Discussion

Auditing and logging are key components of any security architecture. Logging the actions of specific events provides a means to investigate an attack; to recognize resource utilization or capacity thresholds; or to identify an improperly configured network device. If auditing is not comprehensive, it will not be useful for intrusion monitoring, security investigations, and forensic analysis. If the Data Plane CPU utilization is 100%, this may indicate an attack or simply an over-utilized device. In either case, action must be taken to identify the source of the issue and take corrective action.
