Active lists

The active list is a bucket for data that is used by KUMA correlators for analyzing events according to the correlation rules.

For example, for a list of IP addresses with a bad reputation, you can:

  1. Create a correlation rule of the operational type and add these IP addresses to the active list.
  2. Create a correlation rule of the standard type and specify the active list as filtering criteria.
  3. Create a correlator with this rule.

    In this case, KUMA selects all events that contain the IP addresses in the active list and creates a correlation event.

You can fill active lists automatically using correlation rules of the simple type or import a file that contains data for the active list.

You can add, copy, or delete active lists.

Active lists can be used in the following KUMA services and features:

The same active list can be used by different correlators. However, a separate entity of the active list is created for each correlator. Therefore, the contents of the active lists used by different correlators differ even if the active lists have the same names and IDs.

Only data based on correlation rules of the correlator are added to the active list.

You can add, edit, duplicate, delete, and export records in the active correlator sheet.

During the correlation process, when entries are deleted from active lists, service events are generated in the correlators. These events only exist in the correlators, and they are not redirected to other destinations. Correlation rules can be configured to track these events so that they can be used to identify threats. Service event fields for deleting an entry from the active list are described below.
