Operating system auditing capability is critical for accurate forensic analysis. Audit record content that may be necessary to satisfy the requirement of this control includes timestamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked.
Without sufficient information establishing what type of audit events occurred, investigation into the severity of events is severely hindered. As defined in RFC 5424 "The Syslog Protocol", event severity levels allow system administrators and IA personnel to more easily identify critical system issues. |
