Introduction
The Endpoint Security Suite Enterprise for Mac Administrator Guide provides the information needed to deploy and install the client software.
Topics:
•
•
•
Overview
Endpoint Security Suite Enterprise for Mac offers Advanced Threat Prevention at the operating system and memory layers and encryption, all centrally-managed from the Dell Server. With centralized management, consolidated compliance reporting, and console threat alerts, businesses can easily enforce and prove compliance for all of their endpoints. Security expertise is built in with features such as pre-defined policy and report templates, to help businesses reduce IT management costs and complexity.
● Endpoint Security Suite Enterprise for Mac - a suite of software for client encryption of data and Advanced Threat
Prevention.
●
- used to distribute policies
●
Security Server - used for client encryption software activations
● Security Management Server or Security Management Server Virtual - provides centralized security policy administration, integrates with existing enterprise directories and creates reports. For the purposes of this document, both Servers are cited as Dell Server, unless a specific version needs to be cited (for example, a procedure is different using Security Management
Server Virtual).
These Dell components inter-operate seamlessly to provide a secure mobile environment without detracting from the user experience.
Endpoint Security Suite Enterprise for Mac has two .dmg files - one for the Encryption client and one for Advanced Threat
Prevention. You can install both or one only.
FileVault Encryption
Dell Encryption can manage Mac FileVault full disk encryption. The Dell Volume Encryption policy must be set to On for encryption to take place and for other policy settings to function. For information on additional policies, see AdminHelp .
Only FileVault encryption is supported, which Endpoint Security Suite Enterprise will manage. If a computer has the Dell Volume
Encryption policy set to On and Encrypt Using FileVault for Mac set to Off , a policy conflict message displays on the Encryption client. The administrator must set both policies to On .

Install/Upgrade the Encryption Client
This section guides you through the the Encryption client for Mac installation/upgrade and activation process.
There are two methods to install/upgrade the Encryption client for Mac. Select one of the following:
●
Interactive Installation/Upgrade and Activation
- This method is the easiest method to install or upgrade the client software package. However, this method does not allow any customizations. If you intend to use Boot Camp or a version of operating system that is not yet fully supported by Dell (through .plist modification), you must use the command line installation/ upgrade method. For information about using Boot Camp, see
.
●
administrators experienced with command line syntax. If you intend to use Boot Camp or a version of operating system that is not yet fully supported by Dell (through .plist modification), you must use this method to install or upgrade the client software package. For information about using Boot Camp, see
For more information on the Installer Command options, see the Mac OS X Reference Library at http://developer.apple.com.
Dell highly recommends using remote deployment tools, such as Apple Remote Desktop, to distribute the client installation package.
NOTE:
Apple often releases new versions of operating systems between releases of Endpoint Security Suite Enterprise for Mac.
To support as many customers as possible, a modification of the com.dell.ddp.plist file is allowed to support these cases.
Testing of these versions begins as soon as Apple releases a new version, to ensure that they are compatible with the
Encryption client for Mac.
Prerequisites
Dell recommends that IT best practices are followed during the deployment of client software. This includes, but is not limited to, controlled test environments for initial tests and staggered deployments to users.
Before beginning this process, ensure the following prerequisites are met:
● Ensure that the Dell Server and its components are already installed.
If you have not yet installed the Dell Server, follow the instructions in the appropriate guide below.
Security Management Server Installation and Migration Guide
Security Management Server Virtual Quick Start Guide and Installation Guide
● Ensure that you have the Security Server and Policy Proxy URLs handy. Both are needed for client software installation and activation.
Tasks for the Encryption Client 11
● If your deployment uses a non-default configuration, ensure that you know the port number for the Security Server. It is needed for client software installation and activation.
● Ensure that the target computer has network connectivity to the Security Server and Policy Proxy.
● Ensure that you have a domain user account in the Active Directory installation configured for use with the Dell Server. The domain user account is used for client software activation. Configuring Mac endpoints for domain (network) authentication is not required.
Before setting encryption policies, the Dell Volume Encryption policy must be On.
. Be sure that you understand the Encrypt
Using FileVault for Mac and Volumes Targeted for Encryption policies.
For more information about encryption policies, see Mac Encryption > Dell Volume Encryption
.
