| Auditing and logging are key components of any security architecture. It is essential that security personnel know what is being done, what was attempted to be done, where it was done, when it was done, and by whom it was done 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 a network element that has been configured improperly. Mechanisms such as a signed hash using asymmetric cryptography must be used to protect the integrity of the audit tools used for audit reduction and reporting. This requirement is applicable to network device management and is not applicable to the routing function. |
