Features

For features in earlier releases, see Cisco Secure Firewall Management Center New Features by Release and Cisco Secure Firewall Device Manager New Features by Release.

Upgrade Impact

A feature has upgrade impact if upgrading and deploying can cause the system to process traffic or otherwise act differently without any other action on your part. This is especially common with new threat detection and application identification capabilities. A feature can also have upgrade impact if upgrading requires that you take action before or after upgrade to avoid an undesirable outcome; for example, if you must change a configuration.

The feature descriptions here include upgrade impact where appropriate. For a more complete list of features with upgrade impact by version, see Upgrade Impact Features.

Features in Maintenance Releases

Features, enhancements, and critical fixes included in maintenance releases (third-digit) and patches (fourth-digit) can skip future releases, depending on release date, release type (short term vs. long term), and other factors. Minimize upgrade and other impact by going directly to the latest maintenance release in your chosen version. See Choosing your upgrade target.

If you are using the web interface in a language other than English, features introduced in maintenance releases and patches may not be translated until the next major release.

Intrusion Rules and Keywords

Upgrades can import and auto-enable new and updated intrusion rules and preprocessor rules, modified states for existing rules, and modified default intrusion policy settings. If a newer intrusion rule uses keywords that are not supported in your current version, that rule is not imported when you update the SRU/LSP. After you upgrade and those keywords become supported, the new intrusion rules are imported and, depending on your IPS configuration, can become auto-enabled and thus start generating events and affecting traffic flow.

For details on new keywords, see the Snort release notes: https://www.snort.org/downloads.

FlexConfig

Upgrades can add web interface or Smart CLI support for features that previously required FlexConfig. Although you cannot newly assign or create FlexConfig objects using deprecated commands, in most cases existing FlexConfigs continue to work and you can still deploy. However, sometimes, using deprecated commands can cause deployment issues. The upgrade does not convert FlexConfigs. After upgrade, configure the newly supported features in the web interface or Smart CLI. When you are satisfied with the new configuration, delete the deprecated FlexConfigs.

The feature descriptions here include information on deprecated FlexConfigs when appropriate. For a full list of deprecated FlexConfigs, see your configuration guide.

Integrations and Logging

These integrations and logging facilities may have new features associated with threat defense and management center releases:

Device Management

Recovery-config mode for emergency on-device configuration and out-of-band configuration detection on the Firewall Management Center.

7.7.0

7.7.0

If you lose the management connection to your device, you can make select configuration changes directly at the device CLI to:

  • Restore the management connection if you are using a data interface for manager access.

  • Make select policy changes that can't wait until the connection is restored.

After the management connection is restored, the Firewall Management Center will detect the configuration changes on the device. It does not automatically update the device configuration in the Firewall Management Center; you must view the configuration differences, acknowledge that the device configuration is different, and then manually make the same changes in the Firewall Management Center before you deploy.

New/modified screens: Devices > Device Management > Device > Health > Out of Band Status

New/modified diagnostic CLI (system support diagnostic-cli ) command: configure recovery-config

See: Device Settings, Cisco Secure Firewall Threat Defense Command Reference

Interfaces

Sync Device is now Sync Interfaces.

7.7.0

7.7.0

Sync Device was changed to Sync Interfaces to indicate that this function is only for interface changes. This function no longer detects changes made to the manager access interface; see Devices > Device Management > Device > Management > Manager Access Details: Configuration.

Other out-of-band configuration changes performed at the diagnostic CLI in recovery-config mode need to be discovered at Devices > Device Management > Device > Health > Out of Band Status.

New/modified screens: Devices > Device Management > Interfaces

See: Interfaces

High Availability/Scalability

Management center high availability enhancements.

7.7.0

Any

It is now easier to:

  • Determine when the peers last synced.

  • Compare intrusion rule (SRU/LSP) and vulnerability database (VDB) versions on the peers.

  • Resolve a common device registration issue.

