| 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. All sensors of the IDPS must be configurable with the organizationally defined rules.
This requirement does not require each sensor be configured with separate rule sets; however, this capability must be available to meet the need to respond to future attack vectors. If administrators do not have granular control of the rule to be applied and logged for later analysis, then malicious attacks may be missed. |
