The AUDIT privilege allows software to append audit records to the system security audit log file using one of four system services: $AUDIT_EVENT, $CHECK_PRIVILEGE, $CHKPRO, or $CHECK_ACCESS. In addition, the $AUDIT_EVENT system service allows all components of an audit message to be specified. As a result, this privilege permits the logging of events that appear to have come from the operating system or a user process. Grant this privilege only to trusted images that need to append audit messages to the system audit log file. Users possessing this privilege can provoke a system failure by attempting to log invalid events with the NSA$M_INTERNAL flag set.