Interactive Installation or Upgrade
To install or upgrade and activate the client software, follow the steps below. You must have an administrator account to perform these steps.
Interactive Installation

If an enterprise uses removable media with macOS 10.15 and higher, users must enable full disk access for external media. For
more information, see Enable Full Disk Access for Removable Media
.
Command Line Installation/Upgrade
To install the client software using the command line, follow these steps.
Command Line Installation
1. From the Dell installation media, mount the Dell-Encryption-Enterprise-<version>.dmg file.
2. Copy the Install Dell Endpoint Security Suite Enterprise package and the com.dell.ddp.plist
file to the local drive.
3. In the Management Console, modify the following policies if needed. Policy settings override .plist file settings. Use .plist
settings if policies do not exist in the Management Console.
● No Auth User List - In some cases, you may want to edit this policy so that specified users or classes of users do not have to activate against the Dell Server. For example, in an educational facility, teachers would be prompted to activate their computer against the Dell Server, but individual students using lab computers would not. The lab administrator could use this policy and the account running the client tool so that student users could log in without being prompted to activate. For information on the client tool, see
. If an enterprise needs to know which user account is associated with each Mac computer, all users must activate against the Dell Server, so that enterprise would not edit this property. However, if a user wants to provision Encryption External Media, the user must be authenticated against the
Dell Server.
4. Open the .plist file and edit any additional placeholder values:
NOTE:
Apple often releases new versions of operating systems between releases of Endpoint Security Suite Enterprise for Mac.
To support as many customers as possible, Dell allows a modification of the .plist file to support these cases. As soon as
Apple releases a new version, Dell begins testing these versions to ensure that they are compatible with the Encryption client for Mac.

FileVault Encryption of an Unencrypted Volume
With FileVault encryption, an additional unnamed user displays in the PBA. Do not delete this user as it allows the Dell Server to enforce policy on the device. If the PBA user is removed, the user will need to take action to begin policy-mandated decrypts.
1. After installation and activation, you must log into the account you want to boot from after FileVault encryption is active.
2. Wait for validation of the drive and verification of the volume to complete.
3. Enter the password for the account.
NOTE:
If you allow this dialog to time out, you must reboot or log in for the password dialog to display again.
4. Click OK .

If the account the user was logged into is a non-mobile network account, a dialog displays. After the boot drive is encrypted, the drive can be booted only by the user who was logged in during FileVault initialization.
This account must be a local or network mobile account. To change non-mobile network accounts to mobile accounts, go to
System Preferences > Users and Groups . Do one of the following:
● Make the account a mobile account.
OR
● Log into a local account and initialize FileVault from that location.
6. Click OK .
7. After encryption preparation is complete, restart the computer.
NOTE:
Depending on the User Experience policies set in the Management Console, the client software may prompt the user to restart the computer.
8. After the computer restarts, it must be connected to the network for the client software to escrow recovery information to the Dell Server.
The client software can begin and complete the encryption process, as well as report encryption status to the Management
Console, all before user login. This allows you to enforce compliance across all Mac computers without requiring user interaction.
Tasks for the Encryption Client 21
Modify Policy to Add FileVault Users
FileVault secures the data on a disk by automatically encrypting it. In a managed FileVault boot volume, to allow multiple users to unlock the disk, you can modify a policy in the Management Console and use your dictionary of OpenDirectory record names and values to then allow users to add themselves to the FileVault disk.
1. In the Management Console's advanced Mac Global Settings policies, scroll to the FileVault 2 PBA User List policy.
2. In the FileVault 2 PBA User List policy field, enter a rule that matches the users you plan to specify. For example, matching
<string>*</string> for any key should match all users that the bound OpenDirectory server has.
Tags are case sensitive, and the entire value must be properly formed as dictionary and array elements in a property list.
Dictionary keys are AND'd together. Array values are or'd together so matching any element in an array matches for the entire array.
NOTE:
If a rule is improperly formed, an error displays in the Dell Encryption Enterprise > Preferences tab.
