Privilege use can be audited. Any time that a process uses a privilege, the use of privilege is recorded in the audit trail in the upriv audit token. When privilege names are part of the record, their textual representation is used. The following audit events record use of privilege:
AUE_SETPPRIV audit event – Generates an audit record when a privilege set is changed. The AUE_SETPPRIV audit event is in the pm class.
AUE_MODALLOCPRIV audit event – Generates an audit record when a privilege is added from outside the kernel. The AUE_MODALLOCPRIV audit event is in the ad class.
AUE_MODDEVPLCY audit event – Generates an audit record when the device policy is changed. The AUE_MODDEVPLCY audit event is in the ad class.
AUE_PFEXEC audit event – Generates an audit record when a call is made to execve() with pfexec() enabled. The AUE_PFEXEC audit event is in the as, ex, ps, and ua audit classes. The names of the privileges are included in the audit record.
The successful use of privileges that are in the basic set is not audited. An attempt to use a basic privilege that has been removed from a user's basic set is audited.