    When device registration fails on the standby peer when you establish high availability, it is often due to stale manager data on the device. Previously, you used the device CLI to resolve this issue. You can now use the Firewall Management Center web interface—click Disable Manager, then Add Manager.

New/modified screens: Integrations > Other Integrations > High Availability

See: High Availability

Threat defense high availability supported with redundant manager access data interfaces.

7.7.0

7.7.0

You can now use redundant manager access data interfaces with Firewall Threat Defense high availability.

7.7.0

7.7.0

You can now use policy based routing to handle traffic based on user-defined domains. Create a basic custom application detector with your domain patterns and the NSG (network service group) tag, then use it in an extended ACL in your PBR policy.

See: Policy Based Routing

Access Control: Threat Detection and Application Identification

Easily block traffic based on TLS version and server certificate status.

7.7.0

7.7.0

New options in the decryption policy wizard make it easier to block traffic based on TLS version and server certificate status. Enabling these options adds predefined rules that do this. After the policy is created, you can edit, reorder, or delete the rules.

New/modified screens: Policies > Decryption > Create Decryption Policy > Blocking

See: Decryption Policies, Decryption Rules

Use EVE to easily bypass decryption for low-risk connections to trusted URLs.

7.7.0

7.7.0

A new Client Threat decryption rule condition and a new option in the decryption policy wizard and make it easier to bypass decryption to trusted URLs for low risk (as identified by EVE) connections.

New decryption policies now include predefined rules that do this, using Category (trusted) and Client Threat (low) conditions. The Client Threat condition is new and represents the EVE verdict. For outbound decryption, you enable/disable these rules as part of creating the policy. For inbound decryption, the rules are disabled by default. After the policy is created, you can edit, reorder, or delete the rules.

New/modified screens: Policies > Decryption > Create Decryption Policy > Decryption Exclusions

Version restrictions: You cannot deploy policies with Client Threat rules to older devices.

See: Decryption Policies, Decryption Rules

New EVE exceptions.

7.7.0

7.7.0

You can now bypass EVE (encrypted visibility engine) block verdicts based on source network and on destination dynamic attributes. And, when bypassing based on network, you can now use FQDN network objects. Previously, you could only block based on destination network or EVE process name and could not use FQDNs.

New/modified screens:

  • To add an exception from the access control policy, in the advanced settings, edit and enable Encrypted Visibility Engine, enable Block Traffic Based on EVE Score, and Add Exception Rule.

  • To add an exception from the Unified Events viewer, right-click a connection that was blocked by EVE and select Add EVE Exception.

See: Cisco Secure Firewall Management Center Snort 3 Configuration Guide

EVE dashboard enhancements.

7.7.0

7.7.0

The Summary dashboard (the default home page for the Firewall Management Center) now includes encrypted visibility engine information in its own tab, including widgets for discovered processes, threat confidence, malicious processes, and connections with detected process names.

The widgets for malicious processes and connections with detected process names are new, and show data from Version 7.7+ devices only. The widgets for discovered processes and threat confidence were previously on the Application Statistics dashboard, and show data from all managed devices. Note that you did modify the EVE tab on the Application Statistics dashboard, the upgrade retains your changes but does not add the new widgets. If you did not modify the tab, it is removed.

See: Dashboards

Event Logging and Analysis

SNI information from the ClientHello message in connection events.

7.7.0

7.7.0

Connection events now include the TLS Client SNI field, which shows the SNI (server name indication) information from the ClientHello message. This indicates the hostname a client is trying to connect to.

See: Connection and Security-Related Connection Events

‘Pending Rule Match’ reason in connection events.

7.7.0

Any

A new connection event reason, Pending Rule Match, marks a connection that ended before it matched any access control role.

See: Connection and Security-Related Connection Events

Health Monitoring

Get alerts before service authentication certificates expire.