The following <dict> lists examples for two keys:
<dict>
<key>dsAttrTypeStandard:AuthenticationAuthority</key>
<array>
<string>;Kerberosv5;;user1@LKDC:*</string>
<string>;Kerberosv5;;user2@LKDC:*</string>
<string>;Kerberosv5;;user3@LKDC:*</string>
<string>;Kerberosv5;;z*@LKDC:*</string>
</array>
<key>dsAttrTypeStandard:NFSHomeDirectory</key>
<string>/Users/*</string>
</dict>
● The sample AuthenticationAuthority key entries specify a pattern of user1 , user2 , and user3 or any user id that begins with z . To view the dialog that provides the correct syntax for each user, press the Control-Option-Command keys on the client. Copy the syntax for the user, and paste it to the Management Console.
NOTE:
For this example, trailing asterisks represent the latter part of the authentication authority records. Typically, to avoid under-specifying, include the complete record instead of a trailing asterisk because the asterisk matches any information after the colon in the OpenDirectory record.
● The NFSHomeDirectory key requires that any user passing the first key must also have a home directory in /Users/ .
NOTE:
You must create the home folder if one does not exist for a user.
3. Reboot the computers.
4. Notify users to enable FileVault booting for their user account. The user must have a local or mobile account. Network accounts are automatically converted to mobile accounts.
For a user to enable their FileVault account:
1. Launch System Preferences , and click Dell Encryption Enterprise .
2. Click the System Volumes tab.
3. Control-click the System Volume drive, and select Add FileVault users to FileVault Booting .
4. In Search , enter a user's name or scroll down. User accounts display only if they meet the criteria set by policy.
For local and mobile users, an Enable User button displays.
For network users, a Convert & enable user button displays.
NOTE:
A green indicator displays next to user accounts that can boot FileVault.
5. Click Enable User or Convert & enable user .
6. Enter the password for the selected account and click OK . A progress indicator displays.
7. After a success dialog, click Done .

Assume Management of an Existing FileVault-Encrypted Volume
If the computer already has a FileVault-encrypted volume and FileVault encryption is enabled in the Management Console, Dell
Encryption can assume management of the volume.
If Dell Encryption detects that the boot volume is already encrypted, the Dell Encryption Enterprise dialog displays. To allow Dell
Encryption to assume management of the volume, follow these steps.
1. Select either Personal Recovery Key
or
Bootable Account Credentials .
NOTE:
For macOS High Sierra and Apple File System (APFS), you must select Bootable Account Credentials .
● Personal Recovery Key - if you have the personal recovery key you received when the drive was FileVaultencrypted.
a. Enter the key.
If a user does not have the existing key, they can request it from the administrator.
b. Click OK .
NOTE:
After the assumption process is complete, a new personal recovery key is generated and escrowed. The previous recovery key is invalidated and removed.
● Bootable Account Credentials - if you have the username and password of an account that is currently authorized to boot from the volume.
a. Enter the user name and password.
b. Click OK .
2. When a dialog displays indicating that Dell now manages encryption of the volume, click OK .
If Dell Encryption detects that a non-boot volume is already encrypted, a passphrase prompt displays.
3. (FileVault-encrypted non-boot volumes only) To allow Dell Encryption to assume management of the volume, enter the passphrase to access the volume. This is the password that was assigned to the volume when it was originally FileVaultencrypted.
Once Dell manages the volume's encryption, the old password is no longer valid. Your Dell administrator can retrieve a recovery key for your volume in the event that you should need recovery assistance.
If you choose not to enter the password, the volume's contents are accessible and are encrypted with FileVault but the encryption is not managed by Dell.
NOTE:
In the Management Console, the administrator can see that the Dell Server now manages the endpoint.
Recycling FileVault Recovery Keys
If you have security issues with a recovery bundle or if a volume or keys are compromised, you can recycle the key material for that volume.
You can recycle keys for boot and non-boot drives on Mac OS X.
To recycle the key material:
1. Download a recovery bundle from the Management Console and copy it to the computer's desktop.
2. Launch System Preferences and click Dell Encryption Enterprise .
3. Click the System Volumes tab.
4. Drag the recovery bundle from step 1 to the appropriate partition.
A dialog prompts you to cycle the FileVault keys.
5. Click OK .
A dialog confirms success for cycling keys.
Tasks for the Encryption Client 23
6. Click OK .
NOTE:
Keys in the recovery bundle for this drive are now obsolete. You must download a new recovery bundle from the
Management Console.
