The ASA FirePOWER Module

The ASA FirePOWER module supplies next-generation firewall services, including Next-Generation

Intrusion Prevention System (NGIPS), Application Visibility and Control (AVC), URL filtering, and

Advanced Malware Protection (AMP).You can use the module in single or multiple context mode, and in routed or transparent mode.

The module is also known as ASA SFR.

Although the module has a basic command line interface (CLI) for initial configuration and troubleshooting, you configure the security policy on the device using a separate application, FireSIGHT

Management Center, which can be hosted on a separate FireSIGHT Management Center appliance or as a virtual appliance running on a VMware server. (FireSIGHT Management Center is also known as

Defense Center.)

For ASA FirePOWER running on ASA 5506-X devices, you can optionally configure the device using

ASDM rather than FireSIGHT Management Center.

How the ASA FirePOWER Module Works with the ASA

You can configure your ASA FirePOWER module using one of the following deployment models:

Cisco ASA Series Firewall ASDM Configuration Guide

16-1

Chapter 16 ASA FirePOWER (SFR) Module

The ASA FirePOWER Module

•

•

•

Inline mode—In an inline deployment, the actual traffic is sent to the ASA FirePOWER module, and the module’s policy affects what happens to the traffic. After dropping undesired traffic and taking any other actions applied by policy, the traffic is returned to the ASA for further processing and ultimate transmission.

Inline tap monitor-only mode (ASA inline)—In an inline tap monitor-only deployment, a copy of the traffic is sent to the ASA FirePOWER module, but it is not returned to the ASA. Inline tap mode lets you see what the ASA FirePOWER module would have done to traffic, and lets you evaluate the content of the traffic, without impacting the network. However, in this mode, the ASA does apply its policies to the traffic, so traffic can be dropped due to access rules, TCP normalization, and so forth.

Passive monitor-only (traffic forwarding) mode—If you want to prevent any possibility of the ASA with FirePOWER Services device impacting traffic, you can configure a traffic-forwarding interface and connect it to a SPAN port on a switch. In this mode, traffic is sent directly to the ASA

FirePOWER module without ASA processing. The traffic is “black holed,” in that nothing is returned from the module, nor does the ASA send the traffic out any interface. You must operate the

ASA in single context transparent mode to configure traffic forwarding.

Be sure to configure consistent policies on the ASA and the ASA FirePOWER. Both policies should reflect the inline or monitor-only mode of the traffic.

The following sections explain these modes in more detail.

ASA FirePOWER Inline Mode

In inline mode, traffic goes through the firewall checks before being forwarded to the ASA FirePOWER module. When you identify traffic for ASA FirePOWER inspection on the ASA, traffic flows through the ASA and the module as follows:

1.

Traffic enters the ASA.

2.

3.

4.

5.

Incoming VPN traffic is decrypted.

Firewall policies are applied.

Traffic is sent to the ASA FirePOWER module.

The ASA FirePOWER module applies its security policy to the traffic, and takes appropriate actions.

6.

7.

Valid traffic is sent back to the ASA; the ASA FirePOWER module might block some traffic according to its security policy, and that traffic is not passed on.

Outgoing VPN traffic is encrypted.

8.

Traffic exits the ASA.

The following figure shows the traffic flow when using the ASA FirePOWER module in inline mode. In this example, the module blocks traffic that is not allowed for a certain application. All other traffic is forwarded through the ASA.

The ASA FirePOWER Module

Note If you have a connection between hosts on two ASA interfaces, and the ASA FirePOWER service policy is only configured for one of the interfaces, then all traffic between these hosts is sent to the ASA

FirePOWER module, including traffic originating on the non-ASA FirePOWER interface (because the feature is bidirectional).

ASA FirePOWER Inline Tap Monitor-Only Mode

This mode sends a duplicate stream of traffic to the ASA FirePOWER module for monitoring purposes only. The module applies the security policy to the traffic and lets you know what it would have done if it were operating in inline mode; for example, traffic might be marked “would have dropped” in events.

You can use this information for traffic analysis and to help you decide if inline mode is desirable.

Note You cannot configure both inline tap monitor-only mode and normal inline mode at the same time on the

ASA. Only one type of security policy is allowed. In multiple context mode, you cannot configure inline tap monitor-only mode for some contexts, and regular inline mode for others.

The following figure shows the traffic flow when operating in inline tap mode.

ASA FirePOWER Passive Monitor-Only Traffic Forwarding Mode

If you want to operate the ASA FirePOWER module as a pure Intrusion Detection System (IDS), where there is no impact on the traffic at all, you can configure a traffic forwarding interface. A traffic forwarding interface sends all received traffic directly to the ASA FirePOWER module without any ASA processing.

The module applies the security policy to the traffic and lets you know what it would have done if it were operating in inline mode; for example, traffic might be marked “would have dropped” in events. You can use this information for traffic analysis and to help you decide if inline mode is desirable.

Traffic in this setup is never forwarded: neither the module nor the ASA sends the traffic on to its ultimate destination. You must operate the ASA in single context and transparent modes to use this configuration.

The following figure shows an interface configured for traffic-forwarding. That interface is connected to a switch SPAN port so the ASA FirePOWER module can inspect all of the network traffic. Another interface sends traffic normally through the firewall.

The ASA FirePOWER Module

ASA FirePOWER Management Access

There are two separate layers of access for managing an ASA FirePOWER module: initial configuration

(and subsequent troubleshooting) and policy management.

•

Initial Configuration, page 16-5

•

Policy Configuration and Management, page 16-5

Initial Configuration

For initial configuration, you must use the CLI on the ASA FirePOWER module. For information on the default management addresses, see

Defaults for ASA FirePOWER, page 16-7

.

