Title

Specialization

Control

Employ [Selection (one or more): design modification; augmentation; reconfiguration] on [Assignment: 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.

Parameters
