BIOC rule details

Review BIOC rule fields, exceptions, and status for user-defined and global rules.

Manage your behavioral indicator of compromise (BIOC) rules in Threat Management → Detection Rules → BIOC.

If you are assigned a role that enables Investigation → Rules privileges, you can view all user-defined and preconfigured rules for behavioral indicators of compromise (BIOCs).

If you have Cortex Cloud Analytics enabled, you can also view Analytics BIOCs (ABIOCs) on a separate page. To access this page, click Analytics BIOC Rules next to the refresh icon at the top of the page.

Each page displays fields that are relevant to the specific rule type.
