Terminology

The terminology used in Version 5.4.1.7 and Version 5.4.0.8 may differ from the terminology used in previous releases. For more information, see the Firepower Compatibility Guide.

 

Tip: Cisco documentation may refer to the Defense Center as the FireSIGHT Management Center. The Defense Center and the FireSIGHT Management Center are the same appliance.

Changed Functionality

There is no changed functionality in Version 5.4.0.8 or Version 5.4.1.7.

Features and Functionality Introduced in Previous Versions

Version 5.4.1.1

Dedicated AMP Appliances

Version 5.4 introduces a new Series 3 FirePOWER managed devices designed with additional processing power to maximize the performance of the FireSIGHT System’s AMP features. The AMP8050 is a 81xx Family device with support for Netmods and includes the additional storage necessary to function as a dedicated AMP appliance. The AMP8350 is an 83xx Family device also with support for Netmods and the additional storage required for AMP functionality. The AMP8350 model can be used as a stacked unit with the AMP8360, AMP8370, and AMP8390, for 2, 3, and 4 stacks, respectively.

Version 5.4.1:

FirePOWER Services Management Capabilities

Centralized Management of Cisco ASA5506-X with FirePOWER Services

The Defense Center is now able to manage FirePOWER Services (ASA FirePOWER devices) implementations running on ASA5506-X devices in the same way it does on all of the other ASA5500-X devices. This enables the management of multiple ASA5506-X devices running ASA FirePOWER devices from a single Defense Center, as long as the ASA platform is running Version 9.3.2.2 or later and the ASA FirePOWER device is running Version 5.4.1 or later. Administrators will be able to configure intrusion detection and prevention policies, advanced malware protection, application control, user and group control, file control, and URL filtering and then apply those configurations to multiple ASA5506-X devices all at once. In addition, Defense Centers provide critical dashboards, event views, alerting capabilities, and reporting from all of your ASA FirePOWER devices in a single view.

Direct Management of Cisco ASA5506-X with FirePOWER Services

Cisco’s Adaptive Security Device Manager (ASDM) can be used to perform the same ASA FirePOWER management functions listed above, but only on one ASA5506-X device at a time. In addition, you can manage system policies, licensing, and back up and restore directly.

Management Limitations of Cisco ASA with FirePOWER Services

At the current time, the Cisco ASA FirePOWER product consists of two different products tightly integrated with each other: the ASA Firewall and the FirePOWER Next-Generation Intrusion Prevention System (NGIPS). Whereas critical data sharing between the two has been accomplished, a unified management platform is still in development.

For this reason, the Cisco ASA functionality is currently managed through the Cisco Security Manager (CSM) or the Adaptive Security Device Manager (ASDM), and the FirePOWER Services functionality is managed through the Cisco Defense Center. As a result, the Defense Center does not support any of the following capabilities:

■Cisco ASA hardware-based features, including clustering, stacking, switching, routing, virtual private networks (VPN), and network address translation (NAT).

■Configuring ASA interfaces. In addition, when FirePOWER Services are deployed in SPAN port mode, any ASA interfaces that have been configured will not be displayed.

■Shutting down, restarting or otherwise managing ASA processes.

■Creating or restoring backups from ASA devices.

■Writing access control rules to match traffic using VLAN tag conditions.

Note: The ASA platform provides these features, configured using the ASA command line interface (CLI) and ASDM. For more information, see the ASA FirePOWER module documentation.

Platform Enhancements

VMware Tool Support

You can now use VMware Tools with FireSIGHT System virtual appliances. This enhances compatibility with the VMware environment and improves management of virtual devices by enabling soft power down, migration, and other virtual specific capabilities. VMware tools are supported on:

■64-bit Virtual Defense Center

■64-bit Virtual managed device

Note: As of Version 5.4 of the FireSIGHT System, the system supports ESXi version 5.0, 5.1, and 5.5.

Support for VMXNET3 Interfaces in VMware Virtual Appliances

VMXNET3 interface types are now supported on virtual devices. This allows you to use high-speed network interfaces, up to 10Gbits/s.

Multiple Management Interfaces

You can now use multiple management interface ports on Series 3 Defense Centers, FirePOWER (Series 3) managed devices, and virtual Defense Centers. You can set one interface for management traffic and another interface for event traffic. This improves deployment options in some environments.

