category and SNMP Version Access Control settings.
2. On the SNMP Version Access Control menu, and select the Enable
SNMPv3 checkbox (Figure 9).
Figure 9: Shows Enable SNMPv3 selected.
3. Once Enable SNMPv3 has been selected, and fills in the New User, the New
Authentication Passphrase, and the New Privacy Passphrase fields
(Figure 10) in the New SNMPv3 Credential section. See below for details.
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist
17
Figure 10: The Enable SNMPv3 option has been selected and the New SNMPv3 Credential section is complete.
The New User Name field can be any name you choose.
The New Authentication Passphrase field can be any word or phrase that is at least 8
characters.
The New Privacy Passphrase field can be any word or phrase that is at least 8
characters.
CAUTION:
These instructions are for the initial configuration of SNMPv3. Once you
finish this configuration, the MFPs will require these credentials
whenever anyone attempts to access settings over the network. Be sure
to remember these credentials and provide them only to authorized
users. If these credentials are forgotten, the only way to restore
communication between HP Web Jetadmin and the MFPs is to restore
the MFPs to factory default settings.
Web Jetadmin retains the SNMPv3 credentials for each MFP, and it will
not prompt for them as long as the settings remain the same. You can
clear the Web Jetadmin Device Cache to cause Web Jetadmin to
require the credentials again. Web Jetadmin stores the SNMPv3
credentials in an encrypted form.
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist
18
4. Scroll down to the SNMPv1 Settings section, and select SNMPv1 disabled
(Figure 11).
Figure 11: The SNMP Version 3 Only setting.
This setting limits all SNMP configuration communication to only SNMPv 3. Once applied your
MFPs will not allow SNMPv1 SET and SNMPv2 GET.
5. Choose Apply at the bottom of the SNMP Version Access Control configuration to
apply the settings to the selected devices. This will open the configure devices
dialogue box (Figure 12).

why the configuration failed.
Now, whenever you click Apply to configure settings, the MFP will check for the SNMPv3
credentials.
Note:
For convenience, Web Jetadmin stores the credentials for each MFP in
an encrypted format. However, Web Jetadmin may still prompt you for
credentials on occasion so remember the passwords you set.
7. Click Done to exit the Configure Devices dialogue, and continue with this checklist.

Configuring MFP Security Settings
The Security category includes many advanced security settings and password settings. If you
are attempting to configure a setting that is in the Security category and not listed in this section,
you should check the chapter on Advanced Security for multiple MFPs. To set the basic required
settings in this category follow the steps in the sections below.
Bootloader Password
The Bootloader password protects features, such as the MFP reset options that are available on the
MFP control panel. These features are not commonly known, but they can severely affect the MFPs
if they are executed improperly. The Bootloader password is not configured by default.
CAUTION:
Be very careful to remember the bootloader password that you provide.
Once you configure the bootloader password, the bootloader features
will be inaccessible permanently without it. The only way to restore the
default setting and clear the password is to provide the correct
password and set it with a blank password.
1. On the Config tab under the Security category page, select the Bootloader
Password option (Figure 31)

File System Password
When a File System Password is set, the MFPs will require the password whenever anyone or any
device requests access to the storage devices. To set the File System password follow the
instructions below:
1. Click to select File system Password (Figure 48).
Figure 48: The File system Password option.
2. Type an 8 character password in the File System Password field, and repeat it
exactly in the Confirm Password field.
Note:
When Web Jetadmin is used to configure MFPs, it saves all of the
passwords, including credentials for SNMPv3, in an encrypted device
cache. As long as an authorized administrator is logged into Web
Jetadmin, it will supply the passwords automatically without prompting.
3. Click the Apply button located in the bottom right hand corner to apply the
settings to the selected devices. This will open the configure devices dialogue box.
4. Review your settings and then click the Configure Devices button to execute the
configuration.

Secure File Erase Mode
This setting determines the level of overwriting applied to delete files during routine functions. This
includes removal of files for the Secure Storage Erase function. The settings are:
Non-secure Fast Erase does a standard erase with no additional security.
Secure Fast Erase overwrites files using one pass. This takes some extra time, but it provides
reasonable security.
Secure Sanitizing Erase overwrites files with three passes. It noticeably slows the MFP, but
it ensures that files are completely unrecoverable.
Use Secure Sanitizing Erase to meet stringent security requirements such as Department of
Defense standards.
Note:
Secure File Erase requires that the File System Password be configured.
If you are following this checklist in order this should not be an issue.
To set the Secure File Erase Mode follow these instructions:
1. Click to select Secure File Erase Mode (Figure 49), and view the options in the
dropdown menu.
Figure 49: The Secure File Erase Mode setting.
2. Select Secure Fast Erase (Figure 50) or Secure Sanitizing Erase if you
require maximum security.

Configuring MFP Digital Sending Settings
The Digital Sending category includes options for email and for send to network folder. This
includes settings for protecting the sender identification fields.
Note:
Some security-related settings that do not apply to LaserJet and Color
LaserJet MFPs might appear on the Digital Sending page. These settings
are for other types of HP MFPs. You should configure the settings that
appear in the instructions below. You may wish to configure the other
settings as a safeguard, but they are ignored on devices that do not
support them.
Auto Reset Send Settings
This setting governs how long after sending a job the device waits to log off the current user and
reset the control panel. Selecting delay before resetting the default settings allows users
to send multiple digital send jobs (email, send to folder, & fax) to a location without having to
retype all of the information in the control panel. It ensures that the information displayed on the
control panel resets automatically when a user walks away without clearing the menu. The setting
only applies to digital send jobs. To configure this setting:
1. Click to select Auto Reset Send Setting from the Digital Sending category
(Figure 52).
