| 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 that the log data from multiple firewalls be correlated to gain a clear understanding of what happened or is happening.
Collecting the audit log data and presenting the data in a single, consolidated view achieves this objective. However, this is not a function of the firewall with regards to the audit log. |
