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.
Current versions of Splunk Enterprise Security only support TAXII version 1.0 and TAXII version 1.1.
Splunk Enterprise Security version 7.1.0 includes the following new features or enhancements:
|Ability to enable behavioral analytics service from Splunk Enterprise Security app UI||Option to enable specific detections in Splunk behavioral analytics service to enhance and extend threat hunting in your existing Splunk SIEM environment. |
For more information on enabling the behavioral analytics service, see
|Visualizations for the behavioral analytics service||Use the Risk Analysis dashboard in Splunk Enterprise Security to view the distribution of Behavioral Analytics Detections by Type. For more information, see Risk Analysis dashboard.|
|Use test index to reduce alert volume||Option to manage Splunk behavioral analytics detections by forwarding notables to a test index without impacting the risk environment. For more information on using test index for behavioral analytics service detections, see Manage behavioral analytics service detections in Splunk Enterprise Security.|
|Upgraded dashboards to Splunk Dashboard Framework||Use Splunk Enterprise Security dashboards that are upgraded from simple XML to Splunk Dashboard Framework for improved performance and to get better insights from your data visualizations. Additionally, you can also upgrade your custom dashboards to the Splunk Dashboard Framework.
For more information on using upgraded dashboards, see Upgrade to Splunk Dashboard Studio to improve performance.
|Guidance on risk-based alerting in a new standalone manual||See Use Splunk Enterprise Security Risk-based Alerting to learn about how risk-based alerting works in Splunk Enterprise Security.|
|View risk notables from the same risk object (asset or identity)||Use Splunk Enterprise Security to surface risk notables that are generated from the same risk object but might represent a higher risk so that connected behaviors and threats can be investigated. For more information, see View risk notables generated from the same risk object.|
|View the MITRE ATT&CK posture for a risk notable||View the MITRE ATT&CK tactics and techniques in the context of a risk notable to enhance the situational awareness of your security operations center (SOC). For more information, see View the MITRE ATT&CK posture for a risk notable.|
|View risk notables with enrichment from entity zones||Use Splunk Enterprise Security to surface risk notables based on the additional enrichment provided by entity zones to investigate threats effectively. For more information, see View risk notables with enrichment from entity zones.|
|Visualizations to map risk notables against known security frameworks such as MITRE ATT&CK||Mapping risk notables to known security frameworks through visualizations helps to classify attacks, understand adversary behavior, and assess an organization's risk. For more information on investigating a risk notable based on known security frameworks, see Investigate a risk notable based on known security frameworks.|
|Visualization to map Threat Topology||Use the Threat Topology visualization to identify how the different risk objects that generate a risk notable are related to each other. For more information on using the Threat Topology visualization to identify risk during an investigation, see Use the Threat Topology visualization to analyze risk notables.|
|Visualizations and charts to review notables||Use the pie charts on the Incident Review page for greater insight into the notables and isolate specific time periods of interest during an investigation. For more information on the available visualizations, see Visualizations and charts in Incident Review.|
|Improve performance by troubleshooting large KV Store collections||Troubleshoot search head crashes or slow downs when you exceed storage limits for KV Store collections. For more information, see Troubleshoot performance issues due to large KV Store collections.|
|Wider panels for configuration||Commonly used configuration panels in Splunk Enterprise Security such as the correlation search editor are now wider to provide an easier workflow and to optimize screen real-estate. A wider correlation search editor makes it easy to view and customize Splunk security detections.|
|New telemetry information||Additional usage data is collected by Splunk Enterprise Security to improve the product in future releases. For more information on what new data is collected, see Share data in Splunk Enterprise Security.|
When you upgrade to Splunk Enterprise Security version 7.1.0, contributing risk events for risk notables might not be visible in the Risk Event Timeline if the risk notables are created before the upgrade and any one of the following conditions are met:
- CIM entity zones are enabled
- Changes are made to the CIM entity zones that apply to existing risk notables
- Asset and identity framework is disabled
For more information, see After upgrading to Splunk Enterprise Security Version 7.1.0.
Additionally, if you make changes to the CIM entity zones or the assets and identity framework, you might cause a change to the risk object normalization, which might result in contributing risk events not being visible in the Risk Event Timeline visualization. This pertains to risk notables that were created prior to making the changes to the CIM entity zones and assets and identity framework.
