ASGARD v2.12 Released

by Jan 24, 2022

The new ASGARD Management Center version 2.12 adds new features and fixes several issues that were introduced with the version 2.11 in December last year.

Better Sigma Rule Management

We’ve added new features and improved the usability of the sigma rule management section, which is relevant for the released LogWatcher agent and beta customers testing our new Aurora agent.

 The most important new features are the false positive and response editor, which allows Aurora customers to configure response actions for a triggering rule. 

The false positive filter enables users to add filters that, instead of changing the  original rule, extend it during deployment. This makes it easy to use updated rules with the same custom filter values that are only relevant in the user’s environment. 

Revised Updates Section

The update section for the scanners and signatures has been revised. Each action has been reworked. Users can now trigger and update manually and check the log of the update process in a separate tab.