7.7.0

7.7.0

To help prevent unexpected service disruptions, a new Certificate Monitoring health module alerts you before service authentication certificates expire on the Firewall Management Center and managed devices.

New/modified screens: System (system gear icon) > Health > Policy > Health Modules > Certificate Monitoring

See: Health

Monitor the event database.

7.7.0

Any

The Firewall Management Center uses a MonetDB database for firewall events and event-related data like connection summaries. A new MonetDB Statistics health module collects database statistics that you can also see in the health monitor: database size, active connections, memory use, data requests processed, slow-running requests, and so on.

This module is enabled for new and upgraded Firewall Management Centers. Troubleshooting best practice is to leave it enabled.

New/modified screens: System (system gear icon) > Health > Policy > Health Modules > MonetDB Statistics

See: Health

Upgrade

Upgrade Firewall Threat Defense or chassis without a manual readiness check.

7.7.0

7.7.0

You no longer have to run time-consuming pre-upgrade readiness checks for Firewall Threat Defense or chassis upgrades. Instead, these checks are now regularly run by the system and reported in the health monitor. This allows you to preemptively fix any issues that will block upgrade.

  • The Database module, new for devices, manages monitors database schema and configuration data (EO) integrity.

  • The FXOS Health module, new for devices, monitors the FXOS httpd service on FXOS-based devices.

  • The Disk Status module is now more robust, alerting on disk health issues reported by daily running of smartctl (a Linux utility for monitoring reliability, predicting failures, and performing other self-tests).

Version restrictions: This feature is supported for upgrades from Version 7.7+. Devices running earlier versions still require the in-upgrade readiness check.

See: Cisco Secure Firewall Threat Defense Upgrade Guide for Management Center

Upgrade Firewall Management Center without a manual readiness check.

7.7.0

Any

You no longer have to run time-consuming pre-upgrade readiness checks for Firewall Management Center upgrades. Instead, these checks are now regularly run by the system and reported in the health monitor. This allows you to preemptively fix any issues that will block upgrade.

Version restrictions: This feature is supported for upgrades from Version 7.7+.

See: Cisco Secure Firewall Threat Defense Upgrade Guide for Management Center

Skip post-upgrade deploy for Firewall Management Center.

7.7.0

Any

In many cases, you no longer have to deploy to Snort 3 devices after you upgrade the Firewall Management Center. If deploy is required, affected devices are marked out of date (with a few exceptions).

Reasons for needing to manually deploy include:

  • The upgrade updated the LSP and scheduled LSP updates are off.

  • The upgrade updated the LSP and scheduled LSP updates are on, but automatic redeploy is off. Devices may not be marked out of date in this case. Note that if automatic redeploy is on, the redeploy will take place on schedule and you do not need to do it manually.

  • Specific configurations changed by the upgrade require a deploy.

  • You need to upgrade managed devices immediately. After Firewall Management Center upgrade, you cannot upgrade managed devices until you redeploy, even if they are not marked out of date.

See: Cisco Secure Firewall Threat Defense Upgrade Guide for Management Center

SRU update moved out of Firewall Management Center upgrade.

7.7.0

Any

Upgrade impact. After Firewall Management Center upgrades to Version 7.7+, wait for SRU to install.

Instead of upgrading the SRU as part of the upgrade, the system now updates intrusion rules for Snort 2 devices (the SRU) after the upgrade completes and the Firewall Management Center reboots. Although this makes the upgrade itself faster, you cannot update intrusion rules, add devices, or deploy configuration changes while the SRU is updating. This occurs regardless of whether you are managing any Snort 2 devices.

See: Cisco Secure Firewall Threat Defense Upgrade Guide for Management Center

Administration

Cancel Firewall Threat Defense backups, view detailed backup status.

7.7.0

7.7.0

The Message Center now displays detailed backup status for the Firewall Management Center and its devices. You can also cancel in-progress device backups.

See: Backup/Restore

Restrict Firewall Management Center SAML SSO logins to a subdomain.