User Experience
For maximum security, the client software disables the Automatic Login feature of Mac OS X computers.
Additionally, the client software automatically enforces the Mac OS X feature require password after sleep or screen saver begins . Also, a configurable amount of time is allowed in sleep/screen saver mode before enforcing authentication. The client software allows a user to set a value up to five minutes before authentication is enforced.
Users can use the computer normally as the encryption sweep progresses. All data on the currently booted system volume is being encrypted, including the operating system, while the operating system continues to operate.
If the computer is restarted or enters system sleep, the encryption sweep pauses and then automatically resumes after the restart or wake.
The client software does not support the use of hibernation images, which the Mac OS X Safe Sleep feature uses to wake the computer if the battery is fully discharged during sleep.
To reduce user impact, the client software automatically updates the system sleep mode to disable hibernation and enforces this setting. The computer can still enter sleep, but the current system state is maintained only in memory. Therefore, the computer is fully restarted if completely shut down during sleep, which could occur if the battery runs down or is replaced.
Copy allowlist rule
A hidden menu item allows a user to copy a allowlist rule for removable media.
1. Launch System Preferences and click Dell Encryption Enterprise .
2. Select the Removable Media tab.
3. Right-click a drive row, and simultaneously press the command key.
A hidden menu item displays.
4. Click Copy allowlist rule for the current removable media. The allowlist rule is copied to the Clipboard.
5. Access the Clipboard, copy the allowlist rule, and send it to your administrator.
If the Mac Media Encryption policy is toggled On , data is encrypted, including Thunderbolt drives.
To exclude a device or group of devices to prevent writing encrypted data to the Thunderbolt drive or to Encryption External
Media, use the allowlist rule to modify the values.
Use the complete rule to specify a particular drive for allowlisting, for example: bus=USB;fstype=HFS+;tbolt=0;size=4006608896;USBPRODUCTNUM=5669;USBPRODNAME=DT101
II;USBVENDORNAME=Kingston;USBVENDORNUM=2385;USBSERNUM=001CC0EC3447AA308699119F
NOTE:
Be sure to replace the sample values with the information for your drive.
NOTE:
You must enable HFS Plus. See Enable HFS Plus
.
To exclude SATA devices from Mac Media Encryption policy enforcement when connected via Thunderbolt: tbolt=1;bus=SATA
You can also allowlist or exclude media from Encryption External Media based on:
● Media size
Allowlist rule to exclude large media from Encryption External Media protection:
24 Tasks for the Encryption Client
size <op> <size specifier>
<op> can be =, <=, >=, <, >
<size specifier> is of the form decimal integer with an optional suffix from {K, M, G, T} aligned on 1000, not 1024. For example, to exclude media or a drive greater than 500000000 bytes from Encryption External Media, use one of these: size >= 500000000 size >= 500000K size >= 500M
● File system type
Allowlist rule: fstype=<fstype>
<fstype> can be ExFAT, FAT, or HFS+
To exclude both, here is an example for 1TB and greater HFS+ media: size>=1T;fstype=HFS+
Recovery
Occasionally, you may need access to data on encrypted disks. As a Dell administrator, you can access encrypted disks without decrypting them, saving you valuable time.
You might need to access a user's encrypted data for many reasons, but a few common use cases are as follows:
● Someone leaves the company, and no one knows the password.
● A user cannot recall the password.
This section guides you through the process of using
FileVault Recovery when FileVault encryption is on the endpoint to be
recovered. FileVault can be used with the Encryption client running on macOS Sierra 10.12.6. FileVault recovery is also used on
Fusion Drives.
Mount Volume
Prerequisites
● An unencrypted external recovery volume or computer to run the recovery utility
● A FireWire or Thunderbolt cable, depending on your hardware
● The Device ID/Unique ID of the computer targeted for recovery - In most cases, you can find the computer targeted for recovery in the Management Console by searching for the owner's user name and viewing the devices encrypted for that user. The format of the Unique ID/Device ID is "John Doe's MacBook.Z4291LK58RH".
● The Dell installation media

or
Boot the computer targeted for recovery into Target Disk Mode. You can accomplish this by either launching the Startup
Disk pane in System Preferences and clicking Target Disk Mode , or by holding down the T key while you restart this computer.
