| Auditing and logging are key components of any security architecture. It is essential for security personnel to know what is being done, what attempted to be done, where it was done, when it was done, and by whom in order to compile an accurate risk assessment. Logging the actions of specific events provides a means to investigate an attack, recognize resource utilization or capacity thresholds, or to simply identify an improperly configured network element. 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 network elements to acquire a clear understanding as to what happened or is happening. Collecting log data and enabling personnel to filter the data based on selection criteria to produce a meaningful view achieves this objective. This requirement is applicable to network device management and is not applicable to the routing function. |