7.7.0

Any

In a multidomain deployment, you can now restrict Firewall Management Center SAML SSO logins to a subdomain. This can only be configured at the global domain level.

See: Users

Clear disk space utility.

7.7.0

7.7.0

A new utility allows you to click to safely remove unneeded files such as old backups, content updates, and troubleshooting files. Low disk space can reduce performance, prevent upgrade, and increase the risk of accidentally deleting important files when trying to recover space.

New/modified screens: We added a Clear disk space button to the Disk Usage widget on health dashboards: System (system gear icon) > Health > Monitor.

See: Troubleshooting

New dark theme and theme name changes.

7.7.0

Any

There are now three themes available for the Firewall Management Center:

  • Light is a renamed New theme—the left-hand navigation theme introduced recently.

  • Dark is a new left-hand navigation theme that replaces the Dusk theme. If you were using the Dusk theme, you are switched to the Dark theme.

  • Legacy is a renamed Light theme.

To change themes, click your username in the top right corner of the Firewall Management Center web interface.

See: Users

Performance and Resiliency

Faster failover for high availability Firewall Threat Defense.

7.7.0

7.7.0

With Firewall Threat Defense high availability failover, the new active device generates multicast packets for each MAC address entry and sends them to all bridge group interfaces, which prompts the upstream switches to update their routing tables. This task now runs asynchronously in the data plane, privileging critical failover tasks in the control plane. This makes failover faster, reducing downtime.

See: High Availability

Dynamic flow offload for the Secure Firewall 3100/4200.

7.7.0

7.7.0

Dynamic flow offload is now supported on the Secure Firewall 3100/4200. Previously, it was only supported on the Firepower 4100/9300. This feature is enabled in new and upgraded deployments.

See: Prefiltering

Use a loopback interface on Firewall Threat Defense Virtual for GCP to receive health probes from the GCP load balancer.

7.7.0

7.7.0

You can now use a dedicated loopback interface on Firewall Threat Defense Virtual for GCP to receive health probes from the GCP load balancer in autoscale deployments. This allows the system to handle health probes more efficiently, improving performance.

See: Cisco Secure Firewall Threat Defense Virtual Getting Started Guide

Configure Firewall Threat Defense autorecovery from block depletion using FlexConfig.

7.7.0

7.7.0

To reduce downtime due to service disruption, a new fault manager monitors block depletion and automatically reloads devices when necessary. In high availability deployments, this triggers failover. Fault monitoring is automatically enabled on new and upgraded devices. To disable, use FlexConfig.

New/modified FlexConfig commands:

  • fault-monitor block-depletion recovery-action { none| reload}

    Specifying none turns off automatic reload, but does not turn off fault monitoring. For that, use no fault-monitoring .

  • fault-monitor block-depletion monitor-interval seconds

    You can configure how long (in seconds) before the device reloads.

New/modified Firewall Threat Defense CLI commands: show fault-monitor block-depletion{ status| statistics}

Platform restrictions: Not supported for clustered devices.

See: Troubleshooting

New IP flow statistics.

7.7.0

7.7.0

When collecting IP flow statistics from Firewall Threat Defense under the direction of Cisco TAC, a new all parameter logs additional statistics to the specified file: port, protocol, application, cumulative latency, and inspection time.

New/modified commands: system support flow-ip-profiling start flow-ip-file filename all { enable| disable}

See: Cisco Secure Firewall Threat Defense Command Reference

Cisco RADKit integration.

7.7.0

7.7.0

Cisco RADKit integration allows Cisco TAC engineers to remotely connect with your deployment (including sudo access) for an enhanced troubleshooting experience. You control the appliances and duration of access. This also gives you and Cisco TAC access to diagnostic data and logs.

New/modified screens: Devices > Remote Diagnostics > Enable the RADKit service

See: Troubleshooting

Security and Hardening

Limited user privileges for Threat Defense CLI Basic user.