Series 3 Support

Version 5.4 introduces the 3D7050 as a 70xx Family device with a dual core quad thread processor, 8GB of RAM, and a 80GB hard drive.

LACP Support

FirePOWER (Series 3) devices are now able to take part in Link Aggregation Control Protocol (LACP) (IEEE 802.3ad) negotiation to aggregate multiple links together into one. This allows both link redundancy and bandwidth sharing.

Defense Center 2000 (DC2000)

The DC2000 is a new Defense Center appliance platform that offers double the performance and capacity of the DC1500.

Defense Center 4000 (DC4000)

The DC4000 is a new Defense Center appliance platform that offers double the performance and capacity of the DC3500.

International Compatibility Enhancements

Unicode Support

The system now displays the names of files detected through file detection, malware detection, and FireAMP file events. This allows the display of non-Western characters, including those that are double-byte encoded.

Geolocation and Security Intelligence Data in Correlation Rules

The correlation rules engine has been updated to make connection, geolocation, and Security Intelligence data available. This allows you to generate correlated events or take correlated actions based on these two new constraints. For example, if an Impact 1 intrusion event is detected from a specific country, you can set up an alert to log that information to an external syslog server.

Support for Private FireAMP Cloud

With Version 5.4, you can use a private FireAMP cloud rather than the Cisco public cloud. This requires installation of a private cloud virtual appliance. The private cloud mediates interactions with the public cloud so you can gather collected threat information from the public cloud without exposing information from your network.

The following features and functionality were updated in Version 5.4:

Detection and Security Enhancements

Integrated SSL Decryption

FirePOWER (Series 3) devices can now identify SSL communications and decrypt the traffic before applying attack, application, and malware detection. You can use SSL decryption in any of the supported Series 3 device deployment modes, including inline and passive. SSL policies control characteristics of SSL in use within the enterprise, with SSL rules to exert granular control over encrypted traffic logging and handling.

Simplified Normalization and Preprocessor Configuration

You now configure traffic normalization and preprocessing in the access control policy, rather than the intrusion policy. This simplifies configuration, especially for new users. The sensitive data preprocessor, rule states, alerting, and event thresholds can still be configured at an individual intrusion policy level.

New file_type Keyword in the Snort Rule Language

A new file_type keyword is available in the Snort rules language that enables the specification of a file type for detection. This is a streamlined alternative to the existing flowbits -driven method.

Expanded IoC support from FireAMP Connectors

The list of Indicators of Compromise (IoC) provided by FireAMP is now dynamic and data-driven. As new IoCs become available, they are automatically supported by the Defense Center. This enhances the IoC correlation capability in any deployment where FireAMP is used.

Protected Rule Content

A new capability of the Snort rule language is available for use in high-security environments. You can now create a Snort content match using hashed data. This allows the rule writer to specify what content to search for, but never exposes the content in plain text.

Previously Changed Functionality

The following functionality was introduced in Version 5.4.0.7 and 5.4.1.6:

■SCADA preprocessor now supports processing Common Industrialist Protocol (CIP) traffic. CIP configuration is not enabled by default. For more information, see the Configuring SCADA Preprocessing section of the FireSIGHT System User guide. (CSCux85466, CSCuy08100, CSCuy08741)

The following functionality was introduced in Version 5.4.0.6 and 5.4.1.5:

■If the system detects a URL and cannot categorize the requested URL from prior lookup results, the system attempts a secondary URL lookup method. If the URL cannot be categorized within two seconds using the secondary URL lookup method, the system assigns the URL the Uncategorized category and processes the URL.

■The SMTP preprocessor now generates an alert for multi-line authentication command overflow attempts.

■The system now restricts reassembly of packets once the system reaches the max HTTP server flow depth and decreases latency in traffic processing.

The following functionality was introduced in Version 5.4.0.5 and Version 5.4.1.4:

■VLAN tags are now limited to integers between 0 and 4095.

■The system now supports matching SSL traffic on all port values, including values 32,768 and larger.

If the system detects a URL and cannot categorize the requested URL from prior lookup results, the system attempts a secondary URL lookup method. If the URL can not be categorized within two seconds using the secondary URL lookup method, the system assigns the URL the Uncategorized category and processes the URL.