To access the CLI, you can use the following methods:

• ASA 5585-X (hardware module):

–

–

ASA FirePOWER console port—The console port on the module is a separate external console port.

ASA FirePOWER Management 1/0 interface using SSH—You can connect to the default IP address or you can use ASDM to change the management IP address and then connect using

SSH. The management interface on the module is a separate external Gigabit Ethernet interface.

Note You cannot access the ASA FirePOWER hardware module CLI over the ASA backplane using the session command.

• All other models (software module):

–

–

ASA session over the backplane—If you have CLI access to the ASA, then you can session to the module and access the module CLI.

ASA FirePOWER Management 0/0 interface using SSH (Management 1/1 for the

5506-X)—You can connect to the default IP address or you can use ASDM to change the management IP address and then connect using SSH. The ASA FirePOWER management interface shares the management interface with the ASA. Separate MAC addresses and IP addresses are supported for the ASA and ASA FirePOWER module. You must perform configuration of the ASA FirePOWER IP address within the ASA FirePOWER operating system (using the CLI or ASDM). However, physical characteristics (such as enabling the interface) are configured on the ASA. You can remove the ASA interface configuration

(specifically the interface name) to dedicate this interface as an ASA FirePOWER-only interface. This interface is management-only.

Policy Configuration and Management

After you perform initial configuration, configure the ASA FirePOWER security policy using

FireSIGHT Management Center (for all models) or ASDM (for 5506-X). Then configure the ASA policy for sending traffic to the ASA FirePOWER module using ASDM or Cisco Security Manager.

Cisco ASA Series Firewall ASDM Configuration Guide

Chapter 16 ASA FirePOWER (SFR) Module

Licensing Requirements for the ASA FirePOWER Module

Compatibility with ASA Features

The ASA includes many advanced application inspection features, including HTTP inspection.

However, the ASA FirePOWER module provides more advanced HTTP inspection than the ASA provides, as well as additional features for other applications, including monitoring and controlling application usage.

To take full advantage of the ASA FirePOWER module features, use the following guidelines for traffic that you send to the ASA FirePOWER module:

•

•

Do not configure ASA inspection on HTTP traffic.

Do not configure Cloud Web Security (ScanSafe) inspection. If you configure both ASA

FirePOWER inspection and Cloud Web Security inspection for the same traffic, the ASA only performs ASA FirePOWER inspection.

•

•

Other application inspections on the ASA are compatible with the ASA FirePOWER module, including the default inspections.

Do not enable the Mobile User Security (MUS) server; it is not compatible with the ASA

FirePOWER module.

Licensing Requirements for the ASA FirePOWER Module

The ASA FirePOWER module and FireSIGHT Management Center require additional licenses, which need to be installed in the module itself rather than in the context of the ASA. The ASA itself requires no additional licenses.

See the Licensing chapter of the FireSIGHT System User Guide or the online help in FireSIGHT

Management Center for more information.

Guidelines for ASA FirePOWER

Failover Guidelines

Does not support failover directly; when the ASA fails over, any existing ASA FirePOWER flows are transferred to the new ASA. The ASA FirePOWER module in the new ASA begins inspecting the traffic from that point forward; old inspection states are not transferred.

You are responsible for maintaining consistent policies on the ASA FirePOWER modules in the high-availability ASA pair (using FireSIGHT Management Center) to ensure consistent failover behavior.

ASA Clustering Guidelines

Does not support clustering directly, but you can use these modules in a cluster. You are responsible for maintaining consistent policies on the ASA FirePOWER modules in the cluster using FireSIGHT

Management Center. Do not use different ASA-interface-based zone definitions for devices in the cluster.

Model Guidelines

• For ASA model software and hardware compatibility with the ASA FirePOWER module, see

ASA Compatibility .

Cisco

Cisco ASA Series Firewall ASDM Configuration Guide

Chapter 16 ASA FirePOWER (SFR) Module

Defaults for ASA FirePOWER

• For the 5512-X through ASA 5555-X, you must install a Cisco solid state drive (SSD). For more information, see the ASA 5500-X hardware guide. (The SSD is standard on the 5506-X.)

Additional Guidelines and Limitations

• See

Compatibility with ASA Features, page 16-6

.

•

•

You cannot change the software type installed on the hardware module; if you purchase an ASA

FirePOWER module, you cannot later install other software on it.

You cannot configure both normal inline mode and inline tap monitor-only mode at the same time on the ASA. Only one type of security policy is allowed. In multiple context mode, you cannot configure inline tap monitor-only mode for some contexts, and regular inline mode for others.

Configure the ASA FirePOWER Module

Configuring the ASA FirePOWER module is a process that includes configuration of the ASA

FirePOWER security policy on the ASA FirePOWER module and then configuration of the ASA to send traffic to the ASA FirePOWER module. To configure the ASA FirePOWER module, perform the following steps:

Step 1

Step 2

Step 3

Step 4

Step 5

Connect the ASA FirePOWER Management Interface, page 16-8 . Cable the ASA FirePOWER

management interfaces and optionally, the console interface.

(If necessary.) Install or Reimage the Software Module, page 16-11 . Skip this step if you purchased a

model with the software module pre-installed.

(If necessary.) Change the ASA FirePOWER Management IP Address, page 16-14 . This might be

required for initial SSH access.

Configure Basic ASA FirePOWER Settings at the ASA FirePOWER CLI, page 16-15

. You do this on the ASA FirePOWER module.

