What's new

Splunk Enterprise Security version 7.0.0 includes the following enhancements:

New features or behavior changes

Following is a list of new features and behavior changes:

New Feature or Enhancement Description
Ability to switch between UI modes Splunk Enterprise Security UI allows you to switch between light and dark modes. The Dark mode is enabled by default when you install Splunk Enterprise Security 7.0 on Splunk Cloud Platform version 8.2.2109 or higher. The dark mode option is not yet available for Splunk Enterprise. For more information, see Change the UI theme.
Executive Security Management Metrics dashboards Executives or SOC managers can use the Executive Security dashboards to get a high level insight into security operations and evaluate security trends over time based on key metrics, notables, risks, and other additional metrics so that they can prioritize security operations and monitor the overall health of the SOC. See Executive Summary dashboards.
Automated updates for the Splunk ES Content Update (ESCU) app When new security content is available, the update process is built into Splunk Enterprise Security so that ES admins always have the latest security content from the Splunk Security Research Team. See Update the Analytic Stories.
Python3 and MLTK 5.x upgrade impact MLTK models created by MLTK versions 5.2.2 and lower and packaged with Enterprise Security 7.0 are not compatible with MLTK versions 5.3.0 or higher. Therefore, you need to regenerate the MLTK models and re-run the MLTK searches when upgrading MLTK and Python Scientific App (PSC) to versions 5.3 and 3.0. Regenerating the models might take time to complete. You can regenerate the MLTK models manually or wait for Enterprise Security to start generating the models on the default schedule. The correlation search results may be inaccurate until the models have been regenerated. For more information, see Python 3 and MLTK 5.x upgrade notes.
New Splunk Enterprise Security use cases Use the following use cases that leverage various features of Splunk Enterprise Security to identify threat and reduce alert volume in your security organizations:
Visualizations of your Cloud security environment using new GDI dashboards You must install and configure Splunk Add-on for Amazon Kinesis Firehose and Splunk Add-on for Microsoft Office 365 from Splunkbase to onboard Cloud data sources and explore your Cloud Security environment using Cloud Security dashboards. For more information on installing and configuring the required TA add-ons, see

Prerequisites to use Cloud Security dashboards.
Explore your Cloud Security environment by displaying visualizations of your Amazon Web Services (AWS) and Microsoft 365 environments using the Cloud Security dashboards. You can access the dashboards through the Cloud Security menu and use them for insights into potential security issues such as errors, unusual events, unintended access, and suspicious activity.