The following functionality was introduced in Version 5.4.0.3 and Version 5.4.1.2:

■You must apply the same access control policy to all devices that you plan to stack or cluster before you configure the stack or cluster except in cases where an applied configuration requires the Snort process to restart. See the How Snort Restarts Affect Traffic section in the FireSIGHT System User Guide.

■You are now able to choose to inspect traffic during policy apply to prevent network disruption.

■The system no longer reports the discovery event status to the Health Policy page.

■You can now create an access control policy that references either an access control rule network condition set to block all IPv6 addresses with ::/0 or a network rule set to block all IPv4 addresses with 0.0.0.0/0 is now supported.

■The system now reports an event for all CPU reports when CPU usage changes from a high level to a normal state.

The following functionality was introduced in Version 5.4.0.2 and Version 5.4.1.1:

■The system now clears all intrusion policy locks when you upload intrusion rules or install intrusion rule updates.

The following functionality was introduced in Version 5.4.1:

■Registered ASA devices now have configurable advanced options on the Advanced tab of the Device Management page (Devices > Device Management).

■The show users CLI command is now supported on ASA devices.

■You can configure alerts only for retrospective events or network-based malware events from the Advanced Malware Protections Alerts tab on the Alerts page.

The following features and functionality were updated in Version 5.4:

■You can now view VLAN tags for connection events in the event viewer (Analysis > Connections > Events).

■The system now identifies login attempts over the FTP, HTTP, and MDNS protocols.

■You can now select archived connection events separately from discovery events for transmission to the eStreamer client.

■The Discovery Event Health Monitor is no longer available in health policies.

■Expand Packet View, previously available in Version 4.10.x, is now a configurable option in Version 5.4 via the Event View Settings tab (Admin > User Preferences > Event View Settings).

■Importing a custom intrusion rule as an .rtf file now generates an Invalid Rules File 'rtf_rule.rtf': Must be a plain text file that is ASCII or UTF-8 encoded warning.

■You can now generate the following intrusion event performance graphs via the Intrusion Event Graphs page (Overview > Summary > Intrusion Event Graphs):

–ECN Flags Normalized in TCP Traffic/Packet

–ECN Flags Normalized in TCP Traffic/Session

–ICMPv4 Echo Normalizations

–ICMPv6 Echo Normalizations

–IPv4 DF Flag Normalizations

–IPv4 Options Normalizations

–IPv4 Reserved Flag Normalizations

–IPv4 Resize Normalizations

–IPv4 TOS Normalizations

–IPv4 TTL Normalizations

■You can now configure the HTTP Referrer and User Agent fields in the Connection Events table view and the Security Intelligence Events table view when configuring the displayed columns.

■You can now view warnings associated with the individual rules of your access control policy via the Access Control Policy page (Policies > Access Control). In the access control policy editor, view a warning by hovering your pointer over the alert icon next to the rule name and reading the warning in the tooltip text, or by selecting the Show Warnings button at the top of the page to view the warnings associated with all the rules referenced in your access control policy.

■In Version 5.4, inline normalization is automatically enabled when you create a network analysis policy with Inline Mode enabled. In previous versions, you had to manually enable inline normalization in your inline intrusion policies. Note that the update from Version 5.3.x to Version 5.4 does not change your inline normalization settings.

■You can now add access control rule port conditions that specify unassigned protocol numbers not included in the Protocol drop-down list.

■You no longer need a secondary rule to control FTP Data Channel in your access control policy.

■The new Decompress SWF File (LZMA), Decompress SWF File (Deflate), and Decompress PDF File (Default) HTTP Inspect preprocessor options offer enhanced decompression support for PDF and SWF file content.

■The TCP stream preprocessor now has enhanced protocol-awareness for SMTP, POP3, and IMAP.

■The system now provides enhanced detection of information in application traffic, including detection of application data in DNS traffic and detection of users in additional protocols.

■You can now configure LDAP authentication to use Common Access Cards (CACs) to associate the card with a user name so a user can log directly into the system using the card.

■The system now offers enhanced GPRS Tunneling Protocol (GTP) support.

Configuration and Event Backup Guidelines

Before you begin the update, Cisco strongly recommends that you delete or move any backup files that reside on your appliance, then back up current event and configuration data to an external location.

Use the Defense Center to back up event and configuration data for itself and the devices it manages. For more information on the backup and restore feature, see the FireSIGHT System User Guide.