(Optional for ASA 5506-X.) Add ASA FirePOWER to the FireSIGHT Management Center, page 16-16 .

This identifies the FireSIGHT Management Center that will manage the device. If you do not configure a FireSIGHT Management Center for the 5506-X, you can manage the module using ASDM.

Connect the ASA FirePOWER Management Interface

In addition to providing management access to the ASA FirePOWER module, the ASA FirePOWER management interface needs access to an HTTP proxy server or a DNS server and the Internet for signature updates and more. This section describes recommended network configurations. Your network may differ.

ASA 5585-X (Hardware Module)

The ASA FirePOWER module includes a separate management and console interface from the ASA. For initial setup, you can connect with SSH to the ASA FirePOWER Management 1/0 interface using the default IP address. If you cannot use the default IP address, you can either use the console port or use

ASDM to change the management IP address so you can use SSH. (See

Change the ASA FirePOWER

Cisco ASA Series Firewall ASDM Configuration Guide

Chapter 16 ASA FirePOWER (SFR) Module

Configure the ASA FirePOWER Module

Install or Reimage the Software Module

If you purchase the ASA with the ASA FirePOWER module, the module software and required solid state drives (SSDs) come pre-installed and ready to configure. If you want to add the ASA FirePOWER software module to an existing ASA, or need to replace the SSD, you need to install the ASA

FirePOWER boot software, partition the SSD, and install the system software according to this procedure.

Reimaging the module is the same procedure, except you should first uninstall the ASA FirePOWER module. You would reimage a system if you replace an SSD.

For information on how to physically install the SSD, see the ASA hardware guide.

Before You Begin

• The free space on flash (disk0) should be at least 3GB plus the size of the boot software.

• In multiple context mode, perform this procedure in the system execution space.

• You must shut down any other software module that you might be running; the device can run a single software module at a time. You must do this from the ASA CLI. For example, the following commands shut down and uninstall the IPS software module, and then reload the ASA; the commands to remove the CX module are the same, except use the cxsc keyword instead of ips.

hostname# sw-module module ips shutdown hostname# sw-module module ips uninstall hostname# reload

•

•

•

If you have an active service policy redirecting traffic to an IPS or CX module, you must remove that policy. For example, if the policy is a global one, you could use no service-policy ips_policy

global. If the service policy includes other rules you want to maintain, simply remove the redirection command from the relevant policy map, or the entire traffic class if redirection is the only action for the class. You can remove the policies using CLI or ASDM.

When reimaging the module, use the same shutdown and uninstall commands to remove the old image. For example, sw-module module sfr uninstall.

Obtain both the ASA FirePOWER Boot Image and System Software packages from Cisco.com.

Procedure

Step 1

Step 2

Download the boot image to the device. Do not transfer the system software; it is downloaded later to the SSD. You have the following options:

•

•

ASDM—First, download the boot image to your workstation, or place it on an FTP, TFTP, HTTP,

HTTPS, SMB, or SCP server. Then, in ASDM, choose Tools > File Management, and then choose the appropriate File Transfer command, either Between Local PC and Flash or Between Remote

Server and Flash. Transfer the boot software to disk0 on the ASA.

ASA CLI—First, place the boot image on a TFTP, FTP, HTTP, or HTTPS server, then use the copy command to download it to flash. The following example uses TFTP; replace <TFTP Server> with your server’s IP address or host name.

ciscoasa# copy tftp://<TFTP SERVER>/asasfr-5500x-boot-5.3.1-58.img disk0:/asasfr-5500x-boot-5.3.1-58.img

Download the ASA FirePOWER system software from Cisco.com to an HTTP, HTTPS, or FTP server accessible from the ASA FirePOWER management interface. Do not download it to disk0 on the ASA.

Step 3

Step 4

Step 5

Step 6

Set the ASA FirePOWER module boot image location in ASA disk0 by entering the following command: hostname# sw-module module sfr recover configure image disk0:file_path

If you get a message like “ERROR: Another service (cxsc) is running, only one service is allowed to run at any time,” it means that you already have a different software module configured. You must shut it down and remove it to install a new module as described in the prerequisites section above.

Example: hostname# sw-module module sfr recover configure image disk0:asasfr-5500x-boot-5.3.1-58.img

Load the ASA FirePOWER boot image by entering the following command: hostname# sw-module module sfr recover boot

Wait approximately 5-15 minutes for the ASA FirePOWER module to boot up, and then open a console session to the now-running ASA FirePOWER boot image. You might need to press enter after opening the session to get to the login prompt. The default username is admin and the default password is

Admin123.

Default values are inside []

Step 7

You are prompted for the following. Note that the management address and gateway, and DNS information, are the key settings to configure.

• Host name—Up to 65 alphanumeric characters, no spaces. Hyphens are allowed.

•

•

Network address—You can set static IPv4 or IPv6 addresses, or use DHCP (for IPv4) or IPv6 stateless autoconfiguration.

DNS information—You must identify at least one DNS server, and you can also set the domain name and search domain.

• NTP information—You can enable NTP and configure the NTP servers, for setting system time.

Install the System Software image using the system install command:

system install [noconfirm] url

Include the noconfirm option if you do not want to respond to confirmation messages. Use an HTTP,

HTTPS, or FTP URL; if a username and password are required, you will be prompted to supply them.

When installation is complete, the system reboots. Allow 10 or more minutes for application component installation and for the ASA FirePOWER services to start. (The show module sfr output should show all processes as Up.)

