• Detection and Security Enhancements
• Platform Enhancements
• Enhancements for International Compatibility
• Changed Functionality
• Terminology

For detailed information, see the FireSIGHT System User Guide, FireSIGHT System Installation Guide, FireSIGHT System Virtual Installation Guide, and Cisco NGIPS for Blue Coat X-Series Installation and Configuration Guide.

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.

---

Caution If you plan to use SSL policies, you must update your Version 5.4 managed devices to Version 5.4.0.1 and your Version 5.4 Defense Centers to Version 5.4.1.

---

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.

---

Caution If you had either the latency packet handling or latency rule handling preprocessors disabled in a previously applied access control policy, updating your Defense Center to Version 5.4 automatically enables both preprocessors with high thresholds. To modify either preprocessor settings so they are no longer enabled, upgrade your Defense Center to Version 5.4.1 and disable either the Packet Handling option or the Rule Handling option in the Advanced Tab of the access control policy, then reapply your policies.

---

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 IoOC support from FireAMP Connectors

The list of Indicators of Compromise 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.

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 With the FireSIGHT System, Version 5.4, the supported ESXi versions are upgraded to 5.0, 5.1, and 5.5.

---

Support for vmxet3 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.

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.

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.

Dedicated AMP Appliances

Version 5.4 also introduces two 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 as the AMP8360, AMP8370, and AMP8390, for 2, 3, and 4 stacks, respectively.

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.

Before You Begin: Important Update and Compatibility Notes

Before you begin the update process for Version 5.4, you should familiarize yourself with the behavior of the system during the update process, as well as with any compatibility issues or required pre- or post-update configuration changes.

Note To reduce the time to update to Version 5.4.0, install the Version 5.4.0 Pre-Installation Package before you update. For more information, see FireSIGHT System Release Notes for the Version 5.4.0 Pre-Installation Package.

Caution Cisco strongly recommends you perform the update in a maintenance window or at a time when the interruption will have the least impact on your deployment.

---

For more information, see the following sections:

• Configuration and Event Backup Guidelines
• Traffic Flow and Inspection During the Update
• Audit Logging During the Update
• Version Requirements for Updating to Version 5.4
• Time and Disk Space Requirements for Updating to Version 5.4
• Product Compatibility After Updating to Version 5.4
• Installing the Update

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.

---

Traffic Flow and Inspection During the Update

The update process reboots managed devices. Depending on how your devices are configured and deployed, the following capabilities are affected:

• traffic inspection, including application awareness and 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 devices, the system performs the update one device at a time to avoid traffic interruption.

Traffic Inspection and Link State

In an inline deployment, your managed devices (depending on model) can affect traffic flow via application control, user control, URL filtering, Security Intelligence, and intrusion prevention, as well as switching, routing, NAT, and VPN. For more information on appliance capabilities, see the FireSIGHT System Installation Guide.

The following table provides details on how traffic flow, inspection, and link state are affected during the update, depending on your deployment. Note that regardless of how you configured any inline sets, switching, routing, NAT, and VPN are not performed during the update process.

 

Table 1-2 Network Traffic Interruptions

Deployment	Network Traffic Interrupted?
Inline with configurable bypass ( Configurable bypass option enabled for inline sets)	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 virtual devices, Cisco NGIPS for Blue Coat X-Series, Cisco ASA with FirePOWER Services, non-bypass NetMods on 8000 Series devices, or SFP transceivers on 71xx Family devices.
Inline	Network traffic is blocked throughout the update.
Passive	Network traffic is not interrupted, but also is not inspected during the update.

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.

Time and Disk Space Requirements for Updating to Version 5.4

The table below provides disk space and time guidelines for the Version 5.4 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.

 

Table 1-3 Time and Disk Space Requirements

Appliance	Space on /	Space on /Volume	Space on /Volume on Manager	Time

Web Browser Compatibility

Version 5.4 of the web interface for the FireSIGHT System has been tested on the browsers listed in the following table.

---

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.

---

 

Table 5 Supported Web Browsers

Browser	Required Enabled Options and Settings
Chrome 40	JavaScript, cookies
Firefox 36	JavaScript, cookies, Secure Sockets Layer (SSL) v3
Microsoft Internet Explorer 9, 10, and 11	JavaScript, cookies, Secure Sockets Layer (SSL) v3, 128-bit encryption, Active scripting security setting, Compatibility View, set Check for newer versions of stored pages to Automatically

---

Note 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.

