Release Notes for Splunk Enterprise Security

This version of Splunk Enterprise Security is compatible only with specific versions of the Splunk platform. See Splunk Enterprise system requirements in the Installation and Upgrade Manual.

Because the navigation now respects your local changes, you might need to make changes to the navigation menu bar after upgrading. See Configure > General > Navigation to see which views are upgraded, new, or deprecated.

What's New

Splunk Enterprise Security version 5.2.0 includes the following enhancements.

New Feature or Enhancement	Description
Event Sequencing (new)	Expands threat detection by allowing you to group correlation searches into batches of events. The events can be grouped in a specific sequence, by specific attributes, or both. See Create sequence templates in Splunk Enterprise Security.
Use Case Library (new)	Automatically discover new security use cases and determine which can be used within your environment, based on the data currently being ingested. Splunk Enterprise Security Content Update (ESCU) delivers security analysis guides called analytic stories directly to the Use Case Library. See Map data to use cases.
Adaptive Response Relay (new)	The adaptive response actions that ship out of the box for ping, nbtstat, and nslookup are modified to support Splunk Cloud. Additional setup is required before configuring adaptive response actions from Splunk Cloud to on-premises infrastructure and services. See Set up an adaptive response relay from Splunk Cloud to an on-premises device.
Investigation Workbench (improvement)	Additional artifact types of File and URL are available. You can get notifications about incoming notable events. Token summary view and preview mode are available in the workbench panel editor. The investigation notes window is revised. See Add artifacts to the scope of your investigation.
Content Management (improvement)	Contains a new event information column that can be expanded to verify dependency and usage information. See Expand Content Management searches to view dependency and usage information in Splunk Enterprise Security.
Threat Intelligence (improvement)	Generic intelligence sources available from third parties to enrich your data, such as Cisco Umbrella 1 Million Sites. See Included generic intelligence sources.

Deprecated features

The notable_adhoc_invocations macro in the SA-ThreatIntelligence app is deprecated in favor of the incident review saved search to fix ad-hoc alerts on sequenced events. This macro will be removed in a future release.

The automatic (continuous) creation and deployment of the “indexer package” (Splunk_TA_ForIndexers) to the Indexer tier via deployment server proxy feature is deprecated. See Deploy add-ons to indexers.

Alexa Top 1 Million Sites is deprecated. See Included generic intelligence sources for alternatives.

Add-ons

Technology-specific add-ons are supported differently than the add-ons that make up the Splunk Enterprise Security framework. See Support for Splunk Enterprise Security and provided add-ons in the Release Notes manual.

Add-on deprecation

The automatic inclusion of add-ons listed in Technology-specific add-ons provided with Enterprise Security is deprecated. In a future release, Splunk Enterprise Security will no longer include all of these add-ons in the Splunk Enterprise Security package. Instead, you can download the add-ons that you need directly from Splunkbase. This change improves the performance of Splunk ES by reducing the number of unnecessary enabled add-ons, and allows you to install the most appropriate and updated versions of add-ons when you install Splunk ES.

Also in a future release, Splunk Enterprise Security will no longer selectively import apps and add-ons based on the name of the app or add-on. After this change, knowledge objects in apps and add-ons installed on the same search head as Splunk Enterprise Security and exported to other apps or globally will be visible in Splunk Enterprise Security.

Updated add-ons

The Common Information Model Add-on is updated to version 4.12.0.