This sensor must be managed by a Defense Center. A unique alphanumeric registration key is always required. In most cases, to register a sensor

Cisco ASA Series Firewall ASDM Configuration Guide

16-13

Chapter 16 ASA FirePOWER (SFR) Module

Configure the ASA FirePOWER Module to a Defense Center, you must provide the hostname or the IP address along with the registration key.

'configure manager add [hostname | ip address ] [registration key ]'

However, if the sensor and the Defense Center are separated by a NAT device, you must enter a unique NAT ID, along with the unique registration key.

'configure manager add DONTRESOLVE [registration key ] [ NAT ID ]'

Later, using the web interface on the Defense Center, you must use the same registration key and, if necessary, the same NAT ID when you add this sensor to the Defense Center.

Step 11 (Optional for 5506-X.) Identify the FireSIGHT Management Center appliance that will manage this device using the configure manager add command.

You come up with a registration key, which you will then use in FireSIGHT Management Center when you add the device to its inventory. The following example shows the simple case. When there is a NAT boundary, the command is different; see

Add ASA FirePOWER to the FireSIGHT Management Center, page 16-16

.

> configure manager add 10.89.133.202 123456

Manager successfully configured.

Step 12

For the 5506-X, you can instead use ASDM to configure the policy on the ASA FirePOWER module.

When using ASDM, you can configure one module at a time, which is a good solution when you have a single device or very few devices. If you have a large number of devices, FireSIGHT Management Center is a better solution.

(Skip for 5506-X when using ASDM.) Log into the FireSIGHT Management Center using an HTTPS connection in a browser, using the hostname or address entered above. For example, https://DC.example.com.

Use the Device Management (Devices > Device Management) page to add the device. For more information, see the online help or the Managing Devices chapter in the FireSIGHT System User Guide.

Tip You also configure NTP and time settings through FireSIGHT Management Center. Use the

Time Synchronization settings when editing the local policy from the System > Local > System

Policy page.

Change the ASA FirePOWER Management IP Address

If you cannot use the default management IP address, then you can set the management IP address from the ASA. After you set the management IP address, you can access the ASA FirePOWER module using

SSH to perform additional setup.

If you already configured the management address during initial system setup through the ASA

FirePOWER CLI, as described in

Configure Basic ASA FirePOWER Settings at the ASA FirePOWER

CLI, page 16-15 , then it is not necessary to configure it through the ASA CLI or ASDM.

Note For a software module, you can access the ASA FirePOWER CLI to perform setup by sessioning from the ASA CLI; you can then set the ASA FirePOWER management IP address as part of setup. For a hardware module, you can complete the initial setup through the Console port.

Chapter 16 ASA FirePOWER (SFR) Module

Configure the ASA FirePOWER Module

To change the management IP address through the ASA, do one of the following. In multiple context mode, perform this procedure in the system execution space.

• In the CLI, use the following command to set the ASA FirePOWER management IP address, mask, and gateway. Use 1 for a hardware module, sfr for a software module.

session {1 | sfr} do setup host ip ip_address/mask,gateway_ip

•

For example, session 1 do setup host ip 10.1.1.2/24,10.1.1.1.

In ASDM, choose Wizards > Startup Wizard, and progress through the wizard to the ASA

FirePOWER Basic Configuration, where you can set the IP address, mask, and default gateway.

Configure Basic ASA FirePOWER Settings at the ASA FirePOWER CLI

You must configure basic network settings and other parameters on the ASA FirePOWER module before you can configure your security policy. This procedure assumes you have the full system software installed (not just the boot image), either after you installed it directly, or because it is already installed on a hardware module.

Tip This procedure also assumes that you are performing an initial configuration. During initial configuration, you are prompted for these settings. If you need to change these settings later, use the various configure network commands to change the individual settings. For more information on the

configure network commands, use the ? command for help, and see the FireSIGHT System User Guide, or the online help in FireSIGHT Management Center.

Procedure

Step 1

Step 2

Step 3

Do one of the following:

•

•

(All models.) Use SSH to connect to the ASA FirePOWER management IP address.

(Software modules only.) Open a session to the module from the ASA CLI (see the “Getting Started” chapter in the general operations configuration guide to access the ASA CLI). In multiple context mode, session from the system execution space.

hostname# session sfr

Log in with the username admin and the password Sourcefire.

Complete the system configuration as prompted.

You must first read and accept the end user license agreement (EULA). Then change the admin password, then configure the management address and DNS settings, as prompted. You can configure both IPv4 and IPv6 management addresses. The configuration is complete when you see the message that says the sensor must be managed by a FireSIGHT Management Center.

For example:

System initialization in progress. Please stand by.

You must change the password for 'admin' to continue.

Enter new password: <new password>

Confirm new password: <repeat password>

You must configure the network to continue.

You must configure at least one of IPv4 or IPv6.

Do you want to configure IPv4? (y/n) [y]: y

Do you want to configure IPv6? (y/n) [n]:

Configure IPv4 via DHCP or manually? (dhcp/manual) [manual]:

Enter an IPv4 address for the management interface [192.168.45.45]: 10.86.118.3

Enter an IPv4 netmask for the management interface [255.255.255.0]: 255.255.252.0

Enter the IPv4 default gateway for the management interface []: 10.86.116.1

Enter a fully qualified hostname for this system [Sourcefire3D]: asasfr.example.com

Enter a comma-separated list of DNS servers or 'none' []: 10.100.10.15,

10.120.10.14

Enter a comma-separated list of search domains or 'none' [example.net]: example.com

If your networking information has changed, you will need to reconnect.

For HTTP Proxy configuration, run 'configure network http-proxy'

(Wait for the system to reconfigure itself.)