Note: The Defense Center purges locally stored backups from previous updates. To retain archived backups, store the backups externally.

Caution: BIOS Version 2.0.1b must be running on your DC2000 and DC4000 appliances in order to update to version 5.4.1.1 or later. If updating your appliances fails due to an incompatible BIOS version, contact Support.

Prior to updating an ASA FirePOWER module running FirePOWER Services or a Cisco ASA managed by ASDM, set the device clock to the correct time. If an ASA device clock is set to the incorrect time before updating, the Access Control Licensing page does not load.

Traffic Flow and Inspection During the Update

The update process reboots managed devices and might restart the Snort process. Depending on how your devices are configured and deployed, the following capabilities could be affected

■traffic inspection, including application awareness and control, user control, URL filtering, Security Intelligence, intrusion detection and prevention, and connection logging

■traffic flow, including switching, routing, NAT, VPN, and related functionality

■link state

Note that when you update clustered 7000 or 8000 Series devices or device stacks (in 6.0, high availability device or stack pairs), the system performs the update one device at a time to avoid traffic interruption. When you update clustered Cisco ASA with FirePOWER Services, apply the update one device at a time, allowing the update to complete before updating the second device.

The following table explains how Snort restarts affect traffic inspection. It is reasonable to anticipate that the product update could affect traffic similarly.

 

Link State

In 7000 Series and 8000 Series inline deployments with Bypass enabled, network traffic is interrupted at two points during the update:

■At the beginning of the update process, traffic is briefly interrupted while link goes down and up (flaps) and the network card switches into hardware bypass. Traffic is not inspected during hardware bypass.

■After the update finishes, traffic is again briefly interrupted while link flaps, and the network card switches out of bypass. After the endpoints reconnect and reestablish link with the sensor interfaces, traffic is inspected again.

Note: The configurable Bypass option is not supported on NGIPSv devices, Cisco ASA with FirePOWER Services, non-bypass NetMods on 8000 Series devices, or SFP transceivers on 71xx Family devices.

Switching and Routing

Series 3 devices do not perform switching, routing, NAT, VPN, or related functions during the update. If you configured your devices to perform only switching and routing, network traffic is blocked throughout the update.

Audit Logging During the Update

When updating appliances that have a web interface, after the system completes its pre-update tasks and the streamlined update interface page appears, login attempts to the appliance are not reflected in the audit log until the update process is complete and the appliance reboots.

Version Requirements for Updating to Version 5.4.0.8 and Version 5.4.1.7

To update to Version 5.4.1.7, a Defense Center must be running at least Version 5.4. Defense Centers running Version 5.4.1.1 can manage devices running Version 5.4.0.8 and Version 5.4.1.7. If you are running an earlier version, you can obtain updates from the Support site.

Caution: BIOs Version 2.0.1b must be running on DC2000 and DC4000 in order to update to your appliances to Version 5.4.1.1 or later. If updating your appliances fails due to an earlier BIOs version running on your DC2000 or DC4000, contact Support.

Series 2 and Series 3 devices must be running at least Version 5.4.0.5 to update to Version 5.4.0.8.

Cisco ASA with FirePOWER Services (ASA5512-X, ASA5515-X, ASA5525-X, ASA5545-X, ASA5555-X, ASA5585-X-SSP-10, ASA5585-X-SSP-20, ASA5585-X-SSP-40, and the ASA5585-X-SSP-60) must be running at least Version 5.4.0.5 to update to Version 5.4.0.8.

Cisco ASA with FirePOWER Services (ASA5506-X, ASA5506W-X, ASA5506H-X, ASA5508-X, and ASA5516-X) must be running at least Version 5.4.1 to update to Version 5.4.1.7.

The closer your device’s or ASA module’s current version to the release version (Version 5.4.0.8 or Version 5.4.1.7), the less time the update takes.

Time and Disk Space Requirements for Updating to Version 5.4.0.8 and Version 5.4.1.7

The table below provides disk space and time guidelines for the Version 5.4.0.8 and Version 5.4.1.7 update. Note that when you use the Defense Center to update a managed device, the Defense Center requires additional disk space on its /Volume partition.

Caution: Do not restart the update or reboot your appliance at any time during the update process. Cisco provides time estimates as a guide, but actual update times vary depending on the appliance model, deployment, and configuration. Note that the system may appear inactive during the pre-checks portion of the update and after rebooting; this is expected behavior.

