CCI-000200

The information system prohibits password reuse for the organization-defined number of generations.

Implementation Guidance

The organization being inspected/assessed configures the information system to prohibit reuse for a minimum of 5 generations. 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 200. DoD has defined the number of generations as a minimum of 5.

Validation Procedures

The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed configures the information system to prohibit reuse for a minimum of 5 generations. 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 200. DoD has defined the number of generations as a minimum of 5.
