NIST SP 800-53 SA-8(32) Sufficient Documentation

Requirements NIST SOURCE

Implement the security design principle of sufficient documentation in [systems or system components].

Discussion (NIST Supplemental Guidance)

The principle of sufficient documentation states that organizational personnel with responsibilities to interact with the system are provided with adequate documentation and other information such that the personnel contribute to rather than detract from system security. Despite attempts to comply with principles such as human factored security and acceptable security, systems are inherently complex, and the design intent for the use of security mechanisms and the ramifications of the misuse or misconfiguration of security mechanisms are not always intuitively obvious. Uninformed and insufficiently trained users can introduce vulnerabilities due to errors of omission and commission. The availability of documentation and training can help to ensure a knowledgeable cadre of personnel, all of whom have a critical role in the achievement of principles such as continuous protection. Documentation is written clearly and supported by training that provides security awareness and understanding of security-relevant responsibilities.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

systems or system components that implement the security design principle of sufficient documentation are defined;
<SA-08(32)_ODP systems or system components> implement the security design principle of sufficient documentation.

Examine

[SELECT FROM: System and services acquisition policy; procedures addressing the security design principle of sufficient documentation used in the specification, design, development, implementation, and modification of the system; system design documentation; system configuration settings and associated documentation; change control records; security and privacy requirements and specifications for the system; system security and privacy documentation; 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 sufficient documentation in system specification, design, development, implementation, and modification; mechanisms supporting the application of the security design principle of sufficient documentation in system specification, design, development, implementation, and modification; mechanisms that enforce security policies; organizational processes for managing change configuration; mechanisms supporting configuration control].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SA-8(32). 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.
