New Features and Functionality
This section of the release notes summarizes the new and updated features and functionality included in Version 5.4.1 of the FireSIGHT System:
■FirePOWER Services Management Capabilities
■International Compatibility Enhancements
■Features and Functionality Introduced in Previous Versions
For detailed information, see the FireSIGHT System User Guide, FireSIGHT System Installation Guide, FireSIGHT System Virtual Installation Guide, and Installation and Configuration Guide.
FirePOWER Services Management Capabilities
Centralized Management of Cisco ASA5506-X, ASA5506H-W, ASA5506W-X, ASA5508-X, and ASA5516-X with FirePOWER Services
The Defense Center is now able to manage FirePOWER Services (ASA FirePOWER devices) implementations running on FirePOWER devices in the same way it does on all of the other ASA5500-X devices. This enables the management of multiple FirePOWER devices running ASA FirePOWER devices from a single Defense Center, as long as the ASA platform is running Version 9.3.1 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 FirePOWER 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, ASA5506H-W, ASA5506W-X, ASA5508-X, and ASA5516-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 FirePOWER 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.
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
Note: As of Version 5.4 of the FireSIGHT System, the system supports ESXi version 5.0, version 5.1, and version 5.5.
Multiple Management Interfaces
You can now use multiple management interface ports on Series 3 Defense Centers 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.
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
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.
If you reference documentation for Version 5.3.1.x or Version 5.3.0.x, you may notice the terminology differs from the documentation for Version 5.4.1.

Features and Functionality Introduced in Previous Versions
Features Introduced 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 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
–IPv6 TTL Normalizations
–IPv6 Options Normalizations
–TCP Header Padding Normalizations
–TCP No Option Normalizations
–TCP NS Flag Normalizations
–TCP Options Normalizations
–TCP Packets Blocked by Normalization
–TCP Reserved Flags Normalizations
–TCP Segment Reassembly Normalizations
–TCP SYN Option Normalizations
–Total TCP Filtered Packets
–TCP Timestamp ECR Normalizations
–Total UDP Filtered Packets
–TCP Urgent Flag 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.
You can download all updated documentation from the Support site. In Version 5.4.1, the following documents were updated to reflect the addition of new features and changed functionality and to address reported documentation issues:
■ FireSIGHT System Online Help
■ FireSIGHT System Online Help (SEU)
■ FireSIGHT System User Guide
■ FireSIGHT System Installation Guide
■ FireSIGHT System Virtual Installation Guide
■ FireSIGHT System eStreamer Integration Guide
The documentation updated for Version 5.4.1 contains the following errors:
■The FireSIGHT System User Guide does not reflect that, on devices with limited memory, the number of intrusion policies may not be paired with more than one variable set. In the case where you can apply an access control policy that references only one intrusion policy, verify every reference to the intrusion policy is paired with the same variable set. Pairing an intrusion policy with different variable sets results in more memory usage.
Before You Begin: Important Update and Compatibility Notes
Before you begin the update process for Version 5.4.1, 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.
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
■Audit Logging During the Update
■Version Requirements for Updating to Version 5.4.1
■.Time and Disk Space Requirements for Updating to Version 5.4.1
■Product Compatibility After Updating to Version 5.4.1
■Returning to a Previous Version
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.
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 5.4.1
To update to Version 5.4.1, a Defense Center must be running at least Version 5.4. If you are running an earlier version, you can obtain updates from the Support site.
.Time and Disk Space Requirements for Updating to Version 5.4.1
The table below provides disk space and time guidelines for the Version 5.4.1 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 4 Supported Web Browsers
Required Enabled Options and Settings
Microsoft Internet Explorer 9, 10, and 11
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.
If you need to reimage your appliances to the current release of the FireSIGHT System for any reason, refer to the 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.

Note: To install the ASA FirePOWER module Version 5.4.1 image on the ASA5506-X, see the Cisco ASA FirePOWER Module Quick Start Guide for more information on deploying and installing the module
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.
To update Defense Centers running at least Version 5.4 to Version 5.4.1, see the guidelines and procedures outlined below:
■Updating Defense Centers
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.
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.
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
Use the procedure in this section to update your Defense Centers, including virtual Defense Centers. For the Version 5.4.1 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 5.4.1 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:
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.
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. 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.
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.
18. If a patch for Version 5.4.1 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.
You can track defects resolved in this release using the Cisco Bug Search Tool ( https://tools.cisco.com/bugsearch/). A Cisco account is required. To view defects addressed in older versions, refer to the legacy caveat tracking system.

