| Description |
| Without establishing what type of event occurred, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. Audit event 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 network element logs provides a means of investigating an attack, recognizing resource usage or capacity thresholds, or identifying an improperly configured network element. Satisfies: SRG-NET-000074-FW-000009, SRG-NET-000061-FW-000001, SRG-NET-000075-FW-000010, SRG-NET-000076-FW-000011, SRG-NET-000077-FW-000012, SRG-NET-000078-FW-000013, SRG-NET-000492-FW-000006, SRG-NET-000493-FW-000007 |