This sensor must be managed by a Defense Center. A unique alphanumeric registration key is always required. In most cases, to register a sensor to a Defense Center, you must provide the hostname or the IP address along with the registration key.

'configure manager add [hostname | ip address ] [registration key ]'

However, if the sensor and the Defense Center are separated by a NAT device, you must enter a unique NAT ID, along with the unique registration key.

'configure manager add DONTRESOLVE [registration key ] [ NAT ID ]'

Later, using the web interface on the Defense Center, you must use the same registration key and, if necessary, the same NAT ID when you add this sensor to the Defense Center.

(Optional for 5506-X.) Now you must identify the FireSIGHT Management Center that will manage this device, as explained in

Add ASA FirePOWER to the FireSIGHT Management Center, page 16-16

.

Add ASA FirePOWER to the FireSIGHT Management Center

FireSIGHT Management Center, also known as Defense Center, is a separate server that manages multiple FirePOWER devices for the same or different models. FireSIGHT Management Center is ideal for managing large deployments, providing configuration consistency across your devices and efficiency in traffic analysis.

For ASA 5512-X through 5585-X, you must register the module to a FireSIGHT Management Center.

There is no other way to configure the module.

To register a device, use the configure manager add command. A unique alphanumeric registration key is always required to register a device to a FireSIGHT Management Center. This is a simple key that you specify, and is not the same as a license key.

In most cases, you must provide the FireSIGHT Management Center’s hostname or the IP address along with the registration key, for example: configure manager add DC.example.com my_reg_key

However, if the device and the FireSIGHT Management Center are separated by a NAT device, enter a unique NAT ID along with the registration key, and specify DONTRESOLVE instead of the hostname, for example: configure manager add DONTRESOLVE my_reg_key my_nat_id

Step 4

Do one of the following:

•

•

(All models.) Use SSH to connect to the ASA FirePOWER management IP address.

(Software modules only.) Open a session to the module from the ASA CLI (see the “Getting Started” chapter in the general operations configuration guide to access the ASA CLI). In multiple context mode, session from the system execution space.

hostname# session sfr

Log in with the username admin or another username that has the CLI configuration (Administrator) access level.

At the prompt, register the device to a FireSIGHT Management Center using the configure manager

add command, which has the following syntax:

configure manager add {hostname | IPv4_address | IPv6_address | DONTRESOLVE} reg_key

[nat_id] where:

•

•

{hostname | IPv4_address | IPv6_address | DONTRESOLVE} specifies either the fully qualified host name or IP address of the FireSIGHT Management Center. If the FireSIGHT Management

Center is not directly addressable, use DONTRESOLVE.

reg_key is the unique alphanumeric registration key required to register a device to the FireSIGHT

Management Center.

• nat_id is an optional alphanumeric string used during the registration process between the

FireSIGHT Management Center and the device. It is required if the hostname is set to

DONTRESOLVE.

Log into the FireSIGHT Management Center using an HTTPS connection in a browser, using the hostname or address entered above. For example, https://DC.example.com.

Use the Device Management (Devices > Device Management) page to add the device. For more information, see the online help or the Managing Devices chapter in the FireSIGHT System User Guide.

Configure the Security Policy on the ASA FirePOWER Module

The security policy controls the services provided by the module, such as Next Generation IPS filtering and application filtering.

You use FireSIGHT Management Center to configure the security policy on the module.

For the ASA 5506-X, you can alternatively use ASDM. However, you can never use both ASDM and

FireSIGHT Management Center, you must choose one or the other. If you configure a FireSIGHT

Management Center for the module, you must use the configured manager. If you do not configure a manager, you must use ASDM.

There is no CLI for configuring the security policy.

Cisco ASA Series Firewall ASDM Configuration Guide

Chapter 16 ASA FirePOWER (SFR) Module

Configure the ASA FirePOWER Module

Configure the Security Policy with FireSIGHT Management Center

To open FireSIGHT Management Center, do one of the following:

• Use a web browser to open https://DC_address, where DC_address is the DNS name or IP address of the manager you defined in

Add ASA FirePOWER to the FireSIGHT Management Center, page 16-16

. For example, https://dc.example.com.

• In ASDM, choose Home > ASA FirePOWER Status and click the link at the bottom of the dashboard.

For information about how to configure the security policy, see the FireSIGHT System User Guide or the online help in FireSIGHT Management Center.

Configure the Security Policy with ASDM

For ASA 5506-X, if you do not configure a FireSIGHT Management Center, you use ASDM to configure the security policy.

ASA FirePOWER pages are separate from the ASA configuration pages. Use the following pages to monitor and configure the module. You can click Help in any page, or choose Help > ASA FirePOWER

Help Topics, to learn more about how to configure policies.

• Home > ASA FirePOWER Dashboard—The dashboard provides summary information about the software running on the module, product updates, licensing, system load, disk usage, system time, and interface status.

•

•

Home > ASA FirePOWER Reporting—The reporting page provides Top 10 dashboards for a wide variety of module statistics, such as web categories, users, sources, and destinations for the traffic passing through the module.

Home > ASA FirePOWER Status—Also available when you manage the module with FireSIGHT

Management Center, the status page includes module information, such as the model, serial number, and software version, and module status, such as the application name and status, data plane status, and overall status. If the module is registered to a FireSIGHT Management Center, you can click the link to open the application and do further analysis and module configuration.

•

•

•

Configuration > ASA FirePOWER Configuration—This drawer includes pages for each ASA

FirePOWER policy, such as access control and intrusion policies. The configuration of these policies is consistent with the same policies in FireSIGHT Management Center, so you can easily transition between the two products. Click Help within the policy page to get detailed information on configuring the policies.

