What's new

Splunk Enterprise Security version 6.5.0 includes the following enhancements:

Risk framework enhancements

New Feature or Enhancement Description
Changes to the workbench panels to include additional pie charts and additional fields (User, Source, and Destination), and human readable MITRE tactics and techniques for easier root cause analysis and targeted threat isolation. Use pie charts and other visual graphics on the workbench panels for more effective threat isolation. Use the User, Source, and Destination fields on the workbench panels to perform root cause analysis for more isolated threat isolation and investigation. Use the Workbench panels to identify the distribution of artifacts by human readable MITRE attack techniques and tactics for a clear visual insight insight into the severity of the events occurring in my system or network. For more information on targeted threat investigation using workbench panels, see Classify risk objects for targeted threat investigation.
Enrich risk events with analytic stories For more actionable guidance to detect, analyze and address security threats, risk events are automatically enriched with an analytic stories field if the correlation search is associated with an analytic story.
Changes to the Risk Factors Editor to associate risk objects with threat objects Associate threat object values to risk events in the Risk factors Editor to make threat investigation easier. For more information on adding threat objects to adhoc risk entries, see Create adhoc risk entry. For more information on adding a threat object to modify an adaptive response action, see Add a threat object to modify an adaptive response action.

Threat Intelligence enhancements

New Feature or Enhancement Description
Opt-in and opt-out feature for Google searches Use the opt-in and opt-out feature in Enterprise Security when you use Google searches to avoid the risk of letting third parties from accessing data. For more information on using Google searches, see Use Google searches to investigate threat risk.

Behavior changes

Following is a list of bug fixes and behavior changes:

New Feature or Enhancement Description
Modifying risk factors upon upgrade Upgrading to Enterprise Security 6.4.1 or higher does not allow you to remove existing fields using the Risk Factors Editor but only allows you to add fields to the risk data model. This prevents the mismatch between the default and local configuration of the risk data model. For more information on upgrade issues with the risk data model, see After upgrading from version 6.2.0 or lower to a version 6.3.0 or higher
No support for Malware Domains threatlist The Malware Domains threatlist is not supported in Enterprise security version 6.5.0 or higher.

Cloud security monitoring

Monitor and respond to threats in your cloud environment. The majority of changes for cloud security monitoring are in the Common Information Model Add-on Manual. See Release notes for the Splunk Common Information Model Add-on in the Administer Splunk Enterprise Security manual.

New Feature or Enhancement Description
Support for storage use case Support for Enterprise Security Content Update (ESCU) use case: "Detect S3 access from a new IP - Rule". Use this S3 access logging information from new IPs during security and access audits for greater insight into your environment.