Installing the Update

Before you begin the update, you must thoroughly read and understand these release notes, especially Before You Begin: Important Update and Compatibility Notes.

Note Updates can require large data transfers from the Firepower Management Center to managed devices. Before you begin, make sure your management network has sufficient bandwidth to successfully perform the transfer. See the Troubleshooting Tech Note at https://www.cisco.com/c/en/us/support/docs/security/ firepower-management-center/212043-Guidelines-for-Downloading-Data-from-the.html.

You can update Defense Centers and ASA FirePOWER modules running at least Version 5.3.1 of the FireSIGHT System to Version 5.4. You can update Series 2 devices running at least Version 5.3.1 of the FireSIGHT System to Version 5.4. To update your appliances to Version 5.4, see the guidelines and procedures outlined below:

• Updating Defense Centers
• Updating Managed Devices and ASA FirePOWER Modules

Caution Do not reboot or shut down your appliances during the update until 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.

---

When to Perform the Update

Because the update process may affect traffic inspection, traffic flow, and link state, Cisco strongly recommends you perform the update in a maintenance window or at a time when the interruption will have the least impact on your deployment.

Installation Method

Use the Defense Center’s web interface to perform the update. Update the Defense Center first, then use it to update the devices it manages.

Order of Installation

Update your Defense Centers before updating the devices they manage.

Installing the Update on Paired Defense Centers

When you begin to update one Defense Center in a high availability pair, the other Defense Center in the pair becomes the primary, if it is not already. In addition, the paired Defense Centers stop sharing configuration information; paired Defense Centers do not receive software updates as part of the regular synchronization process.

To ensure continuity of operations, do not update paired Defense Centers at the same time. First, complete the update procedure for the secondary Defense Center, then update the primary Defense Center.

Installing the Update on Clustered Devices

When you install an update on clustered devices, the system performs the update on the devices one at a time. When the update starts, the system first applies it to the secondary device, which goes into maintenance mode until any necessary processes restart and the device is processing traffic again. The system then applies the update to the primary device, which follows the same process.

Installing the Update on Stacked Devices

When you install an update on stacked devices, the system performs the updates simultaneously. Each device resumes normal operation when the update completes. Note that:

• If the primary device completes the update before all of the secondary devices, the stack operates in a limited, mixed-version state until all devices have completed the update.
• If the primary device completes the update after all of the secondary devices, the stack resumes normal operation when the update completes on the primary device.

Installing the Update on Cisco NGIPS for Blue Coat X-Series

You cannot update Cisco NGIPS for Blue Coat X-Series running Version 5.3.0.x of the FireSIGHT System directly to Version 5.4. Instead, you must uninstall the previous version and install Version 5.4. Note that this results in the loss of all configuration and event data on the X-Series installation. For more information, see the Cisco NGIPS for Blue Coat X-Series Installation and Configuration Guide.

After the Installation

After you perform the update on either the Defense Center or managed devices, you must reapply device configuration and access control policies. Applying an access control policy may cause 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.

There are several additional post-update steps you should take to ensure that your deployment is performing properly. These include:

• verifying that the update succeeded
• making sure that all appliances in your deployment are communicating successfully
• updating to the latest patch for Version 5.4, if available, to take advantage of the latest enhancements and security fixes
• optionally, updating your intrusion rules and vulnerability database (VDB) and reapplying your access control policies
• making any required configuration changes based on the information in New Features and Functionality

The next sections include detailed instructions not only on performing the update, but also on completing any post-update steps. Make sure you complete all of the listed tasks.

Updating Defense Centers

---

Note To reduce the time to update to Version 5.4.0, install the Version 5.4.0 Pre-Installation Package before you update. For more information, see FireSIGHT System Release Notes for the Version 5.4.0 Pre-Installation Package.

---

Use the procedure in this section to update your Defense Centers, including virtual Defense Centers. For the Version 5.4 update, Defense Centers reboot.

---

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 removes existing uninstallers from the appliance.

---

---

Note If you have inline normalization enabled and you update a Defense Center currently running Version 5.3.x to Version 5.4, the update process does not change the behavior of your policies. The system now adds user layers as necessary to preserve the settings that carried over.