Configuration > Firewall > Access Rules—When you choose to configure ASA FirePOWER with

ASDM, the ASA access rules page includes toggle buttons so that you can easily switch the view between ASA rules and ASA FirePOWER rules. Keep in mind that ASA inbound rules on an interface are always applied before ASA FirePOWER access control policies. Any traffic dropped through inbound rules is never sent to ASA FirePOWER.

Monitoring > ASA FirePOWER Monitoring—There are several pages for monitoring the module, including syslog, task status, module statistics, and a real-time event viewer.

16-18

Cisco ASA Series Firewall ASDM Configuration Guide

Chapter 16 ASA FirePOWER (SFR) Module

Configure the ASA FirePOWER Module

ASDM Restrictions for Managing ASA FirePOWER

Keep the following restrictions in mind when configuring ASA FirePOWER using ASDM.

• If you enable command authorization on the ASA that hosts the module, you must log in with a user name that has privilege level 15 to see the ASA FirePOWER home, configuration, and monitoring pages. Read-only or monitor-only access to ASA FirePOWER pages other than the status page is not supported.

•

•

If you configure the ASA in a failover pair, the ASA FirePOWER configuration is not automatically synchronized with the ASA FirePOWER module on the secondary device. Thus, you must manually export the ASA FirePOWER configuration from the primary and import it into the secondary every time you make a change. We recommend using FireSIGHT Management Center for any device configured for failover.

If you are using Java 7_u51 up to Java 8, you need to import the SSL certificate from the ASA

FirePOWER module to your workstation to view the configuration pages. Go to Wizard > ASDM

Identity Certificate Wizard to obtain the certificate. Then, go to your Java Control Panel and import it, and restart ASDM. This is a general issue with these Java versions, and you will also need to import the certificate from the ASA to configure it through ASDM.

Redirect Traffic to the ASA FirePOWER Module

For inline and inline tap (monitor-only) modes, you configure a service policy to redirect traffic to the module. If you want passive monitor-only mode, you configure a traffic redirection interface, which bypasses ASA policies.

The following topics explain how to configure these modes.

Configure Inline or Inline Tap Monitor-Only Modes

Redirect traffic to the ASA FirePOWER module by creating a service policy that identifies specific traffic that you want to send. In this mode, ASA policies, such as access rules, are applied to the traffic before it is redirected to the module.

Before You Begin

• If you have an active service policy redirecting traffic to an IPS or CX module (that you replaced with the ASA FirePOWER), you must remove that policy before you configure the ASA

FirePOWER service policy.

•

•

Be sure to configure consistent policies on the ASA and the ASA FirePOWER. Both policies should reflect the inline or inline tap mode of the traffic.

In multiple context mode, perform this procedure within each security context.

Procedure

Step 1

Step 2

Step 3

Choose Configuration > Firewall > Service Policy Rules.

Choose Add > Add Service Policy Rule.

Choose whether to apply the policy to a particular interface or apply it globally and click Next.

Configure the ASA FirePOWER Module

Step 4

Step 5

Step 6

Step 7

Step 8

Step 9

Configure the traffic match. For example, you could match Any Traffic so that all traffic that passes your inbound access rules is redirected to the module. Or, you could define stricter criteria based on ports,

ACL (source and destination criteria), or an existing traffic class. The other options are less useful for this policy. After you complete the traffic class definition, click Next.

On the Rule Actions page, click the ASA FirePOWER Inspection tab.

Check the Enable ASA FirePOWER for this traffic flow check box.

In the If ASA FirePOWER Card Fails area, click one of the following:

• Permit traffic—Sets the ASA to allow all traffic through, uninspected, if the module is unavailable.

• Close traffic—Sets the ASA to block all traffic if the module is unavailable.

(Optional) Check Monitor-only to send a read-only copy of traffic to the module, i.e. inline tap mode.

By default, the traffic is sent in inline mode. Be sure to configure consistent policies on the ASA and the

ASA FirePOWER. Both policies should reflect the inline or monitor-only of the traffic.

Click Finish and then Apply.

Repeat this procedure to configure additional traffic flows as desired.

Configure Passive Traffic Forwarding

If you want to operate the module in passive monitor-only mode, where the module gets a copy of the traffic and neither it nor the ASA can affect the network, configure a traffic forwarding interface and connect the interface to a SPAN port on a switch. For more details, see

ASA FirePOWER Passive

Monitor-Only Traffic Forwarding Mode, page 16-4 .

The following guidelines explain the requirements for this deployment mode:

• The ASA must be in single-context and transparent mode.

•

•

•

•

You can configure up to 4 interfaces as traffic-forwarding interfaces. Other ASA interfaces can be used as normal.

Traffic-forwarding interfaces must be physical interfaces, not VLANs or BVIs. The physical interface also cannot have any VLANs associated with it.

Traffic-forwarding interfaces cannot be used for ASA traffic; you cannot name them or configure them for ASA features, including failover or management-only.

You cannot configure both a traffic-forwarding interface and a service policy for ASA FirePOWER traffic.

Procedure

Step 1

Step 2

Enter interface configuration mode for the physical interface you want to use for traffic-forwarding.

interface physical_interface

Example: hostname(config)# interface gigabitethernet 0/5

Remove any name configured for the interface. If this interface was used in any ASA configuration, that configuration is removed. You cannot configure traffic-forwarding on a named interface.

Chapter 16 ASA FirePOWER (SFR) Module

Managing the ASA FirePOWER Module

To reset the module password for the user admin to the default, Sourcefire, use the following command.