The following known issues are reported in Version 5.4.1:
■In some cases, your access control policies may appear as out-of-date even when they are not. (14412/CSCze95029)
■In some cases, if you attempt to use the SFR system restart CLI command while logged in via the ASA session command, the device may stop processes and not restart them. This affects all devices except the ASA5506-X. (143135/CSCze94403)
■In some cases, if you create an access control rule set with an interactive block action and enable beginning-of-connection logging or both beginning-of-connection and end-of-connection logging, the system does not log beginning-of-connection events with the reason User Bypass. (143357/CSCze93672, 144167/CSCze94675)
■In some cases, if you apply an access control policy referencing two intrusion policies to two devices, then edit the first intrusion policy, then reapply the policy to one device and cluster the two devices, the modified intrusion policy is marked out-of-date on the second device. As a workaround, apply a different access control policy with the same intrusion policies to the second device. (144136/CSCze95126)
■If you edit a local rule on the Intrusion Rule Editor page ( Policies > Intrusion > Rule Editor), the system displays the current local rule configuration for already-generated event data when viewing rule documentation instead of the rule configuration that triggered them. (145118/CSCze95346)
■In some cases, the system may not display policy-related information for the following columns on the Connection Events table view ( Analysis > Connections > Events): Action, Reason, Access Control Policy, Access Control Rule, and Network Analysis Policy. (145142/CSCze95299)
■In some cases, the system does not display any events in the Total Events, Total Events Last Hour, or Total Events Last Day rows of the statistics summary of the Discovery Statistics page (Overview > Summary > Discovery Statistics). (145153/CSCze95751)
■In some cases, if you generate an intrusion event performance graph (Overview > Summary > Intrusion Event Performance) and select Last Hour as the time range, the generated graph is blank instead of including data from the intrusion events table view. (145237/CSCze95774)
■Your device may experience a prolonged wait period when powering on. (145248/CSCze96068)
■In some cases, if you enable a fail-open Cisco Redundancy Protocol (SFRP) set to monitor-only on a ASA 5515 module in a high availability configuration and your device experiences a failover, your module may change from active to standby mode several times when it should not. (145256/CSCze95812)
■If you configure an ASA FirePOWER module running Version 5.0 or later with network address translation (NAT), the system incorrectly processes data channels matching applied access control, intrusion, and network discovery policies. (145274/CSCze96017)
■If you enable remote storage and create a scheduled email alert response on your Defense Center, the scheduled email alert may disable remote storage and remote storage backups may fail. As a workaround, create local backups and manually place the backups into remote storage. (145288/CSCze95993)
■In some cases, access control rules containing web application conditions may not match against web application traffic if users on your network enter a URL that is not lower case into the address bar. (CSCur37364)
■Under certain conditions, you cannot get URL category or reputation information. (CSCur38971, CSCus59492)
■In some cases, if you backup and then restore your Defense Center, the system does not restore locally-created Security Intelligence objects from the backup even though the web interface and the restored policies reference the Security Intelligence objects. As a workaround, recreate your Security Intelligence objects. (CSCur42337, CSCur35624)
■In some cases, if you make changes on the Advanced Malware Protection Alerts tab of the Alerts page ( Policies > Actions > Alerts) on a system configured with high availability, the changes may not be synchronized properly between the appliances. (CSCur46711)
■In some cases, if you create an intrusion rule set to block multiprotocol label switching (MPLS) traffic and specify either a source IP address or a destination IP address, the system does not block matching traffic. (CSCur46880)
■If you do not deactivate a traffic profile before deleting it, the system allows the deleted profile to continuously use resources without generating traffic. (CSCur48345)
■In some cases, if you configure your cluster of routed Series 3 managed devices with Cisco Redundancy Protocol (SFRP) and apply a network address translation (NAT) rule, both the primary and secondary device of the cluster respond to the address resolution protocol (ARP) detected in matching traffic when only the primary device should respond. As a workaround, designate the SFRP interface on the primary device as the master interface and the SFRP on the secondary device as the backup interface when creating a NAT rule for your clustered devices. (CSCur55568)
■In some cases, if your Defense Center has a file list with SHA-256 file entries and you add a Defense Center in high availability configuration, the secondary Defense Center deletes the existing file list data. (CSCur57708)
■If you create a scheduled task to install a new version of the vulnerability database (VDB) on your Defense Center, the system will not alert you if you already have a recent VDB version installed and the Defense Center switches from active to standby mode every time the task is scheduled. Cisco does not recommend scheduling automatic VDB updates. (CSCur59252)
■If you use an invalid IP address when configuring the DNS preprocessor in an intrusion policy on an 81xx Family device, system functionality may slow down exponentially. To resolve this issue, enter a valid IP address and reapply the intrusion policy. (CSCur59598)
■In some cases, if you configure an inline pair of interfaces including eth1 and eth2 on a virtual device and issue the show traffic-statistics CLI command, the system will only display traffic statistics for eth1 and not for eth2. (CSCur59771)
■In some cases, the Device tab of the Device Management page ( Devices > Device Management) displays yes for licenses that may have expired or been removed from the registered device when it should display no. (CSCur61884)
