The network element must reject or delay network traffic generated above configurable traffic volume thresholds, as defined by the organization.

Description
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. This control addresses the response of the audit logging function to audit processing failures. Traffic volume thresholds must be configured for the audit logs so traffic destined for the logs do not overwhelm the central logging server. Preventing audit processing failures for the central audit logging by rejecting or delaying network traffic is not the function of the IDPS, thus this requirement is not applicable.
