Create an Exclusion

To exclude events or event field values from triggering an analytics rule, create an exclusion.

To create an exclusion, you define two properties: the conditions events or event field values must match for it to be excluded from triggering an analytics rule; and the scope of the rules to which the exclusion applies.

The conditions events or event field values must match for it to be excluded from triggering an analytics rule are defined in an expression using specific syntax.

You can configure up to 1000 exclusions.

  1. Under Rule Exclusions, click Add.

    The Threat Detection Management Analytics Rules tab showing the Add button under Rule Exclusions highlighted in a red rectangle.

    OR

    In Exclusions, click + New Rule.

    The Exclusions window with the + New Rule button highlighted in a red rectangle.

    OR

    For a specific analytics rule, click the More menu The more options menu; three vertical dark grey dots on an off-white background., then select Exclude.

  2. Enter information about the exclusion:

    • Exclusion Name – Enter the exclusion name.

    • (Optional) Description – Enter details about the purpose or use of the exclusion.

    • Condition – Enter an expression that defines the events or event field values excluded from triggering an analytics rule. Ensure that you use the appropriate syntax.

    • Scope – Define the rules to which the exclusion applies:

      • To exclude events or event field values matching the conditions from triggering any rule, select All.

      • To exclude events or event field values matching the conditions from triggering one or more specific rules, select Specific rules. Click the empty field, then from the list, select a rule. To find a specific rule, start typing, then select a rule from the list.

      • To exclude events or event field values matching the conditions from triggering one or more analytics rule families, select Specific rule families. Click the empty field, then from the list, select a family. To find a specific analytics rule family, start typing, then select a family from the list.

  3. Create the exclusion in enabled or disabled status:

    • If you're creating multiple exclusions, it's best to create them in disabled status and enable them all at once.

      When you enable exclusions, the analytics engine restarts and re-trains on past events with the exclusions and temporarily stops processing incoming events. Enabling multiple exclusions at once minimizes disruptions to other Exabeam applications, analytics engine downtime, and your use of entitled training days.

      To create the exclusion in a disabled state, click Create.

    • To create and enable the exclusion, click Create & Enable. The analytics engine restarts and retrains analytics rules, which can take up to 10 minutes.