---

To update a Defense Center:

---

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

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

Step 2 Download the update from the Support site:

• for Series 2 Defense Centers:

Sourcefire_3D_Defense_Center_Upgrade-5.4.0-xxx.sh

• for Series 3 and virtual Defense Centers:

Sourcefire_3D_Defense_Center_S3_Upgrade-5.4.0-xxx.sh

---

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

---

Step 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.

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

Step 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.

Step 6 Select System > Updates.

The Product Updates tab appears.

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

The Install Update page appears.

Step 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.

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

Step 10 Log into the Defense Center.

Step 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.

Step 12 Select Help > About and confirm that the software version is listed correctly: Version 5.4. Also note the versions of the rule update and VDB on the Defense Center; you will need this information later.

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

Step 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.

Step 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.

Step 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.

Step 17 Reapply access control policies to all managed devices.

---

Caution If you disabled either the latency packet handling or latency rule handling preprocessors in an access control policy prior to updating your Defense Center to Version 5.4 and do not want the preprocessors automatically enabled, do not reapply access control policies after updating your Defense Center to Version 5.4. To modify either preprocessor setting so they are no longer enabled, upgrade your Defense Center to Version 5.4.1 and disable either the Packet Handling option or the Rule Handling option in the Advanced Tab of the access control policy, then reapply your policies.

---

---

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

---

Applying an access control policy may cause 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.

Step 18 If a patch for Version 5.4 is available on the Support site, apply the latest patch as described in the FireSIGHT System Release Notes for that version.

---

Caution If you plan to use SSL policies, you must update your Version 5.4 managed devices to Version 5.4.0.1 and your Version 5.4 Defense Centers to Version 5.4.1.

---

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

---

 

Updating Managed Devices and ASA FirePOWER Modules

After you update your Defense Centers to Version 5.4, 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. Because they do not have a web interface, you must use the Defense Center to update your virtual managed devices. ASA FirePOWER modules do not have a web interface you can use to update the ASA FirePOWER modules. To update your physical and virtual ASA FirePOWER modules, use your Defense Center.

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.

For the Version 5.4 update, all devices reboot. 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 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:

---

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

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

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

Step 3 Download the update from the Support site:

• for Series 2 managed devices:

Sourcefire_3D_Device_Upgrade-5.4.0-xxx.sh

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

---

Step 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.

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

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

The Install Update page appears.

Step 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.

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

Step 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.

---

Step 10 Select Devices > Device Management and confirm that the devices you updated have the correct software version: Version 5.4.

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

Step 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.

---

Step 13 Reapply access control policies to all managed devices.

Applying an access control policy may cause 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.

Step 14 If a patch for Version 5.4 is available on the Support site, apply the latest patch as described in the FireSIGHT System Release Notes for that version.

---

Caution If you plan to use SSL policies, you must update your Version 5.4 managed devices to Version 5.4.0.1 and your Version 5.4 Defense Centers to Version 5.4.1.

---

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

Known Issues

The following known issues are reported in Version 5.4:

• In some cases, if a Microsoft Windows update occurs on a client transferring a file, detection of that file fails because the client transmits pieces of the file in separate sessions that the system cannot reassemble to detect the complete file. (112284/CSCze88424)
• You cannot reapply an intrusion policy (individually or as part of an access control policy reapply) a total of 4096 or more times to a single managed device. (134385/CSCze89030)
• Configuring a proxy server to authenticate with Message Digest 5 (MD5) password encryption for malware cloud lookups is not supported. (135279/CSCze89442)
• The system requires additional time to reboot appliances or ASA FirePOWER modules running Version 5.3 or later due to a database check. If errors are found during the database check, the reboot requires additional time to repair the database. (135564, 136439)
• In some cases, if you create an intrusion rule and add a file_type and a file_group to your detection options, moving the file_type detection option up or down in order clears the selection you made for file_group when it should not. (139441/CSCze91218)
• In some cases, if you disable the IPV6 support option on a virtual router and save, the system generates an error and does not save the router configuration. (141718/CSCze93309)
• In some cases, if you view the threat score of some files from generated events, the system may incorrectly report the threat score as a number instead of Low, Medium, High, or Very High. (142290/CSCze93722)
• In some cases, if you create an SSL rule with logging enabled, the connection events page ( Analysis > Connections > Events) does not display the URL category or URL reputation values. (142878/CSCze93434)
• If you create a new report ( Overview > Reporting > Report Templates) and attempt to insert a report parameter while viewing the web interface with Internet Explorer 11, no report parameters are added to the report section description. As a workaround, use Internet Explorer 10. (142950/CSCze94011)
• The FireSIGHT System User Guide does not reflect that if your Defense Center loses connectivity to the Internet, the system may take up to 30 minutes to generate an Advanced Malware Protection health alert. (143070/CSCze94138)
• In some cases, if you create an SSL policy with the Session Not Cached option under the Undecryptable Actions tab set to Do Not Decrypt or Block and SSL session reuse is enabled, when the session is refreshed, the system may display uncached session errors in the SSL Status column of the Connection Events table view. Cisco recommends creating an SSL policy with the Session Not Cached option set to Do Not Decrypt so traffic is not blocked. (143335/CSCze93608)
• If you register a managed device running Version 5.3.x to a Defense Center running Version 5.4, the system does not display data for the Network Analysis Policy column of the Intrusion Events table view and the Connection Events table view. (143349/CSCze94484)
• In some cases, if your clustered Series 3 devices go into maintenance mode, then experience a power failure and you attempt to reboot the devices, the system does not recover. Contact Support if your device does not successfully recover from maintenance mode. (143504/CSCze94928)
• In some cases, if you create an access control rule set to allow traffic that references an SSL rule set to Decrypt-Resign and an intrusion rule set to drop when inline, the system incorrectly displays the SSL Status as Unknown in the intrusion events table view ( Analysis > Intrusion > Events). (143665/CSCze94947)
• In some cases, the system incorrectly displays file names containing colons ( :) on the file events table view page ( Analysis > Files > File Events). (143666/CSCze94954)
• In some cases, if you add users to an ASA managed device running a fresh installation of Version 5.4, the system does not include show users as a supported CLI command. (144400/CSCze95719)
• In some cases, if you create an access control policy referencing a rule with the HTTP response page set with an Interactive Block action and you attempt to access a URL that should generate an HTTP response page, you are unable to access the same web page in additional tabs on the same browser. (144419/CSCze95694)
• If you create a custom network variable that is named identically to a default variable but contains different capitalization, the system incorrectly assumes the custom variable is the default variable and you cannot delete it. (144488/CSCze95591)
• In some cases, if you configure the local configuration of your Defense Center or managed device so eth1 is enabled for DHCP and Event Only Traffic, the system incorrectly saves the configuration with both eth0 and eth1 enabled for DHCP when only eth1 should be configured for DHCP. (144525/CSCze95666)
• In some cases, if you apply an access control policy with archive file types enabled on a device running an older vulnerability database (VDB), policy apply fails. As a workaround, update your device with the latest VDB and reapply the policy. (144533/CSCze95570)
• The Appliance Information dashboard widget does not display the status for all active management interfaces. (144567/CSCze95021)
• In some cases, if you create link aggregation group (LAG) interfaces on a NetMod connected to an 8000 Series managed device and remove the NetMod after powering down the device, the device attempts to load the configured interfaces from the NetMod instead of deleting the interface groups and generates an Unable to load container error. (144576/CSCze95166)
• If you remove the URL Filtering license from your system, the traffic sent to the cloud is disrupted. Do not remove your URL Filtering license from your system. (144578/CSCze95183)
• If you want to configure alerts for retrospective events or network-based malware events, you must configure both a discovery event alert and an Advanced Malware Protection alert. (144657/CSCze95041)
• In some cases, if you create an HTML report and use Mozilla Firefox to open the report, Firefox displays the report data as binary data when it should not. (144667/CSCze95195)
• The system does not stop intrusion rule updates if there are errors during the installation process. Contact Support if you do not see any imported rules in the rule update import log. (145039/CSCze95385)
• In some cases, if you backup and then restore your Defense Center, the system does not restore any locally-created Security Intelligence (SI) objects from the backup even though web interface display and the restored policies reference the SI objects. As a workaround, re-create your SI objects. (CSCur42337)
• In some cases, if the system attempts to download a file but the download is blocked and the file is downloaded again, the system either does not identify the file type or the system generates incorrect SHA-256 values. (CSCus87799)
• In some cases, if you attempt to upgrade a pair of Defense Centers in high availability from a version older than Version 5.4 directly to Version 5.4.1 without syncing the Defense Centers at Version 5.4, the system generates an error and all access control policies are corrupted. As a workaround, upgrade the Defense Centers in high availability to Version 5.4 and sync the pair of Defense Centers before upgrading to Version 5.4.1. (CSCut60825)