■In some cases, if you delete a protection license from the licenses page ( System > Licenses), the system does not decrement the number of used licenses when it should. As a workaround, disable the license from the Device Management page ( Devices > Device Management). (CSCur61927)
■If you configure inline sets on a Series 3 managed device with hardware bypass enabled and reboot the device, you may lose interface connectivity for up to 25 seconds. (CSCur64678)
■You cannot apply an existing intrusion policy that is not referenced in the currently-applied access control policy. (CSCur72904)
■An intrusion detected on the ASA5506-X device may not generate alerts for gzip compressed HTTP traffic or chunked HTTP response data where the decompressed or non-chunked data would match. (CSCur77397)
■If you create an intrusion policy referencing a network analysis policy that is set to Ignore Audio/Video Data Channel, the system generates alerts for session initiation protocol (SIP) audio data when it should not. (CSCur83184)
■If you manually configure the time of the Defense Center or managed device into the past, the Health Monitor page ( Health > Health Monitor) does not display alerts. (CSCur85894)
■In some cases, if you attempt to expand the view of a vulnerability of a host with a client application on the vulnerabilities network map ( Analysis > Hosts > Network Map > Vulnerabilities), the system does not include the host or any associated hosts in the leaf nodes. (CSCur86191)
■In some cases, if you configure the router interface of your clustered Series 3 managed devices to both a private IP address and a Cisco Redundancy Protocol (SFRP) IP address, the system does not recognize which IP address is the primary address and does not establish an Open Shortest Path First (OSPF) connection. (CSCur86355)
■In some cases, if you create a network analysis policy with the HTTP preprocessor enabled and Unlimited Decompression enabled, and an intrusion rule set to alert for data within gzip compressed HTTP traffic, the system may not generate alerts for traffic matching the applied intrusion rule beyond 65535 bytes of decompressed data. (CSCur87659)
■In some cases, if you deploy a large database and attempt to create a troubleshoot file on your Defense Center, the system utilizes extraneous memory for the task and generates an Out of memory! error. (CSCur97450)
■You may experience some latency during Snort restart. (CSCus13247)
■You may encounter false positives on the detection of the Sametime application. (CSCus17165)
■You cannot reset the password for the admin user on the ASA5585-X device. (CSCus17991)
■If you configure remote storage of reports using Windows File Sharing (SMB), the $User, Host Report: $Host, Attack Report: $Attack SID, and Sourcefire FireSIGHT Report: $Customer Name templates fail to generate reports in the SMB due to unsupported characters in the report names. (CSCus21871)
■In some cases, indications of compromise (IOC) cannot be removed or resolved from the IOC table view ( Analysis > Hosts > Indications of Compromise) if the host associated with the event has been retired. (CSCus24116)
■Some HTTPS traffic classifications may result in false positives. (CSCus32474)
■In some cases, if you create an SSL policy set to Do Not Decrypt and attempt to establish a session, the system may erroneously report the session was blocked because of a decryption error even though it was not. (CSCus41127)
■In some cases, if you have a single trusted certificate authority (CA) group or object referenced in your applied SSL policy, the system does not allow you to remove the group or object from the policy. As a workaround, add a different CA group or object to the policy and remove the trusted CA group or object from the current SSL policy. (CSCus42239)
■If your ASA5506-X device running Version 5.4.1 does not have a URL license installed or if the license is unavailable, the Cloud Services page ( System > Local > Configuration) erroneously displays a Last URL filtering update message with a timestamp. (CSCus51935)
■In some cases, if you create an URL individual object and add the individual object to an URL group object, then modify the group object, the tooltip for the individual object does not reflect the updated value of the group object. (CSCus51943)
■In some cases, if your URL license is unavailable or deleted and you attempt to add a new URL license, the Enable Automatic Updates option on the Cloud Services page ( System > Local > Configuration) is not checked by default when it should. (CSCus53842)
■In some cases, if you install the new intrusion rule update and then restore a backup to your device, the system erroneously generates an Intrusion Policy is out-of-date message whether the intrusion policy existed before or after the rule update. (CSCus59479)
■In some cases, if your access control policy includes a source and destination address that contains ::/0, the connection events table view ( Analysis > Connections > Events) contains events generated from IPv4 and IPv6 traffic when only IPV6 traffic should be allowed. (CSCus63549)
■In some cases, if you create a file policy with a Block Malware rule positioned after a rule with a Web Application category condition, the system does not block files identified as malware. As a workaround, position the Block Malware rule before the rule with the Web Application category condition. (CSCus64526)
■In some cases, if you apply an access control policy to an ASA5506-X device from a Defense Center, and the policy is associated with multiple intrusion policies where many rules are enabled, policy apply fails. As a workaround, use fewer policies. Each unique combination of an intrusion policy and variable set counts as a policy, and the network access policy associated with the access control policy counts as a policy. (CSCus95519)
The following known issues were reported in previous releases:
■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)
■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 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)
■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, 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 generates an HTTP response page, you are unable to access the same web page in additional tabs on the same browser. (144419/CSCze95694)
■In some cases, if you attempt 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 SHA256 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)