Figure 52: The Time-outs options.
2. Select Delay before resetting the default settings.
3. Choose a reasonable time to allow users to send multiple jobs, but also to ensure
that the information will not be left on the control panel for too long after the user
walks away.
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist

Default From Address
HP recommends configuring the default from address to ensure that no one can send email using
false or misleading identification. If you are using LDAP Authentication, the MFP will use the email
address of the authenticated user to replace the default from address. To configure the Default
'From: ' Address:
1. Scroll down, and click to select Default 'From:' Address (Figure 53).
Figure 53: The Default From Address options.
2. Click to select Prevent user from changing the Default 'From:' Address.
3. Fill in the Email Address field with any address that includes the ampersand (@).
Tip:
You may wish to use the email address of an administrator who can
receive responses such as e-mail and send notices and failures.
4. Fill in the Display Name and the Default Subject fields as desired.

Configuring Final Settings
Some of the MFP settings should be configured independently from other settings and only at the
end of this checklist. Follow these instructions for the final settings:
Disabling Direct Ports
The Disable Direct Ports feature disables the USB and Parallel ports on the MFPs. It ensures that only
network-connected computers can access the MFPs. In order to configure this feature, each MFP will
turn off and turn on automatically. To disable these ports:
1. Go to the Security page, and click to select Disable Direct Ports (Figure 55).

Click to select the Disable Direct Ports option to the right.
Select Yes.
Click Apply at the bottom of the page.
Wait for a few minutes to allow all of the MFPs to restart. Do not continue until all
of them are at the READY state.
Disabling EWS Config
EWS Config was required for configuring this checklist, but it should be disabled during normal use
of the MFPs. To disable EWS Config:
1. Go to the Network category, and click to select Enable Features (Figure 56).
Figure 56: The Enable Features option.
2. Click to disable EWS Config.
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist

Note:
This setting disables configuration from the MFP EWS. It also disables all
EWS-related settings from Web Jetadmin (they will disappear from Web
Jetadmin menus). With this setting configured, the only way to make
changes to the EWS settings again is to re-enable them using Web
Jetadmin. Always remember to disable EWS Config after making
changes.
Your MFPs are now securely configured.
Chapter 3
HP LaserJet and Color LaserJet MFP Security Checklist

Chapter 4: Advanced Security for Multiple MFPs
This chapter gives some tips for configuring more advanced security settings for one or more MFPs
using HP Web Jetadmin. These features should be set up before locking down your MFPs using the
settings in the previous chapter. This allows adequate testing of your security solution to be
completed while you still have open access to your devices. If you are looking for information in
this section that is not contained in this document you can refer to the MFP User Guides and the HP
Jetdirect Administrator Guide for more information. You can find these documents and more
information by searching for it at hp.com.
Access Control List (ACL)
The ACL limits network access to the MFPs to only the IP addresses or subnets that you specify. This
includes printing and all other access. Thus, to access the device an administrator must use a
computer that is on the list, have the correct Web Jetadmin password, and then have the correct
SNMPv3 credentials to manage the MFPs.
The following MFP models also have a Jetdirect Firewall feature along with the Access Control List:
• HP LaserJet M3027 MFP
• HP LaserJet M3035 MFP
• HP LaserJet M4345 MFP
• HP LaserJet M5025 MFP
• HP LaserJet M5035 MFP
• HP LaserJet M9040 MFP
• HP LaserJet M9050 MFP
• HP Color LaserJet CM3530 MFP
• HP Color LaserJet CM6030 MFP
• HP Color LaserJet CM6040 MFP
HP Web Jetadmin may not provide options to configure the Jetdirect Firewall settings. Look for them
in the MFP EWS.
Note:
Keep in mind that the ACL is not configured until at least one computer
is in the list. When it is configured, no computer outside the list will have
access to the MFP including printing.
Follow these steps to configure the ACL:
1. On the Config tab click Access Control List (Figure 57) under the Security
Category.
Chapter 4
HP LaserJet and Color LaserJet MFP Security Checklist
61
Figure 57: The Configuration Categories Menu Network option.
2. Add an IP address or a net mask by filling in the IP Address or Mask fields.
CAUTION:
Be sure to include the IP address of the computer that is running Web
Jetadmin (it can be a computer other than the one you are using).
Otherwise, the ACL will block your access, and you will not be able to
continue.
The Mask option requires an entry in the IP address field to determine
the subnet for which to grant access. If you set a mask be sure it is
correct before moving on.
3. To make sure all of the MFPs are configured with your new listings, click Clear all ACL
Table entries the first time you add a listing.
Note:
To find out which IPs are configured in the ACL of a single MFP, open
the device in Web Jetadmin and navigate to the ACL options (all of the
MFPs should be the same if you are configuring them all at once). It will
list the IP addresses or subnets that are already configured.
4. Check the checkbox for Check ACL for HTTP access to ensure that the ACL
restricts access to the MFP EWS through HTTP.
Note:
These ACL options allow you to add one IP address or one mask at a
time. To add more IPs or masks, repeat these steps. Remember to
deselect Allow Web Server (HTTP) access each time.

Authentication Manager
The Authentication Manager allows you to customize access to functions of the MFP. You can use
these options to provide varying services to different groups of people.
1. Click to select Authentication Manager (Figure 58).
Figure 58: The Authentication Manager options.