7.7.0

7.7.0

The scope of the Threat Defense CLI Basic user privilege is now limited to the following commands: dig, ping, traceroute.

See: Cisco Secure Firewall Threat Defense Virtual Getting Started Guide

Firewall and IPS Features

Hardware bypass support for inline sets.

If your device model supports hardware bypass, you can now configure it for inline sets containing supported interfaces.

We added the Bypass option to inline set configuration.

Deprecated: Snort 2.

Upgrade impact. Cannot upgrade Snort 2 devices.

Snort 2 is deprecated. You cannot upgrade a Snort 2 device to Version 7.7.0+. We removed the ability to switch to Snort 2, as well as the show snort counters and show snort preprocessor-memory-usage commands.

Before you upgrade, switch to Snort 3. See the Intrusion Policies chapter in the guide for your current version: Cisco Secure Firewall Device Manager Configuration Guide.

Administrative Features

Custom login page.

You can customize the device manager login page, including adding an image and text to the login page. For example, you can include disclaimers and warnings where the user must agree prior to login. The text is also shown for SSH sessions.

We added the following page: System Settings > Login Page.

Custom streaming telemetry using Google Remote Procedure Calls (gRPC).

You can configure the device to send system health and telemetry data to an external telemetry collector that uses Google Remote Procedure Calls (gRPC) to collect data. You can then use your telemetry collector to monitor the device and integrate with your custom telemetry solution.

Use the API to configure this feature: /devicesettings/default/telemetrystreamingconfig.

Performance

Faster failover for high availability Firewall Threat Defense.

With threat defense high availability failover, the new active device generates multicast packets for each MAC address entry and sends them to all bridge group interfaces, which prompts the upstream switches to update their routing tables. This task now runs asynchronously in the data plane, privileging critical failover tasks in the control plane. This makes failover faster, reducing downtime.

High-bandwidth encrypted application traffic bypasses unnecessary intrusion inspection.

Specific high-bandwidth encrypted application traffic now bypasses unncessary intrusion inspection even if the connection matches an Allow rule. Intrusion rule (LSP) and vulnerability database (VDB) updates can change the applications bypassed but right now they are: AnyConnect, IPsec, iCloud Private Relay, QUIC (including HTTP/3), Secure RTCP.

Version restrictions: Requires Version 7.2.10+ / 7.6.1+ / 7.7.0+.

Configure Firewall Threat Defense autorecovery from block depletion using FlexConfig.

To reduce downtime due to service disruption, a new fault manager monitors block depletion and automatically reloads devices when necessary. In high availability deployments, this triggers failover. Fault monitoring is automatically enabled on new and upgraded devices. To disable, use FlexConfig.

New/modified FlexConfig commands:

  • fault-monitor block-depletion recovery-action { none| reload}

    Specifying none turns off automatic reload, but does not turn off fault monitoring. For that, use no fault-monitoring .

  • fault-monitor block-depletion monitor-interval seconds

New/modified threat defense CLI commands: show fault-monitor block-depletion{ status| statistics}

Upgrade impact. After upgrade, enable for existing servers.

You can now require the Message-Authenticator attribute in all RADIUS responses, ensuring that the threat defense VPN gateway securely verifies every response from the RADIUS server, whether for RA VPN or access to the device itself.

The Require Message-Authenticator for all RADIUS Responses option is enabled by default for new RADIUS servers. We also recommend you enable it for existing servers. Disabling it may expose firewalls to potential attacks.

New CLI commands: message-authenticator-required

Version restrictions: Requires Version 7.0.7+ / 7.2.10+ / 7.6.1+ / 7.7.0+.

Upgrade Impact Features

A feature has upgrade impact if upgrading and deploying can cause the system to process traffic or otherwise act differently without any other action on your part. This is especially common with new threat detection and application identification capabilities. A feature can also have upgrade impact if upgrading requires that you take action before or after upgrade to avoid an undesirable outcome; for example, if you must change a configuration.


