The Cisco ASA must be configured to produce audit records containing sufficient information to establish what type of event occurred.

An XCCDF Rule

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. Associating an event type with each event log entry provides a means of investigating an attack or identifying an improperly configured IDPS. While auditing and logging are closely related, they are not the same. Logging is recording data about events that take place in a system, while auditing is the use of log records to identify security-relevant information such as system or user accesses. In short, log records are audited to establish an accurate history. Without logging, it would be impossible to establish an audit trail.