Note:
Be sure to select only the authentication features that you plan to
configure for the MFPs selected. Many of the options available (such as
LDAP, Kerberos, and Digital Send Service) require additional solutions
on the network for support.
2. Click the dropdown menu next to Log in at Walk Up, and select from the list
(Figure 59).
Chapter 4
HP LaserJet and Color LaserJet MFP Security Checklist
63
Figure 59: The drop down menu for Log in at Walk Up.
Choosing an authentication method for Log in at Walk Up causes the MFP to require
everyone to log in for access to the control panel menus. You can choose to require further
authentication for specific functions of the MFP.
Choose an authentication method for each device function as desired. If you choose to use
different log in methods for each device function, the MFP will require authentication as
needed. The MFP automatically allows authenticated users to continue whenever they are
allowed to use a feature.
Note:
The DSS Secondary E-mail function and the DSS Workflow function
require HP Digital Send Service to be installed on the Network. Digital
Send Service is an additional solution offered at hp.com.
Choose an authentication method for Future Installations as desired. This
automatically requires authentication for new solutions that may be installed on the MFP.
You should choose a method for this option as a best practice for security even if you do
not expect to add solutions to the MFPs.
Group 1 PIN and Group 2 PIN
You can use PIN Authentication with other authentication features to restrict use of the MFPs further.
For instance, you can require all users to login at walk up using the LDAP system and then require
group 1 PIN for access to the copy function and group 2 PIN for access to the fax function.
Configure PIN Authentication as desired (Figure 60).
Chapter 4
HP LaserJet and Color LaserJet MFP Security Checklist
64
Figure 60: The Group 1 PIN and Group 2 PIN Authentication options.
Click to select PIN Authentication, and enter PINs as desired. Be sure to repeat the PINs
exactly in the Confirm PIN fields.
Note:
If your network includes NTLM service, configure NTLM. This option
specifies the authentication method to use when your MFP executes a
send to folder job. We recommend using the highest authentication
available.
Chapter 4
HP LaserJet and Color LaserJet MFP Security Checklist
65
LDAP
If your network includes LDAP, configure the LDAP Authentication options (Figure 61).
Figure 61: The Accessing the LDAP Server options.
These settings enable the MFPs to require a user's logon credentials for use of the MFPs. This is
related to the LDAP access options in the Digital Sending category, which enable the MFP to
use the LDAP address book; however, the SSL certificate options for both configurations appear
on the Digital Sending page.
Note:
These instructions assume that the LDAP server is configured for SSL. If
you have this feature available, you should go to the Digital Send page
(see the Digital Send section, above) to upload a certificate created by
the Certificate Authority server on your network.
Select Simple over SSL in the LDAP Server Bind Method: dropdown menu.
Note:
If possible, you should choose Simple over SSL for the bind method and
configure the LDAP server for communication over a secure SSL channel.
This also requires that you generate SSL certificates and upload them to
the MFPs using the LDAP Access options in the Digital Sending page
(explained earlier).
Chapter 4
HP LaserJet and Color LaserJet MFP Security Checklist
66
If you choose Simple for the bind method, usernames, email addresses,
passwords, and other data will be sent over the LDAP protocol in clear
text.
Fill in the remaining fields according to your network configuration.
If your network has Kerberos authentication capabilities, configure the Kerberos
Authentication options.
User Pin Authentication
User PIN Authentication allows you to restrict access to MFP functions by specific users. A user will
be required to log in by PIN in order to use a restricted function on the MFP (see the
Authentication Manager section above). This feature also provides a way to add user email
addresses to the MFP address book. You can configure up to 2000 users in this feature.
Configure User PIN Authentication (Figure 62) as desired.

Chapter 7: Ramifications
Raising the level of security on HP MFPs requires giving up some conveniences and usability. This
section explains some of the compromises you can expect from configuring the settings
recommended in this checklist. Keep in mind that this is not a comprehensive list. You should test
each MFP in your network environment to understand the implications of these settings and
configurations.
The following sections explain some of the known ramifications of each recommended setting:
Initial Settings
•
•
Configuring Advanced Security Settings (ACL, Firewall, LDAP, Kerberos, etc.)
There are many advanced security settings that you may be using as part of your infrastructure
or print solution. These settings should be configured and tested before locking down your
devices with this checklist. If you are unsure how a setting may affect an advanced security
configuration see the advanced security section, or test the setting on a single device before
applying it to your fleet.
Configure HP Secure Hard Disk.
HP Secure Hard Disk is a disk that encrypts all data stored on your hard drive.
Failure to set up this device before setting the NIST checklist or other MFP settings will result in
a loss of all previous settings when the HP Secure Hard Disk is installed and set to encrypt
data.
Once the HP Secure Hard Disk is installed, the hardware encryption is transparent to the
device. It should have no impact on subsequent configurations unless you:
•
-
Remove the HP Secure Hard Disk and install a new one
-
Use the “reinitialize” feature which will result in cryptographically erasing your entire
disk, or
-
Change the password, which will also result in reinitializing the encrypted disk
Enable SNMPv3
SNMPv3 is a secure protocol that encrypts configuration data transmitted over the network.
Web Jetadmin accesses most of the MFP configuration settings through the MFP SNMP ports.
Once SNMPv3 is configured, the MFPs will prompt for the credentials every time anyone tries
to configure settings using Web Jetadmin or any other tool. However, Web Jetadmin includes a
convenient device cache feature that stores all of the passwords and credentials for each MFP.