The reboot portion of the update includes a database check. If errors are found during the database check, the update requires additional time to complete. System daemons that interact with the database do not run during the database check and repair.

If you encounter issues with the progress of your update, contact Support.

 

Caution: If you update a Defense Center from Version 5.4.0 to Version 5.4.1.7, the system re-installs all intrusion rule updates instead of the latest intrusion rule update and the update takes much longer than the projected time listed in the Time and Disk Space Requirements for Updating to Version 5.4.0.8 and Version 5.4.1.7. To reduce update time, Cisco strongly recommends updating to Version 5.4.1.2, then updating from Version 5.4.1.2 to Version 5.4.1.7.

Product Compatibility After Updating to Version 5.4.0.8 and Version 5.4.1.7

You must use at least Version 5.4.1 of the Defense Center to manage devices running Version 5.4.1.6. To manage an ASA FirePOWER module on an ASA5506-X,ASA5506W-X, ASA5506H-X, ASA5508-X, or ASA5516-X device, you must use at least Version 5.4.1 of the Defense Center.

If you update a Defense Center from Version 5.4.0 to Version 5.4.1.7, the system re-installs all intrusion rule updates instead of the latest intrusion rule update and the update takes much longer than the projected time listed in the Time and Disk Space Requirements for Updating to Version 5.4.0.8 and Version 5.4.1.7. To reduce update time, Cisco strongly recommends updating to Version 5.4.1.2, then updating from Version 5.4.1.2 to Version 5.4.1.7.

 

Caution: If you update a Defense Center from Version 5.4.0 to Version 5.4.1.7, the system re-installs all intrusion rule updates instead of the latest intrusion rule update and the update takes much longer than the projected time listed in the Time and Disk Space Requirements for Updating to Version 5.4.0.8 and Version 5.4.1.7. To reduce update time, Cisco strongly recommends updating to Version 5.4.1.2, then updating from Version 5.4.1.2 to Version 5.4.1.7.

You can install ASA FirePOWER modules running Version 5.4.1.7 in the ISA3000 running Version 9.4(1.225), Version 9.5(2) and later, and Version 9.6(1) and later.

Web Browser Compatibility

Version 5.4.0.8 and Version 5.4.1.7 of the web interface for the FireSIGHT System has been tested on the browsers listed in the following table.

Note: The Chrome browser does not cache static content, such as images, CSS, or Javascript, with the FireSIGHT System-provided self-signed certificate. This may cause FireSIGHT System to redownload static content when you refresh. To avoid this, add a self-signed certificate to the trust store of the browser/OS or use another web browser.

Note: If you use the Microsoft Internet Explorer 11 browser, you must disable the Include local directory path when uploading files to server option in your Internet Explorer settings via Tools > Internet Options > Security > Custom level.

 

Many browsers use Transport Layer Security (TLS) v1.3 by default. If you have an active SSL policy and your browser uses TLSv1.3, websites that support TLSv1.3 fail to load As a workaround, configure your managed device to remove extension 43 (TLS 1.3) from ClientHello negotiation. See this software advisory for more information.

Screen Resolution Compatibility

Cisco recommends selecting a screen resolution that is at least 1280 pixels wide. The user interface is compatible with lower resolutions, but a higher resolution optimizes the display.

Returning to a Previous Version

If you need to return your appliance to a previous release of the FireSIGHT System for any reason, contact Support for more information.

Reimage Appliances

If you need to reimage your appliances to the current release of the FireSIGHT System for any reason, refer to the FireSIGHT System Virtual Installation Guide for virtual appliances, and the Restoring a FireSIGHT System Appliance to Factory Defaults section of the FireSIGHT System Installation Guide for all other appliances.

CAUTION: Reimaging always involves at least one system reboot.

Updating Defense Centers

Use the procedure in this section to update your Defense Centers, including virtual Defense Centers. For the Version 5.4.1.7 update, Defense Centers reboot.

Caution: You must update your DC2000 and DC4000 BIOs to Version 2.0.1b in order to update your appliances to Version 5.4.1.1 or later. Download the BIOs update via the Cisco Support site.

Caution: Before you update the Defense Center, reapply access control policies to any managed devices. Otherwise, the eventual update of the managed device may fail.

