Bias-Free Language

The documentation set for this product strives to use bias-free language.

Cisco Cyber Vision, Release 5.6.x

Cisco Cyber Vision Release 5.6.x expands security monitoring, auditability, usability, asset investigation, vulnerability reporting, and network-segmentation workflows. Cyber Vision Secure Remote Access (SRA) adds new storage, naming, and multi-VRF enhancements.

New software features

Cisco Cyber Vision features

This section provides a brief description of the Cisco Cyber Vision Center features included in Release 5.6.x.

Table 1.             New software features for Cisco Cyber Vision Center and Site Manager, Release 5.6.0

Product Impact

Feature

Description

Greater Control

Network Scanner alert type

Introduces the Network Scanner alert type to detect network reconnaissance and scanning attempts. Administrators can add trusted scanner IP addresses to an allowed list so that their activity does not generate alerts.

Better Visibility

Network Detection

Automatically detects networks from analyzed traffic at regular intervals and on demand. Administrators can review, accept, update, or discard detected networks and manually define networks with custom properties and organizational hierarchies.

Ease of Process

Assets page enhancement

Provides security, network, and inventory views and a consolidated Summary tab for alerts, vulnerabilities, behaviors, services, and communications. Summary cards and dedicated tabs help users move from an asset overview to detailed information.

Software Reliability

Deep Packet Inspection (DPI) improvements

Adds and enhances DPI support for Niagara Fox on Tridium JACE 9000, Sentinel UDP/1947, AutomationDirect DoMore BRX and Click PLCs, S7plus, Sick Cola2 Netscan, and ABB DCS800 MMS. Also improves DHCP-based Windows profiling, EtherNet/IP device identification, memory use, and protocol-decoding reliability.

Ease of Use

Automatic Purge of Components

Automates the removal of components that meet the configured purge criteria, reducing routine cleanup work.

Ease of Use

Asset Behavior

Introduces behavior-focused information for assets to help users understand observed activity and investigate deviations.

Better Visibility

Snort/IDS enhancements

Enhances Intrusion Detection alerts by displaying the MITRE ATT&CK tactics and techniques mapped to the Snort GID:SID pair that generated the alert. The alert preview shows tactics, and the Summary tab shows the GID:SID pair, tactics, and techniques.

Ease of Use

Segmentation

Introduces Cyber Vision Segmentation and replaces functional groups with asset groups for segmentation workflows. Users can define Security Group Tag identities, model and review rules, review recommendations, and simulate rule impact for supported IE 3x00 switches. Release 5.6.0 does not deploy SGT mappings or Security Group ACL configuration to devices.

Ease of Use

Reworked Asset table view presets

Reworks Asset table presets so users can quickly switch among views for inventory, network, security, and other common tasks.

Ease of Use

View alerts per asset

Shows alerts associated with an asset directly from its Asset Summary page.

Greater Control

Assets with unexpected behaviors alert type

Introduces an alert type that monitors selected assets for specified behaviors within a configurable 1-to-30-day time window. Administrators can select initiator, target, or both roles and assign alert severity. Matching activity raises an alert and can generate Syslog lifecycle events.

Ease of Process

Sensor management extension discontinuation

Discontinues the Sensor Management extension. Sensors previously deployed through the extension are automatically converted and can be managed from the Sensors Management page in the new UI.

Better Visibility

Communications page enhancement

Enhances the New UI Communications map with a left-side control panel for filters, display settings, and legend information; in-place group exploration; contextual details; active-view visibility controls; and right-click quick actions.

Greater Control

Pause or resume individual alert rules

Moves pause and resume actions from the alert-type level to individual alert rules. Administrators can pause or resume one or multiple rules without affecting other rules of the same alert type. Pausing a rule stops new alerts but does not change existing alerts.

Better Visibility

Audit logs

Records supported user authentication and configuration actions in the audit log. Authorized users can review and export audit records and configure a retention period from 7 through 365 days. The default retention period is 90 days.

Ease of Use

Display themes

Lets users display the Cyber Vision interface using the Light or Dark theme or the theme configured for their system. Users select the display theme from the user menu.

Ease of Use

SRA preserves device settings in cloud console after agent removal

Check the Preserve device settings in cloud console after agent removal check box to retain device settings posting removing an agent.

Cyber Vision Secure Remote Access (SRA) features

This section provides a brief description of the Cyber Vision Secure Remote Access (SRA) features included in Release 5.6.x.

Table 2.             New software features for Cyber Vision Secure Remote Access (SRA), Release 5.6.0

Product Impact

Feature

Description

Software Reliability

Azure Blob storage support for session recordings

Adds Azure Blob Storage as a storage option for remote-access session recordings.

Ease of Use

Rename the SEA service to Cyber Vision Secure Remote Access - UI updates

Renames Secure Equipment Access (SEA) to Cyber Vision Secure Remote Access (SRA) and applies the related user-interface changes.

Ease of Use

Eliminate need for email for SSO cross-launch from CV Center to Cyber Vision Secure Remote Access (SRA)

Removes the requirement to provide an email address when using single sign-on to cross-launch Cyber Vision Secure Remote Access from Cisco Cyber Vision Center.

Ease of Setup

Multi-VRF support for CLI and SD-WAN (Cyber Vision Secure Remote Access Agent adjustments)

Updates the remote-access agent to support multi-VRF deployments for CLI-based and Cisco Catalyst SD-WAN workflows.

New hardware features

No new hardware features are included in Release 5.6.0.

FIPS release

A FIPS-compliant Cisco Cyber Vision Center package is available for supported deployment options in Release 5.6.0. FIPS 140-3 defines security requirements for cryptographic modules used to protect sensitive information in computer and telecommunication systems.

If you do not require FIPS compliance for your organization, please download the standard release of Cisco Cyber Vision.

FIPS build limitations

●     Sensors running the FIPS build of the sensor application can only be enrolled in Center instances running the FIPS build of CV Center.

●     By design, it is not possible to cross-update or downgrade from a non-FIPS Center to a FIPS Center, or vice versa.

●     IC3000 sensors are not supported, as the IC3000 does not have a FIPS version of the platform firmware; therefore, the resulting deployment cannot be considered FIPS-compliant.

●     The Cyber Vision sensor self-update is not supported. Sensor updates must be performed manually or by using other automation tools, such as Ansible playbooks.

●     The Cyber Vision Docker sensor and Virtual Machine sensor are not supported.

●     The Cyber Vision report management extension is not supported.

●     Cyber Vision products published in public cloud marketplaces, such as AWS Marketplace, are not FIPS-compliant. Cyber Vision is not supported on AWS GovCloud or other non-standard cloud environments.

Changes in behavior

●     Pause and resume controls move from alert types to individual alert rules in Release 5.6.0. When you upgrade from Release 5.5.x, Cyber Vision sets every rule associated with a paused alert type to Paused. Resume individual rules as needed after the upgrade.

●     After upgrading to Cisco Cyber Vision Release 5.6.x, wait a few days before enabling segmentation. This delay allows Cyber Vision to populate the sensor-to-communication link data required for segmentation.

●     Cisco Cyber Vision Release 5.6.x does not support functional groups. Before upgrading, be aware that the upgrade:

    Deletes all alert rules linked to functional groups.

    Deletes the complete alert history generated by those rules.

    Immediately decreases the corresponding alert counters.

    Stops monitoring and syslog emission for those rules.