Whenever an authorized Web Jetadmin administrator makes a change, Web Jetadmin
automatically provides the credentials without prompting. Thus, the administrator is required to
remember the credentials only when the device cache credentials are outdated. The device
cache is secured by encryption, and Web Jetadmin allows only the authenticated administrator
to log in and manage the MFPs. Be sure to configure a robust password for Web Jetadmin.
With SNMPv3 configured, an unauthorized user attempting to access the MFP configuration
settings will observe a prompt for the SNMPv3 credentials. The MFP will not disclose which
credentials are incorrect; it will only revert to the prompt for credentials.
SNMPv3 causes some slowing of the configuration process due to the additional time taken to
encrypt the data.
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
75
Disabling SNMPv1 disables SNMPv1 GET and SNMPv2 SET commands. Any solution or
software that requires SNMPv1 or SNMPv2 will not function. If you require these to be
enabled be sure to set the community name to something that would be difficult to guess.
Device Page Settings
•
Set I/O Timeout to End Print Job. The I/O Timeout to End Print Job allows you to specify
the amount of time a device should wait between packets before canceling a job. Setting this
timeout will help prevent jobs formed or sent incorrectly from tying up a print resource. If you
are on a busy network or spool large jobs real time that may cause packet gap set this setting
high enough to accommodate your environment.
•
Enable Job Hold Timeout. Job Hold Timeout is related to the Job Retention setting below.
It permanently deletes stored jobs (except fax) that are held past the allowed time. This ensures
that the stored jobs are not accessible after a time, and it ensures that the hard drive is cleared
periodically.
Job Hold Timeout requires that users are mindful of their print jobs. They will not be able to
recover jobs that are deleted after the timeout period. Jobs are deleted securely according to
the Secure File Erase setting (appears later in this checklist).
•
Enable Job Retention. Job Retention is a feature of the MFP that saves fax or print jobs on
the hard drive for printing when the user is present. The security implication is that a user can
be sure others will not be able to see the printed documents. For printing, a user sets the PIN at
the time of sending the print job to the MFP. For fax printing, the PIN is configured for all
incoming jobs using Web Jetadmin. The MFP will require the PIN number at the control panel
before it will print the job.
Configuring Job Retention enables more efficient use of the MFP hard drive. Thus, you should
configure Job Hold Timeout and other related settings.
NOTE:
Stored faxes are not affected by the Job Hold Timeout.
Network Page Options
•
Configure Enable Features options (do not disable EWS Config at this point). These
options enable or disable various supported features for the MFP. These features are designed
for access and convenience on the network, but they should be disabled when not in use
(sometimes only for best-practice control of the networking capabilities). The following list
explains the ramifications of each feature:
•
Disable Telnet Config. Telnet Config is an access point used by some older (legacy)
printer management tools. Jetdirect also supports some Telnet commands. Telnet Config
transmits data in clear text, and it should not be used. With it disabled, MFPs will deny
access to Telnet sessions.
Web Jetadmin does not use Telnet Config; thus disabling it has no affect on it. It disables
other tools, but Web Jetadmin is the only solution recommended for managing HP MFPs.
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
76
•
•
Disable SLP Config. SLP Config accommodates software using SLP as a discovery
mechanism. For example disabling SLP Config on some Novell networks (depending on
how Novell is configured) would cause Novell to not recognize the MFPs on the network.
Thus, if your network uses these features of Novell, you should enable SLP Config. If you
use software other than HP Web Jetadmin with your HP MFPs please test this feature before
disabling it. HP Web Jetadmin is not affected by this setting,
•
Disable FTP Printing. FTP Printing enables files to be sent to the printer via FTP for
printing on the MFP, enabling FTP Printing also allows you to upgrade your printer
firmware by sending the firmware via FTP. HP recommends disabling it and using Web
Jetadmin to upgrade firmware. MFPs will deny access to FTP sessions.
•
Disable LPD Printing. LPD Printing is the protocol necessary for printing in UNIX,
HPUX, or Linux environments. You should disable LPD Printing unless your network includes
UNIX workstations that might print using the MFPs. With this option disabled, MFPs will
deny access to UNIX machines.
•
Enable 9100 Printing. 9100 Printing should always be enabled. It is the standard
printing protocol used by MFP print drivers. Disabling 9100 Printing would disable all
printing for most users.
•
Disable IPP Printing. IPP Printing is a protocol for printing over the internet or locally.
Unless you have a requirement for IPP printing it should be disabled. With it disabled, the
MFPs will deny access to direct printing from the Internet. Print jobs generated from web
browsers using the installed print driver are not affected.
•
Disable MDNS Config. MDNS Config resolves host names with IP addresses in small
networks without DNS servers. Most enterprise networks include DNS servers and do not
require this service. With this option disabled, a non-DNS network will not recognize the
MFPs. If your network does not include a DNS server, you should enable MDNS Config.
•
Disable IPv4 Multicast Config. IPv4 Multicast Config configures multiple devices
simultaneously over the network. You should always disable IPv4 Multicast Config, and
use Web Jetadmin for managing MFPs.
•
Disable WS-Discovery. WS-Discovery enables network hosts that support WSDiscovery to discover printers and devices on the network. Unless you are in an IPv6 or
Windows Vista/Windows 7 only environment there are other protocols you can use to
discover your printers.
Configure Encryption Strength to High. The encryption strength setting covers
communication between a PC and the Embedded Web Server. When HTTPS is configured (as
recommended in this checklist), communication is encrypted according to this Encryption
Strength setting.
With Encryption Strength set to High, users will find that the EWS are accessible only from
web browsers that support that level of HTTPS communications.