NOTE:
Firmware password protection blocks the ability to use the T key at startup to enter Target Disk Mode. More information about Target Disk Mode is available from Apple at http://support.apple.com/kb/HT1661.
Now connect this computer to the host computer that will perform the recovery operation using a FireWire or Thunderbolt cable, depending on your hardware.
8. Mount the Dell-Encryption-Enterprise-<version>.dmg.
NOTE:
The Recovery Utility must be the same or newer version than the version of client software installed on the computer targeted for recovery.
9. Select the volume or drive that needs recovery and click Continue .
Selecting the drive recovers all volumes on the drive at once.
10. Select the recovery bundle (saved in step 6 ) and click
Open .
11. Click Close .
You can now open a Finder window and access data on the encrypted volume as you would a normal volume. All data is transparently encrypted and decrypted as files are transferred between the volumes.
FileVault Recovery
Recovery of a managed FileVault-encrypted volume is dictated by Apple and is automated where possible but requires a few more steps.
The Dell Recovery Utility simplifies the operation of Apple's recovery tools with scripts to assist with mounting a volume or, in some cases, decrypting it. FileVault recovery functionality is determined by the operating system installed on the Recovery HD and the paired target partition.
A FileVault-encrypted volume can be recovered only from a Recovery HD partition that is written to all disk drives running
Mac OS X 10.9.5 or later. This requirement eliminates the possibility of performing a recovery operation directly from the Dell
Recovery Utility.
Two recovery methods exist, based on whether the FileVault recovery key is a personal or institutional recovery key. One valid recovery key always exists. If a personal recovery key exists, Dell recommends that you use the most recent entry for that key.
If that key does not work, then use the institutional recovery keychain.
●
- Existing FileVault encryption is managed by the Dell Server. If the most recent entry in the recovery
bundle contains a RecoveryKey entry, follow the Personal Recovery Key
steps. Here is a RecoveryKey example:
RecoveryKey</key><string>C73W-CX2B-ANFY-HH3K-RLRE-LVAK</string>
●
(rarely used) - This recovery method is based on use of a FileVault institutional recovery key.

<key>EMSHFSPlusOptIn</key>
<true/>
NOTE:
Dell recommends testing this configuration before introducing it into the production environment.
HFS Plus does not support:
● Versioning - Existing versioning data is removed from the disk.
● Hard links - During an encryption sweep of the removable media, the file is not encrypted. A dialog recommends ejecting the media.
● Media containing Time Machine backups:
○ Media recognizably used by the computer as a Time Machine backup destination is automatically allowlisted to allow backups to continue.
○ All other removable media with Time Machine backups is based on policy governing unprovisioned media and unprotected media. See EMS Access to unShielded Media and EMS Block Access to UnShieldable Media policies.
NOTE:
For a new drive that does not yet have backups, the user must copy their allowlist rule and send you the rule to specify their Time Machine drive for allowlisting. See
.
Encryption External Media and Policy Updates
On the system where the removable media was provisioned (or recovered), policies are updated on the removable media at mount time.
Encryption Exceptions
Extended attributes are not encrypted on removable media.
Errors on the Removable Media Tab
● On an unshielded computer, do not replace an encrypted file with a decrypted version of the file. Later, this could prevent decryption. This may also display as an error on the Removable Media tab.
● If an end-of-file marker is invalidated, for example if a file is overwritten with new content outside of Encryption External
Media control, and then you mount in Encryption External Media, an end-of-file error displays on the Removable Media tab.
● When you convert files, the media must have more free space than the size of the largest file to be converted. If a yellow warning triangle displays in the Removable Media status area, click it. If a message indicates Insufficient space , do the following:
1. Note the amount of space that must be freed on the device. The report displays a list of files and the size.

Messages display the status of the uninstallation.
The Encryption client for Mac is now uninstalled, and the computer can be used normally.
Activation as Administrator
The Client Tool offers the administrator new methods for activating the client software on a Mac computer and examining the client software. Two methods of activation are available:
● Activation using administrator credentials
● Temporary activation that emulates the user without leaving footprints on that computer.
Both methods can be used directly through a shell, or in a script.
NOTE:
Do not activate the client software on more than five computers with the same network account. Serious security vulnerabilities and degraded performance of your Dell Server could result.