Use 1 for a hardware module, sfr for a software module. In multiple context mode, perform this procedure in the system execution space.

session {1 | sfr} do password-reset

For example, session sfr do password-reset.

Reload or Reset the Module

To reload, or to reset and then reload, the module, enter one of the following commands at the ASA CLI.

In multiple context mode, perform this procedure in the system execution space.

• Hardware module (ASA 5585-X): hw-module module 1 {reload | reset}

• Software module (all other models): sw-module module sfr {reload | reset}

Shut Down the Module

Shutting down the module software prepares the module to be safely powered off without losing configuration data. To gracefully shut down the module, enter one of the following commands at the

ASA CLI. In multiple context mode, perform this procedure in the system execution space.

Note If you reload the ASA, the module is not automatically shut down, so we recommend shutting down the module before reloading the ASA.

• Hardware module (ASA 5585-X): hw-module module 1 shutdown

• Software module (all other models): sw-module module sfr shutdown

Uninstall a Software Module Image

You can uninstall a software module image and its associated configuration. In multiple context mode, perform this procedure in the system execution space.

Procedure

Step 1 Uninstall the software module image and associated configuration.

hostname# sw-module module sfr uninstall

Module sfr will be uninstalled. This will completely remove the disk image associated with the sw-module including any configuration that existed within it.

Step 2

Uninstall module sfr? [confirm]

Reload the ASA. You must reload the ASA before you can install a new module.

hostname# reload

Session to the Software Module From the ASA

Use the ASA FirePOWER CLI to configure basic network settings and to troubleshoot the module.

To access the ASA FirePOWER software module CLI from the ASA, you can session from the ASA.

(You cannot session to a hardware module running on a 5585-X.)

You can either session to the module (using Telnet) or create a virtual console session. A console session might be useful if the control plane is down and you cannot establish a Telnet session. In multiple context mode, session from the system execution space.

In either a Telnet or a Console session, you are prompted for a username and password. You can log in with any username configured on the ASA FirePOWER. Initially, the admin username is the only one configured (and it is always available). The initial default password is Sourcefire for the full image, and

Admin123 for the boot image.

• Telnet session: session sfr

•

When in the ASA FirePOWER CLI, to exit back to the ASA CLI, enter any command that would log you out of the module, such as logout or exit, or press Ctrl-Shift-6, x.

Console session: session sfr console

The only way out of a console session is to press Ctrl-Shift-6, x. Logging out of the module leaves you at the module login prompt.

Note Do not use the session sfr console command in conjunction with a terminal server where Ctrl-Shift-6,

x is the escape sequence to return to the terminal server prompt. Ctrl-Shift-6, x is also the sequence to escape the ASA FirePOWER console and return to the ASA prompt. Therefore, if you try to exit the ASA

FirePOWER console in this situation, you instead exit all the way to the terminal server prompt. If you reconnect the terminal server to the ASA, the ASA FirePOWER console session is still active; you can never exit to the ASA prompt. You must use a direct serial connection to return the console to the ASA prompt. Use the session sfr command instead of the console command when facing this situation.

Reimage the 5585-X ASA FirePOWER Hardware Module

If you need to reimage the ASA FirePOWER hardware module in an ASA 5585-X appliance for any reason, you need to install both the Boot Image and a System Software package, in that order. You must install both packages to have a functioning system. Under normal circumstances, you do not need to reimage the system to install upgrade packages.

Cisco ASA Series Firewall ASDM Configuration Guide

16-23

Chapter 16 ASA FirePOWER (SFR) Module

Managing the ASA FirePOWER Module

To install the boot image, you need to TFTP boot the image from the Management-0 port on the ASA

FirePOWER SSP by logging into the module’s Console port. Because the Management-0 port is on an

SSP in the first slot, it is also known as Management1/0, but rommon recognizes it as Management-0 or

Management0/1.

To accomplish a TFTP boot, you must:

• Place the software image on a TFTP server that can be accessed through the Management1/0 interface on the ASA FirePOWER.

•

•

Connect Management1/0 to the network. You must use this interface to TFTP boot the Boot Image.

Configure rommon variables. Press Esc to interrupt the auto-boot process so that you can configure rommon variables.

Once the boot image is installed, you install the System Software package. You must place the package on an HTTP, HTTPS, or FTP server that is accessible from the ASA FirePOWER.

The following procedure explains how to install the boot image and then install the System Software package.

Procedure

Step 1

Step 2

Step 3

Step 4

Step 5

Step 6

Step 7

Step 8

Connect to the Console port. Use the console cable included with the ASA product to connect your PC to the console using a terminal emulator set for 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control. See the hardware guide for your ASA for more information about the console cable.

Enter the system reboot command to reload the system.

When prompted, break out of the boot by pressing Esc. If you see grub start to boot the system, you have waited too long.

This will place you at the rommon prompt.

At the rommon prompt, enter set and configure the following parameters:

• ADDRESS—The management IP address of the module.

•

•

SERVER—The IP address of the TFTP server.

GATEWAY—The gateway address to the TFTP server. If the TFTP server is directly attached to

Management1/0, use the IP address of the TFTP server. If the TFTP server and management address are on the same subnet, do not configure the gateway or TFTP boot will fail.

• IMAGE—The Boot Image path and image name on the TFTP server. For example, if you place the file on the TFTP server in /tftpboot/images/filename.img, the IMAGE value is images/filename.img.

For example:

ADDRESS=10.5.190.199

SERVER=10.5.11.170

GATEWAY=10.5.1.1

IMAGE=asasfr-boot-5.3.1-26-54.img

Enter sync to save the settings.

