CCI-000145

Enforce configurable network communications traffic volume thresholds reflecting limits on audit log storage capacity by delaying or rejecting network traffic above those organization-defined thresholds.

Implementation Guidance

The organization being inspected/assessed configures the information system to delay network communications traffic exceeding the thresholds defined in AU-5 (3), CCI 1859. DoD has defined the action to take as delay. For information system components that have applicable STIGs or SRGs, the organization being inspected/assessed must comply with the STIG/SRG guidance that pertains to CCI 145.

Validation Procedures

The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed configures the information system to delay network communications traffic exceeding the thresholds defined in AU-5 (3), CCI 1859. DoD has defined the action to take as delay. For information system components that have applicable STIGs or SRGs, the organization conducting the inspection/assessment evaluates the components to ensure that the organization being inspected/assessed has configured the information system in compliance with the applicable STIGs and SRGs pertaining to CCI 145.
