NIST 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.
Assessment objectives (SP 800-53A)
Section titled “Assessment objectives (SP 800-53A)”Objectives and methods for SA-23
Determine if [Selection (one or more): design modification; augmentation; reconfiguration] is employed on [Assignment: organization-defined systems or system components] supporting essential services or functions to increase the trustworthiness in those systems or components.
Examine: System and services acquisition policy; procedures addressing design modification, augmentation, or reconfiguration of systems or system components; documented evidence of design modification, augmentation, or reconfiguration; system security plan; supply chain risk management plan; other relevant documents or records.
Interview: Organizational personnel with system and service acquisition responsibilities; organizational personnel with information security responsibilities; organizational personnel with the responsibility for security architecture; organizational personnel responsible for configuration management.
Test: Organizational processes for the modification of design, augmentation, or reconfiguration of systems or system components; mechanisms supporting and/or implementing design modification, augmentation, or reconfiguration of systems or system components.