Enter tftp to initiate the download and boot process.

You will see ! marks to indicate progress. When the boot completes after several minutes, you will see a login prompt.

Log in as admin, with the password Admin123.

Use the setup command to configure the system so that you can install the system software package.

16-24

Cisco ASA Series Firewall ASDM Configuration Guide

Chapter 16 ASA FirePOWER (SFR) Module

Managing the ASA FirePOWER Module

Step 9

You are prompted for the following. Note that the management address and gateway, and DNS information, are the key settings to configure.

•

•

Host name—Up to 65 alphanumeric characters, no spaces. Hyphens are allowed.

Network address—You can set static IPv4 or IPv6 addresses, or use DHCP (for IPv4) or IPv6 stateless autoconfiguration.

• DNS information—You must identify at least one DNS server, and you can also set the domain name and search domain.

NTP information—You can enable NTP and configure the NTP servers, for setting system time.

•

Install the System Software image using the system install command:

system install [noconfirm] url

Include the noconfirm option if you do not want to respond to confirmation messages.

When installation is complete, the system reboots. Allow 10 or more minutes for application component installation and for the ASA FirePOWER services to start.

For example: asasfr-boot> system install http://upgrades.example.com/packages/asasfr-sys-5.3.1-54.pkg

Step 10

Step 11

When the boot completes, log in as admin with the password Sourcefire.

Complete the system configuration as prompted.

You must first read and accept the end user license agreement (EULA). Then change the admin password, then configure the management address and DNS settings, as prompted. You can configure both IPv4 and IPv6 management addresses.

Identify the FireSIGHT Management Center appliance that will manage this device using the configure

manager add command.

You come up with a registration key, which you will then use in FireSIGHT Management Center when you add the device to its inventory. The following example shows the simple case. When there is a NAT

boundary, the command is different; see Add ASA FirePOWER to the FireSIGHT Management Center, page 16-16

.

> configure manager add 10.89.133.202 123456

Manager successfully configured.

Step 12 Log into the FireSIGHT Management Center using an HTTPS connection in a browser, using the hostname or address entered above. For example, https://DC.example.com.

Use the Device Management (Devices > Device Management) page to add the device. For more information, see the Managing Devices chapter in the FireSIGHT System User Guide or the online help in FireSIGHT Management Center.

Upgrade the System Software

Use FireSIGHT Management Center to apply upgrade images to the ASA FirePOWER module. Before applying an upgrade, ensure that the ASA is running the minimum required release for the new version; you might need to upgrade the ASA prior to upgrading the module. For more information about applying upgrades, see the FireSIGHT System User Guide or the online help in FireSIGHT Management Center.

•

•

Home > ASA FirePOWER Reporting—The reporting page provides Top 10 dashboards for a wide variety of module statistics, such as web categories, users, sources, and destinations for the traffic passing through the module.

Monitoring > ASA FirePOWER Monitoring—There are several pages for monitoring the module, including syslog, task status, module statistics, and a real-time event viewer.

Monitoring Module Connections

To show connections through the ASA FirePOWER module, enter one of the following commands:

• show asp table classify domain sfr

•

Shows the NP rules created to send traffic to the ASA FirePOWER module.

show asp drop

•

Shows dropped packets. The drop types are explained below.

show conn

Shows if a connection is being forwarded to a module by displaying the ‘X - inspected by service module’ flag.

The show asp drop command can include the following drop reasons related to the ASA FirePOWER module.

Frame Drops:

• sfr-bad-tlv-received—This occurs when ASA receives a packet from FirePOWER without a Policy

ID TLV. This TLV must be present in non-control packets if it does not have the Standby/Active bit set in the actions field.

• sfr-request—The frame was requested to be dropped by FirePOWER due a policy on FirePOWER whereby FirePOWER would set the actions to Deny Source, Deny Destination, or Deny Pkt. If the frame should not have been dropped, review the policies on the module that are denying the flow.

•

•

•

• sfr-fail-close—The packet is dropped because the card is not up and the policy configured was

‘fail-close’ (rather than ‘fail-open’ which allows packets through even if the card was down). Check card status and attempt to restart services or reboot it.

sfr-fail—The FirePOWER configuration was removed for an existing flow and we are not able to process it through FirePOWER it will be dropped. This should be very unlikely. sfr-malformed-packet—The packet from FirePOWER contains an invalid header. For instance, the header length may not be correct.

Description

The ASA FirePOWER module supplies next-generation firewall services, including Next-Generation IPS (NGIPS),

Application Visibility and Control (AVC), URL filtering, and Advanced Malware Protection (AMP).You can use the module in single or multiple context mode, and in routed or transparent mode.

We introduced the following screens:

Home > ASA FirePOWER Status

Wizards > Startup Wizard > ASA FirePOWER Basic

Configuration

Configuration > Firewall > Service Policy Rules > Add

Service Policy Rule > Rule Actions > ASA FirePOWER

Inspection

You can run the ASA FirePOWER software module on the

ASA 5506-X. You can manage the module using

FireSIGHT Management Center, or you can use ASDM.

We introduced the following screens:

Home > ASA FirePOWER Dashboard, Home > ASA

FirePOWER Reporting, Configuration > ASA FirePOWER

Configuration (including sub-pages), Monitoring > ASA

FirePOWER Monitoring (including sub-pages).

You can now configure a traffic forwarding interface to send traffic to the module instead of using a service policy. In this mode, neither the module nor the ASA affects the traffic.

We fully supported the following command:

traffic-forward sfr monitor-only. You can configure this in CLI only.
