| Auditing of account use and user actions is a critical part of the security architecture. Auditable events must be logged. If the network element becomes unable to write events to the audit log, this is known as an audit processing failure. Audit processing failures include software and hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded.
In order to determine what is happening within the network infrastructure or to resolve and trace an attack, it is imperative to correlate the log data from multiple firewalls to acquire a clear understanding as to what happened or is happening.
Collecting audit log data and presenting that data in a single, consolidated view achieves this objective. However, audit log analysis and review is not a function of the firewall. |
