Repeatable and Documented Procedures
LOW MODERATE HIGHRequirements NIST SOURCE
Implement the security design principle of repeatable and documented procedures in [systems or system components].
Discussion (NIST Supplemental Guidance)
The principle of repeatable and documented procedures states that the techniques and methods employed to construct a system component permit the same component to be completely and correctly reconstructed at a later time. Repeatable and documented procedures support the development of a component that is identical to the component created earlier, which may be in widespread use. In the case of other system artifacts (e.g., documentation and testing results), repeatability supports consistency and the ability to inspect the artifacts. Repeatable and documented procedures can be introduced at various stages within the system development life cycle and contribute to the ability to evaluate assurance claims for the system. Examples include systematic procedures for code development and review, procedures for the configuration management of development tools and system artifacts, and procedures for system delivery.

Assessment
Assessment Objectives
- systems or system components that implement the security design principle of repeatable and documented procedures are defined;
- <SA-08(29)_ODP systems or system components> implement the security design principle of repeatable and documented procedures.
Examine
[SELECT FROM: System and services acquisition policy; procedures addressing the security design principle of repeatable and documented procedures used in the specification, design, development, implementation, and modification of the system; system design documentation; security and privacy requirements and specifications for the system; system security and privacy architecture; system security plan; other relevant documents or records].
Interview
[SELECT FROM: Organizational personnel with the responsibility for determining system security and privacy requirements; organizational personnel with system specification, design, development, implementation, and modification responsibilities; system developers; organizational personnel with information security responsibilities].
Test
[SELECT FROM: Organizational processes for applying the security design principle of repeatable and documented procedures in system specification, design, development, implementation, and modification; mechanisms supporting the application of the security design principle of repeatable and documented procedures in system specification, design, development, implementation, and modification; mechanisms that enforce security policies].

STIGs & CCIs
No STIG checks or CCI mappings are currently loaded for SA-8(29). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