Important


Minimize upgrade and other impact by going directly to the latest maintenance release in your chosen version. See Choosing your upgrade target.

Upgrade Guidelines

The following sections contain release-specific upgrade warnings and guidelines. You should also check for features and bugs with upgrade impact. For general information on time/disk space requirements and on system behavior during upgrade—which can include interruptions to traffic flow and inspection—see the appropriate upgrade guide: For Assistance.

Upgrade Guidelines for the Firepower 4100/9300 Chassis

In most cases, we recommend you use the latest build for your FXOS major version.

For release-specific FXOS upgrade warnings and guidelines, as well as features and bugs with upgrade impact, check all release notes between your current and target version: http://www.cisco.com/go/firepower9300-rns.

Upgrade Path

Planning your upgrade path and order is especially important for large deployments, high availability/clustering, multi-hop upgrades, and situations where you need to coordinate chassis, hosting environment, or other upgrades. Those scenarios, as well as information on revert and uninstall, are covered in more detail in the upgrade guide: For Assistance.

Choosing your upgrade target

Go directly to the latest maintenance release to minimize upgrade and other impact.

Features, enhancements, and critical fixes can skip "future" releases that are ahead by version, but not by release date. For example, if you are up-to-date within major Version A, upgrading to dot-zero Version B can deprecate features and fixes.

If you cannot go to the latest release, at least make sure your current version was released on a date before your target version. In the following table, confirm your current version is listed next to your target version. If it is not, choose a later target.

Upgrading from a patched deployment

Critical fixes in patches (fourth-digit) releases can also skip future releases. If you depend on these critical fixes, verify that your target version contains them. For a full list of release dates, see Cisco Secure Firewall Management Center New Features by Release or Cisco Secure Firewall Device Manager New Features by Release.

Supported upgrades and downgrades

This section summarizes upgrade and downgrade capability. For help with:

Supported upgrades

This table shows the supported direct upgrades for Firewall Management Center and Firewall Threat Defense software.


Note


You can upgrade directly to any major (first and second-digit) or maintenance (third digit) release. Patches change the fourth digit only. You cannot upgrade directly to a patch from a previous major or maintenance release. Although a patched device (fourth-digit) can be managed with an unpatched Firewall Management Center, fully patched deployments undergo enhanced testing.


For the Firepower 4100/9300, the table also lists companion FXOS versions. If a chassis upgrade is required, Firewall Threat Defense upgrade is blocked. In most cases we recommend the latest build in each version; for minimum builds see the Cisco Secure Firewall Threat Defense Compatibility Guide.

It removes significant features, enhancements, and critical fixes included in earlier versions. Upgrade to a later release.

Supported downgrades

If an upgrade or patch succeeds but the system does not function to your expectations, you may be able to revert (Firewall Threat Defense upgrades) or uninstall (Firewall Threat Defense and Firewall Management Center patches). For general information, particularly on common scenarios where returning to a previous version is not supported or recommended, see the upgrade guide: https://cisco.com/go/ftd-upgrade.

Bugs

For bugs in earlier releases, see the release notes for those versions. For cloud deployments, see the Cisco Cloud-delivered Firewall Management Center Release Notes.

For Assistance

Upgrade Guides

In Firewall Management Center deployments, the Firewall Management Center must run the same or newer maintenance (third-digit) release as its managed devices. Upgrade the Firewall Management Center first, then devices. Use the upgrade guide for the version you are currently running—not your target version.

Install Guides

If you cannot or do not want to upgrade, you can freshly install major and maintenance releases. This is also called reimaging. You cannot reimage to a patch. Install the appropriate major or maintenance release, then apply the patch. If you are reimaging to an earlier Firewall Threat Defense version on an FXOS device, perform a full reimage—even for devices where the operating system and software are bundled.