Caution: Do not reboot or shut down your appliances during the update until after you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances.

Note: Updating a Defense Center to Version 5.4.1.7 removes existing uninstallers from the appliance.

Caution: If you update a Defense Center from Version 5.4.0 to Version 5.4.1.7, the system re-installs all intrusion rule updates instead of the latest intrusion rule update and the update takes much longer than the projected time listed in the Time and Disk Space Requirements for Updating to Version 5.4.0.8 and Version 5.4.1.7. To reduce update time, Cisco strongly recommends updating to Version 5.4.1.2, then updating from Version 5.4.1.2 to Version 5.4.1.7.

To update a Defense Center:

1. Read these release notes and complete any required pre-update tasks.

For more information, see Before You Begin: Important Update and Compatibility Notes.

2. Download the update from the Support site:

–for Series 3 and virtual Defense Centers:

Note: Download the update directly from the Support site. If you transfer an update file by email, it may become corrupted.

3. Upload the update to the Defense Center by selecting System > Updates, then clicking Upload Update on the Product Updates tab. Browse to the update and click Upload.

The update is uploaded to the Defense Center. The web interface shows the type of update you uploaded, its version number, and the date and time it was generated. The page also indicates whether a reboot is required as part of the update.

4. Make sure that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.

5. View the task queue (System > Monitoring > Task Status) to make sure that there are no tasks in progress.

You must wait until any long-running tasks are complete before you begin the update. Tasks that are running when the update begins are stopped, become failed tasks, and cannot be resumed; you must manually delete them from the task queue after the update completes. The task queue automatically refreshes every 10 seconds.

6. Select System > Updates.

7. Click the install icon next to the update you uploaded.

8. Select the Defense Center and click Install. Confirm that you want to install the update and reboot the Defense Center.

The update process begins. You can begin monitoring the update’s progress in the task queue (System > Monitoring > Task Status). However, after the Defense Center completes its necessary pre-update checks, you are logged out. When you log back in, the Upgrade Status page appears. The Upgrade Status page displays a progress bar and provides details about the script currently running.

If the update fails for any reason, the page displays an error message indicating the time and date of the failure, which script was running when the update failed, and instructions on how to contact Support. Do not restart the update.

Caution: If you encounter any other issue with the update (for example, if a manual refresh of the Update Status page shows no progress for several minutes), do not restart the update. Instead, contact Support.

When the update completes, the Defense Center displays a success message and reboots.

9. After the update finishes, clear your browser cache and force a reload of the browser. Otherwise, the user interface may exhibit unexpected behavior.

10. Log into the Defense Center.

11. Review and accept the End User License Agreement (EULA). Note that you are logged out of the appliance if you do not accept the EULA.

12. Select Help > About and confirm that the software version is listed correctly: Version 5.4.1.7. Also note the versions of the rule update and VDB on the Defense Center; you will need this information later.

13. Verify that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.

14. If the rule update available on the Support site is newer than the rules on your Defense Center, import the newer rules. Do not auto-apply the imported rules at this time.

For information on rule updates, see the FireSIGHT System User Guide.

15. If the VDB available on the Support site is newer than the VDB on your Defense Center, install the latest VDB.

Installing a VDB update causes a short pause in traffic flow and processing, and may also cause a few packets to pass uninspected. For more information, see the FireSIGHT System User Guide.

16. Reapply device configurations to all managed devices.

To reactivate a grayed-out Apply button, edit any interface in the device configuration, then click Save without making changes.

17. Reapply access control policies to all managed devices.

Caution: Do not reapply your intrusion policies individually; you must reapply all access control policies completely.

When you apply an access control policy, resource demands may result in a small number of packets dropping without inspection. Additionally, applying some configurations requires the Snort process to restart, which interrupts traffic inspection. Whether traffic drops during this interruption or passes without further inspection depends on the model of the managed device and how it handles traffic. For more information, see the Configurations that Restart the Snort Process section of the FireSIGHT System User Guide.

After you update your Defense Centers to Version 5.4, Version 5.4.1, or Version 5.4.1.7, use them to update the devices they manage.

A Defense Center must be running at least Version 5.4 to update its managed devices to Version 5.4.1.6. Because they do not have a web interface, you must use the Defense Center to update your virtual managed devices,, and ASA FirePOWER modules.

