TOSS audit records must contain information to establish what type of events occurred, when the events occurred, the source of events, where events occurred, and the outcome of events.

Description
Without establishing what type of events occurred, when events occurred, the source of events, where events occurred, and the outcome of events, 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 TOSS audit logs provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured TOSS system.
