Title

The operating system must produce audit records containing information to establish what type of events occurred. (Cat II impact)

Discussion

Without establishing what type of events occurred, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. Audit record content that may be necessary to satisfy this requirement includes, for example, time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, filenames involved, and access control or flow control rules invoked. Associating event types with detected events in the operating system audit logs provides a means of investigating an attack; recognizing resource utilization or capacity thresholds; or identifying an improperly configured operating system.

Check Content

Verify the operating system produces audit records containing information to establish what type of events occurred. If it does not, this is a finding.

Fix Text

Configure the operating system to produce audit records containing information to establish what type of events occurred.