Updating managed devices is a two-step process. First, download the update from the Support site and upload it to the managing Defense Center. Next, install the software. You can update multiple devices at once, but only if they use the same update file.

When you updated clustered Cisco ASA with FirePOWER Services (in 6.0, high availability device or stack pairs) apply the update one device at a time and allow the update to complete before updating the second device.

Prior to updating an ASA FirePOWER module running FirePOWER Services or a Cisco ASA managed by ASDM, set the device clock to the correct time. If an ASA device clock is set to the incorrect time before updating, the Access Control Licensing page does not load.

For the Version 5.4.0.8 update, all devices reboot; VAP groups reload. Series 3 devices do not perform traffic inspection, switching, routing, NAT, VPN, or related functions during the update. Depending on how your devices are configured and deployed, the update process may also affect traffic flow and link state. For more information, see Traffic Flow and Inspection During the Update.

Caution: Before you update a managed device, use its managing Defense Center to reapply the appropriate access control policy to the managed device. Otherwise, the managed device update may fail.

Caution: Installing the updates and applying policies can interrupt traffic inspection due to Snort restarts and system restarts. How these interruptions affect traffic depends on the model of the managed device and how it handles traffic. For more information, see Traffic Flow and Inspection During the Update.

Caution: Do not reboot or shut down your appliances during the update until after you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances.

To update managed devices and ASA FirePOWER modules, and :

1. Read these release notes and complete any required pre-update tasks.

Note: Download the update directly from the Support site. If you transfer an update file by email, it may become corrupted.

Caution : Failing to set the device clock of an ASA FirePOWER module running FirePOWER Services or a Cisco ASA managed by ASDM to the correct time prior to updating the device causes the Access Control Licensing page to not load.

For more information, see Before You Begin: Important Update and Compatibility Notes.

2. Update the software on the devices’ managing Defense Center; see Updating Defense Centers.

3. Download the update from the Support site:

–for Series 2 managed devices:

–for Series 3 managed devices:

–for virtual managed devices:

–for ASA FirePOWER modules (ASA5512-X, ASA5515-X, ASA5525-X, ASA5545-X, ASA5555-X, ASA5585-X-SSP-10, ASA5585-X-SSP-20, ASA5585-X-SSP-40, and ASA5585-X-SSP-60):

–for ASA FirePOWER modules (ASA5506-X, ASA5506W-X, ASA5506H-X, ASA5508-X, ASA5516-X, and the ISA 3000):

4. Upload the update to the Defense Center by selecting System > Updates, then clicking Upload Update on the Product Updates tab. Browse to the update and click Upload.

The update is uploaded to the Defense Center. The web interface shows the type of update you uploaded, its version number, and the date and time it was generated. The page also indicates whether a reboot is required as part of the update.

5. Make sure that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.

6. Click the install icon next to the update you are installing.

7. Select the devices where you want to install the update.

If you are updating a stacked pair, selecting one member of the pair automatically selects the other. You must update members of a stacked pair together.

8. Click Install. Confirm that you want to install the update and reboot the devices.

9. The update process begins. You can monitor the update's progress in the Defense Center’s task queue (System > Monitoring > Task Status).

Note that managed devices may reboot twice during the update; this is expected behavior.

Caution: If you encounter issues with the update (for example, if the task queue indicates that the update has failed or if a manual refresh of the task queue shows no progress for several minutes), do not restart the update. Instead, contact Support.

10. Select Devices > Device Management and confirm that the devices you updated have the correct software version: Version 5.4.0.8.

11. Verify that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.

12. Reapply device configurations to all managed devices.

Tip: To reactivate a grayed-out Apply button, edit any interface in the device configuration, then click Save without making changes.

13. Reapply access control policies to all managed devices.

Caution: When you apply an access control policy, resource demands may result in a small number of packets dropping without inspection. Additionally, applying some configurations requires the Snort process to restart, which interrupts traffic inspection. Whether traffic drops during the interruption or passes without further inspection depends on the model of the managed device and how it handles traffic.For more information, see the Configurations that Restart the Snort Process section in the FireSIGHT System User Guide.

14. If a patch for Version 5.4.0.8 is available on the Support site, apply the latest patch as described in the FireSIGHT System Release Notes for that version.

You must update to the latest patch to take advantage of the latest enhancements and security fixes.