This checklist recommends disabling EWS Config during normal use of MFPs. This removes all
access to the EWS; however, you should configure this setting for times when you temporarily
enable EWS Config to make changes to configurations.
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
77
•
Enable HTTPS, and configure the setting to Encrypt all web communication. This setting
enables encryption for configuration data between the PC and the MFP EWS. It prevents
sensitive data such as usernames and passwords from passing over the network in clear text.
This setting is related to the EWS Encryption Strength setting explained earlier.
Web browsers that do not support SSL and high encryption strength will not be able to access
the MFP EWS.
This checklist recommends disabling EWS Config during normal MFP operations and enabling
it temporarily for changes to configurations. This setting ensures that the network traffic is
secure during those configurations.
•
Disable IPX RCFG Support. The IPX RCFG Support setting (sometimes called RCONFIG)
allows remote configuration from IPX/SPX servers. Web Jetadmin may use RCFG to configure
Novell NetWare queue-server linkages on older Jetdirect print servers. You should disable IPX
RCFG Support unless your network has Novell and older Jetdirect print servers.
With IPX RCFG Support disabled, MFPs will deny access to Novell.
When you click Apply for this setting, a caution message will appear to alert you that you are
disabling certain types of Novell access. Click OK to go ahead with disabling it.
•
Configure Job Timeout. The Job Timeout option enables the MFPs to move on from jobs
that lack proper end of job signals. The MFPs will be able to switch protocols to continue with
other jobs rather than waiting indefinitely for improperly formatted jobs to finish.
•
Set the Privacy setting as desired. The Privacy setting is included in this checklist to inform you
of its purpose: it allows HP to collect statistical data on the use of MFPs. HP uses such
information to help improve the design and development of MFPs. HP will not collect networkspecific or personal data. For information on HP privacy policies, read the Hewlett-Packard
Online Privacy Statement available by clicking privacy statement at http://www.hp.com.

•
Disable unused Protocol Stacks. These options provide for the various types of network
communication to the MFPs. Closing down unused protocol stacks is affective toward better
network security. See the ramifications of each option below:
•
Disable IPX/SPX. IPX/SPX is the network protocol for Novell. Disabling it prevents
printing and all other communications with Novell non-TCP/IP components. With it
disabled, Novell non-TCP/IP components will not recognize the MFPs on the network.
•
Enable TCP/IP. TCP/IP is the standard network protocol for MFP operations. It provides
the necessary network communication for printing and for configuration. It should be
enabled during normal use of MFPs.
•
Disable DLC/LLC. DLC/LLC is used in small networks in which routing is not required. The
MFPs include it for compatibility with older HP products.
•
Disable AppleTalk. AppleTalk is used with older Apple computers. You should disable
it unless your network includes older Apple or Macintosh computers. With it disabled MFPs
will not appear on the network for these computers.
Disable Web Services Print. This disables the Microsoft WSD Print services supported on the
HP Jetdirect Print Server. If this feature is enabled someone with a host that supports Web
Services Print can discover IP Addresses and other information about the printers in your
environment.
Security Page Options
•
Configure Bootloader Password.
The Bootloader Password protects against accidental or unauthorized intentional access to the
MFP Bootloader settings. These settings are similar to the BIOS settings on a PC. They affect the
services that are loaded when the MFP is turned on. The Bootloader Password setting is
permanent. There is no way to reset it or to change it without providing the correct password.
Thus, it is extremely important to use a password that can be remembered and to record the
password in a safe place.
•
Configure color restriction settings. If your network includes Color LaserJet MFPs, you can
configure settings to restrict the use of color printing by users and by applications.
With color restriction settings configured, an MFP will print only in black and white for
restricted users or applications.
•
Configure Control Panel Access Lock to Maximum Lock. Control Panel Access Lock
denies access to configuration settings from the MFP control panel. This ensures that no one will
be able to change configuration settings from the control panel.
This setting places a lock icon on the affected settings on the control panel. If a user selects a
locked setting, the control panel states that access is denied. Access can be restored only by
changing the Control Panel Access Lock configuration using Web Jetadmin (assuming that
you are following all of the recommendations in this checklist).
The Control Panel Access Lock prevents everyone from accessing settings on the control panel.
There is no way to give access to authorized users. The MFP does not include functionality to
setup authorization for control panel controls.
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
79
The maximum Control Panel Access Lock closes all access to the fax menu. This includes the
options to Cancel All Pending Transmissions and Cancel Current Transmission. If
you wish to provide these options, use Intermediate Lock.
•
Configure the Embedded Web Server Password. The EWS password restricts access to
the configuration settings in the EWS. When configured, the MFP requires the password
whenever anyone or any application attempts to make changes to the EWS settings. Keep in
mind that the settings provided in the EWS are also accessed by Web Jetadmin. Thus, the
MFPs will require the EWS password from Web Jetadmin whenever it attempts to access these
settings.
Web Jetadmin keeps all passwords and credentials in the encrypted device cache. It will
automatically provide the EWS password to the MFPs whenever they MFPs prompt for it.
The EWS password is synchronized with the device password, which is recommended later in
this checklist. Whenever you change either password, the MFP will change the other one to be
the same.
•
Configure the PJL Password. The PJL password prevents unauthorized users from configuring
certain features of the MFP. It requires the password to change these settings via Print Job
Language (PJL) commands.
With the PJL Password configured, the MFPs will deny access to commands that attempt to
change default settings without the correct password.
