CCI-002754

The information system behaves in a predictable and documented manner that reflects organizational and system objectives when invalid inputs are received.

Implementation Guidance

The organization being inspected/assessed documents proper behavior that reflects organizational and system objectives for when invalid inputs are received. The organization being inspected/assessed configures the information system to behave in the documented manner when invalid inputs are received. 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 2754.

Validation Procedures

The organization conducting the inspection/assessment obtains and examines the documented behavior to ensure the organization being inspected/assessed documents proper behavior that reflects organizational and system objectives for when invalid inputs are received. The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed configures the information system to behave in the documented manner when invalid inputs are received. 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 2754.

Compelling Evidence

1.) Signed and dated System security plan documents proper behavior that reflects organizational and system objectives for when invalid inputs are received. 2.) Configuration documentation that the information system behaves in the documented manner when invalid inputs are received. 3.) Applicable STIG/SRG checks pertaining to CCI 2754.
