The Snyk User Management rule detects changes to users in the Snyk platform, focusing on actions such as user creation, modification, or deletion as recorded in Snyk's audit logs. The rule primarily utilizes two log types: Snyk.GroupAudit and Snyk.OrgAudit. The rule is enabled and has a medium severity due to its importance in user management and associated security implications. Key tests include detecting user removals, revocations of invitations, and additions of users to groups. Failures in detecting unallowed SSO settings or unauthorized user additions will also trigger alerts. Additionally, it focuses on a minimal deduplication period of 60 minutes for events and allows for quick action on repeated log entries. This rule helps organizations maintain security by monitoring unexpected changes in user roles and permissions within the Snyk environment. For further reference, detailed operational guidelines can be found on the Snyk documentation page concerning user management.