•
Disable Printer Firmware Update. Printer Firmware Update enables the MFPs to
accept printer firmware updates from various sources. Disabling it ensures that no one can
send firmware updates to the MFPs. If this feature is disabled it may still be possible to update
the firmware manually through the boot loader if you have not safeguarded this option.
HP recommends updating firmware whenever it becomes available at hp.com. You should
enable Printer Firmware Update to perform the upgrades and then disable it again during
normal use of the MFPs.
With Printer Firmware Update disabled, the MFPs will deny access whenever anyone
attempts to upgrade the firmware.
•
Configure Authentication (LDAP, Kerberos, Device PIN, or User PIN). Authentication requires
users to log on for use of the MFPs.
•
Configure Authentication Manager. The Authentication Manager provides the settings to
require log in for use of the MFP. It is important to be sure to configure the authentication
methods (LDAP, Kerberos, Device PIN, or User PIN) you wish to enforce in the authentication
manager. With authentication enabled, MFPs will deny access to users who cannot supply the
correct credentials.
•
Set the Device Password. The Device Password helps prevent unauthorized users from
changing configurations in the MFPs. The MFPs will deny access to configuration settings
without the password.
Web Jetadmin keeps MFP credentials in its encrypted device cache. It will not prompt for the
device password of an MFP that it manages.
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
80
The Device Password is synchronized with the EWS password. If you change either of
them, the MFP will change the other one to be the same.
•
Disable Allow Use of Digital Send Service. HP Digital Sending Software is a useful tool
for managing MFP digital sending. It is available for purchase at hp.com. HP recommends
using Digital Send Service, but it is not covered in this checklist. Thus, this checklist
recommends disabling it unless you are using it.
With Allow Use of Digital Send Service disabled, no one can manage the MFPs with an
installation of Digital Send Service. The MFPs will deny access.
•
Disable Allow Transfer to New Digital Send Service. This setting is related to the
previous setting. If you allow use of Digital Send Service, it is possible for any installation of
Digital Send Service to take over management of an MFP. Disabling this setting ensures that the
MFPs will allow only one Digital Send Service computer to manage the MFPs.
With this setting disabled, the MFPs will deny access to a second Digital Send Service
attempting to take over management.
Fax Page Options
•
Configure the Fax PIN. With the fax PIN configured, the MFP requires the Fax PIN be provided
before access to held fax jobs is gained at the control panel. This improves security by ensuring
that printed faxes are not left in the output trays where unauthorized personnel might see them.
NOTE:
Stored faxes are not affected by the Job Hold Timeout.
The Fax Printing options limit access to timely faxes. You may wish to provide the PIN to a
number of people to ensure that someone can print a fax on demand. You can also configure fax
alerts to ensure that personnel will know when a fax arrives even though it is not printed upon
arrival.
Additional Fax Configuration
Configure the number of Fax Speed Dials with the Embedded Web server. With the number of fax
speed-dials configured and access to these locked down no one can tamper with you speed-dial
settings from the front panel of the MFP.
Embedded Web Server Page Options
•
Configure Embedded Web Server Configuration Options. These options limit some of
the EWS features that can be misused:
•
Enable Outgoing Mail. The MFP sends some email, such as automatic fax notifications
and consumables alerts, depending on configurations. This Outgoing Mail feature does not
affect the MFP send to email functions. It also is not known to affect network security. If you
use fax notification or other automatic email alerts, you should enable outgoing email.
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
81
•
Disable Incoming Mail. Some network solutions can send commands to the MFP via
email. If your network uses any of these solutions, you should enable Incoming mail.
Otherwise, disable it as a best practice. This setting does not affect any other use of the
MFP. With this setting configured, the MFPs will ignore all incoming emails.
•
Disable Cancel Job Button. The EWS provides a Cancel Job button that allows users to
cancel jobs that are pending in the queue. This includes canceling jobs sent by other users.
Thus, disabling the Cancel Job button removes the ability to cancel jobs remotely (and
anonymously); however, users will be able to cancel their own jobs from the printer driver
or from the control panel.
•
Disable Go Button. The Go button is the EWS Pause/Resume button, which enables
users to pause operations, such as print jobs, indefinitely. Disabling the Go button removes
it from the EWS preventing users from delaying jobs or even denying service to other
users; however, users will be able to pause or resume their own jobs from the print driver
or from the control panel.
•
Disable Command Invoke. Command Invoke is a legacy feature that does not apply to
the MFPs. Disabling it is good security practice to ensure that all possible access to it is
closed.
•
Disable Command Download. Command Download is a legacy feature that does not
apply to the MFPs. Disabling it is good security practice to ensure that all possible access
to it is closed
•
Disable Command Load and Execute. Command Load and Execute accommodates
add-on applications (Chailets), such as workflow programs and job accounting programs.
Disabling it stops the MFPs from running Chailets when it starts up. This function is called
Service Loading in the EWS. If your network uses Chailets, you should enable Command
Load and Execute. If not, you should disable it to prevent users from installing this type of
application.
You may wish to (turn off the MFPs and turn them on again (power cycle) after disabling
Command Load and execute. This will stop applications that may be already loaded and
running.
With this setting configured, the MFPs will ignore all add-on applications.
•
Disable Print Service. Print service allows users to send print-ready files such as PDF files
directly to MFPs for immediate printing. This feature is available to anyone who has access
to the EWS. Disabling it ensures that only users with the MFP Print driver installed can send
print jobs to the MFPs.
With Print Service disabled, the print options do not appear on the EWS.
