Control: Employ [ Selection (one or more): design modification, augmentation, reconfiguration ] on [ Assignment: organization-defined systems or system components ] supporting mission essential services or functions to increase the trustworthiness in those systems or components.

Discussion: It is often necessary for a system or system component that supports mission- essential services or functions to be enhanced to maximize the trustworthiness of the resource. Sometimes this enhancement is done at the design level. In other instances, it is done post- design, either through modifications of the system in question or by augmenting the system with additional components. For example, supplemental authentication or non-repudiation functions may be added to the system to enhance the identity of critical resources to other resources that depend on the organization-defined resources.

Related Controls: RA-9 , SA-8.

Control Enhancements: None.