Prerequisites
● The Encryption client for Mac must be installed on the remote computer.
● Do not activate through the client user interface prior to attempting to activate from a remote location.
Activate
Use this command to activate the client as administrator.
Example: client -a [email protected] password admin admin
Activate Temporarily
Use this command to activate the client without leaving footprints on the computer.
1. Open a shell or use a script to activate the client software:
client
at [email protected] password
2. Use the Client Tool to retrieve information about the client software, its policies, disk status, user account and more. For more information about the Client Tool, see

After activation, information about the client software, including policies, disk status, and user information, is also available in System Preferences in the Dell Encryption Enterprise preferences.
Encryption Client Reference
About Optional Firmware Password Protection
NOTE:
More recent Mac computers do not support Firmware Password Protection. Firmware Password Protection is supported for the following models:
● iMac10.*
● iMac11.*
● Macmini4.*
32 Tasks for the Encryption Client
● MacBook7.*
● MacBookAir2.*
● MacBookPro7.*
● MacPro5.*
● XServe3.*
For example, iMac10.1, iMac11.1 and iMac11.2 support Optional Firmware Password Protection (as indicated by the *), but iMac12.1 or later does not.
NOTE:
When the FirmwarePasswordMode key option is set to Optional , it only disables client enforcement of firmware password protection. It does not remove any existing firmware password protection. You can remove any existing firmware password using the Mac OS X Firmware Password Utility.
If you intend to use Boot Camp (see How to Enable Mac OS X Boot Camp
for instructions) on encrypted Mac computers, you must configure the client to not use firmware password protection.
Mac computers use firmware password protection to enhance access security of the computer. On Mac computers, by default, the protection is turned OFF . During client installation, whether a new installation or an upgrade from an earlier client version, you have the ability to edit the existing com.dell.ddp.plist file to allow the FirmwarePasswordMode key to be set to either
Required or Optional . The Required option is the default setting that enforces firmware password protection, while the Optional setting causes the firmware password to not be enforced. Following the installation or upgrade, the client evaluates the modified installer com.dell.ddp.plist file during restart.
NOTE:
To prevent users from changing the computer's security posture, the client does not accept changes to the
FirmwarePasswordMode key after installing the client software.
You can change the value of this key after installation or upgrade by initiating a disk decryption process, and then re-enabling encryption.
For Mac OS X firmware password protection to be required , follow normal client installation/upgrade procedures outlined in
Install/Upgrade the Encryption Client for Mac
.
Using Boot Camp
Mac OS X Boot Camp Support
NOTE:
When using Boot Camp, Dell Encryption Enterprise does not encrypt the Windows operating system. Also, if two or more bootable macOS partitions exist on the device, Encryption Enterprise encrypts only the primary volume.
Boot Camp is a utility included with Mac OS X that assists you in installing Windows on Mac computers in a dual-boot configuration. Boot Camp is supported with the following Windows operating systems:
● Windows 7 and 7 Home Premium, Professional, and Ultimate (64-bit)
● Windows 8.1 and 8.1 Pro (64-bit)
NOTE:
Windows 7 is Boot Camp 4 or 5.1. Windows 8.1 and higher is Boot Camp 5.1 only.
To use Endpoint Security Suite Enterprise for Windows in Boot Camp on a computer with Endpoint Security Suite Enterprise
for instructions.
NOTE:
If your Windows partition is a candidate for Encryption External Media, be sure to allowlist it or it will be encrypted. See
.
NOTE:
Tasks for the Encryption Client 33
You must ensure Windows is installed before deploying client policies enabling encryption. After the client begins the encryption process, it disallows disk partition operations required by Boot Camp.
Recovery of Endpoint Security Suite Enterprise for Windows on Boot Camp
To recover Endpoint Security Suite Enterprise for Windows running in a Boot Camp volume, you must also create a Boot Camp volume on an external drive.
Prerequisites
● An external bootable drive
● The Device ID/Unique ID of the computer targeted for recovery. In most cases, you can find the computer targeted for recovery in the Management Console by searching for the owner's user name and viewing the devices encrypted for that user. The format of the Device ID/Unique ID is "John Doe's MacBook.Z4291LK58RH".