File System Page Options
•
Configure File System External Access. The File System External Access settings shuts
down access to the MFP file system (storage devices and configuration settings) through
protocols and ports. They eliminate access from various types of management tools. HP
recommends shutting down all unused access to the file system. See the ramifications for each
protocol below.
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
82
NOTE:
Some storage management tools, such as the Web Jetadmin Device
Storage Manager (a Web Jetadmin add-on available in the Product
Update navigation mode), use some of these protocols to access the file
system. You might consider enabling these protocols only to update
configurations and then disable them during normal MFP operation.
Also, note that disabling PJL and PML only affects file system access, but
disabling NFS shuts down the protocol for the entire MFP.
•
Disable PJL access. PJL (Printer Job Language) includes capabilities to manage
configurations in the form of commands inside print jobs. Some of these commands can
access MFP storage devices. Disabling PJL access to the file system disables only the
commands that affect the file system. This will not affect the preferences available for
normal print jobs.
With PJL access disabled, the MFPs will ignore PJL commands that attempt to access the
file system.
•
•
Disable PostScript access. The PostScript protocol enables programs such as Adobe®
products to access the MFPs directly for printing and for access to fonts. Some of the
commands it uses can access MFP storage devices. Disabling PostScript access to the file
system disables only the commands that affect the file system. This will not affect the
preferences available for normal print jobs, but could affect interoperability with third party
products.
•
Disable PML access. PML (Printer Management Language) is an HP proprietary protocol
that manages MFPs. Web Jetadmin uses PML for many of its configuration settings.
Disabling this PML access eliminates the PML commands that affect access to the storage
devices even for Web Jetadmin. If you wish to make changes to the file system, enable
PML access to make the changes, and disable it again. With this setting, MFPs will ignore
PML commands that attempt to access the file system.
•
Disable NFS access. The NFS protocol is used by UNIX, and Linux, and Norton systems.
Disabling it disables the entire protocol for the MFPs. With this setting, MFPs will ignore all
NFS requests. If your network uses these protocols, you should enable NFS.
Configure the File System Password. The File System password feature restricts access to
the Secure File Erase Mode, Secure Storage Erase, and External File System Access Settings.
This setting is important because it helps protect data stored on the MFPs. It does not affect
normal use of the MFPs such as job storage.
Users attempting to make changes to the file system settings or attempting to access data
through network ports will be required to provide this password. Without the password, the
MFP denies access to the File System and to File System configurations.
Web Jetadmin stores the file system password in its encrypted device cache. It automatically
provides the password when the MFPs request it.
•
Set the Secure File Erase Mode to Secure Fast Erase or to Secure Sanitizing Erase.
Secure File Erase enables the MFPs to overwrite storage space whenever files are deleted. This
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
83
ensures that the original data is destroyed.
Secure Fast Erase mode overwrites files one time. It slows MFP performance a bit, but it
provides reasonable security for most situations.
Secure Sanitizing Erase overwrites files 3 times. It slows MFP performance considerably, but it
provides even more assurance that the data is not recoverable. If your network is required to
meet stringent security requirements such as DOD regulations, you should use Secure Sanitizing
Erase.
Digital Sending Page Options
•
Configure Auto Reset Send Settings to Delay before resetting the default settings,
and type a number of seconds to delay. This setting enables the MFPs to remove email
addresses or fax information from the control panel if a user forgets to reset it. The
authenticated user performing a digital send job is also automatically logged off.
With the timeouts configured, an MFP control panel will revert to the default screen, and a user
will not be able to reuse addresses and other destination data beyond the timeout period.
•
Configure the Default From Address, and select Prevent users from changing the
Default From Address. The Default From Address setting allows you to place a
standard and consistent address in the From field of emails sent from the MFP. Selecting
Prevent users from changing the default from address ensures that users are unable
to tamper with the address in the From field, and that it is automatically populated with the
default or the authenticated users email address. These features ensure that nobody can use the
MFP to spoof identity or provide erroneous addresses. Consider using a From address that
describes the location or the type of MFP, or use a real address to monitor reply messages.
With the Default From Address configured, no one can change the From address in email
messages. The address you configure is the only address anyone can use.
Final Configurations
•
Disable Direct Ports. This setting shuts down the MFP parallel ports. It restricts access to only
network connections.
Shutting down the parallel ports ensures that no one can configure the MFPs or print using
these connections. Thus, users will not be able to bypass job accounting or restricted access,
such as color printing, by using alternative connections.
This setting causes the MFPs to turn off and turn on. They will be out of service during this time.
This is also the reason this setting should be configured independently of other setting
configurations. If you attempt to configure this setting with other settings, the other settings will
likely fail. This is because Web Jetadmin temporarily loses contact with each MFP while the
MFP is restarting. Be sure to wait a few minutes until all of the MFPs are online and ready
before executing another configuration.
With Direct Ports disabled, the parallel and USB ports are turned off, and the MFPs behave as
if the ports do not exist.
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
84
•
Disable EWS Config. Disabling EWS Config removes the EWS from the network. They
become unavailable to everyone. This eliminates many risks to security.
Since all of the EWS configuration settings are available in Web Jetadmin, there is no need to
have them available anywhere else. Keep in mind, though, that disabling EWS Config also
eliminates the affected settings from Web Jetadmin. Thus, you will have to enable EWS Config
temporarily to make changes to the configurations, and then disable it again.
With EWS Config disabled, the MFPs will not provide the EWS on the network. Web
browsers will return with no such web site found. This removes some conveniences that EWS
provide, but all of the functions that you would want to provide to users are available using the
MFP drivers or the control panels.
