The macOS system must be configured to audit all authorization and authentication events.
An XCCDF Rule
Description
The auditing system must be configured to flag authorization and authentication (aa) events. Authentication events contain information about the identity of a user, server, or client. Authorization events contain information about permissions, rights, and rules. If audit records do not include aa events, it is difficult to identify incidents and correlate incidents to subsequent events. Audit records can be generated from various components within the information system (e.g., via a module or policy filter).
