CCI-000028

The information system prevents encrypted information from bypassing content-checking mechanisms by employing organization-defined procedures or methods.

Implementation Guidance

The organization being inspected/assessed configures the information system to prevent encrypted information from bypassing content-checking mechanisms by employing procedures or methods defined in AC-4 (4), CCI 2193. 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 28.

Validation Procedures

The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed configures the information system to prevent encrypted information from bypassing content-checking mechanisms by employing procedures or methods defined in AC-4 (4), CCI 2193. 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 28.

Compelling Evidence

1.) Signed and dated documentation that ensures that the system is configured to prevent encrypted information from bypassing content-checking mechanisms, as defined in CCI 2193. 2.) Applicable STIG/SRG checks.