Overall Limitations
This overall configuration provides a high level of network security for HP MFPs. At the same time, it
introduces some limitations to the conveniences designed into the MFPs. Here are some known
affects of this overall configuration:
•
Extra steps to use MFPs: Users will be required to provide usernames and passwords at the
control panels before they can use the MFPs.
•
No access to control panel configuration menus: The control panels block access to
configuration settings for anyone. Configuration settings will be available only on Web
Jetadmin. Some settings will have to be enabled using Web Jetadmin before they can be
accessed.
•
No way to cancel print jobs from the control panel: The MFPs will not allow a user to cancel
the print jobs of other users. The user would have to go to the person who submitted the job
and ask that person to cancel it.
•
No way to cancel a fax job: The maximum lock setting on the control panel includes removing
the fax job cancelling options. Once a user selects Send, there is no way to stop an outgoing
fax (other than disconnecting the phone line). You can enable fax cancelling by configured
Control Panel Access Lock to Intermediate Lock.
•
Extra steps for printing faxes: A user will be required to provide a fax PIN before printing a
fax.
•
No Embedded Web Servers: Disabling EWS Config disables the entire EWS feature.
No way to change the From Address on email send jobs: Depending on the capabilities of your
network, the MFPs will place either a default from address or the user's email address of the user
who logged into the MFP. It will provide no method to change it.
Chapter 7
HP LaserJet and Color LaserJet MFP Security Checklist
85
Chapter 8: Physical Security
Many of the most notable features of HP MFPs involve hard copy documents. MFPs can print them,
scan them, send them to email, send them to network folders, send them to other printers, and fax
them. Handling hardcopy documents can involve a variety of activities that can lead to compromise
of data security:
•
Leaving documents in the printer output trays exposed to possible unauthorized viewers.
•
Leaving documents in Automatic Document Feeder (ADF) or on the flatbed scanner exposed to
possible unauthorized view.
These are common-sense security risks. Use PIN printing and PIN fax printing to ensure that
authorized users are present during printing. Stay with the MFP while using the ADF or the flat bed
scanners. Keep the MFP in an enclosed room to allow for controlled access for sensitive printing or
scanning.
Physical security also involves access to the location where an MFP is installed. Limiting physical
access to an MFP can easily prevent many security risks from unauthorized users. Such risks include
the following:
•
Access to configurations on the control panel
•
Access to power cycle the MFP, to initiate cold resets, and to change other configurations
•
Access to removable storage devices such as hard drives and memory cards
•
Access to input trays, output trays, and automatic document feeder trays where hardcopy
documents may be left after processing
•
Access to network cables and phone lines connected to the MFP
•
Access to digital sending services and features
•
Access to stored print jobs (depending on settings)
•
Access to copy features (unauthorized overuse of resources such as toner and paper)
You can help minimize all of these risks by placing the MFPs in access-controlled locations.
You can control access to the MFP internal hardware (hard drives, Compact Flash cards, and
formatter board) using hardware locks. Use a lock, such as a Kensington Lock, as recommended in
the MFP User Guide.
If you have purchased the EIO version of the HP Secure Hard Disk (J8019A), you can also use a
Kensington style lock (cabled or cable-less) to protect the disk from being unscrewed and removed
from the device. If you use a cabled Kensington lock, you can even secure the device to a
stationary object to avoid someone from stealing the MFP.

Chapter 9: Appendix 1: Glossary of Terms and Acronyms
The following table lists terms and acronyms found in this checklist:
Term
Description
ACL
Access Control List. The ACL restricts network access to the MFP by
allowing only those IP addresses or subnets that are listed in it.
Analog fax
Analog fax is fax functions via telephone lines. The fax module is
available in most HP MFP bundles and it is covered in this checklist.
MFPs are also capable of sending fax via LAN fax or internet fax
using additional solutions on the network. LAN fax and Internet fax are
not covered in this checklist.
Bootloader
The bootloader is the program that starts up an MFP when the power
is turned on. It loads the MFP operating systems and the
configurations. The bootloader includes settings, such as cold
resetting, that are accessible via special codes (not covered in this
checklist). These settings are protected by the bootloader password.
Control Panel
The control panel is the display and the buttons on the front of an MFP.
Digital sending
Digital sending is a function of the MFP that sends scanned documents
to email destinations or to network destinations. Faxing is also
considered digital sending, but it is separate from the network
functions.
DSS
Digital Send Service. DSS is an HP solution to enhance MFP digital
sending functionality and security. For instance, it can encrypt the
contents of digital send jobs. It can be purchased and downloaded at
hp.com. DSS is useful and recommended, but it is not covered in this
checklist.
EWS
Embedded Web Server. The EWS is a web page built into an MFP to
provide status and configuration settings. The EWS is accessible over
network lines using any Web browser connecting to the MFP network
IP address.
Firmware
Firmware is the program that operates the MFP. It controls all functions
of the MFP. Firmware can be upgraded as new versions become
available. New firmware is available by searching for it by product at
hp.com. This checklist assumes that each MFP is upgraded with the
latest firmware.
Formatter
The formatter is the main circuit board of the MFP. It is similar to the
motherboard of a PC. The formatter accommodates the MFP hard
drive, the Compact Flash cards, the Jetdirect card, the CPU, the
analog fax accessory card, and the DC Controller, which is the power
supply for the MFP. The formatter also accommodates accessories such
as wireless cards.
Since the formatter is removable (using common tools), it includes the
capability to be locked using devices such as Kensington locks.
