| 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. For sound configuration management, it is imperative events associated with a non-local administrative access or diagnostic session be logged.
All maintenance sessions to a DNS system should be logged regardless of whether the session is local or non-local. |
