CCI-000195

The information system, for password-based authentication, when new passwords are created, enforces that at least an organization-defined number of characters are changed.

Implementation Guidance

The organization being inspected/assessed configures the information system to enforce that at least 50% of the minimum password length is changed. 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 195. DoD has defined the minimum number of characters as 50% of the minimum password length.

Validation Procedures

The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed configures the information system to enforce that at least 50% of the minimum password length is changed. 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 195. DoD has defined the minimum number of characters as 50% of the minimum password length.
