SA-4(2) Acquisition process | design and implementation information for controls
What the standard requires
Require the developer of the system, system component, or system service to provide design and implementation information for the controls that includes: [security-relevant external system interfaces | high-level design | low-level design | source code or hardware schematics | [design and implementation information] ] at [level of detail].
Quoted verbatim from NIST SP 800-53 Rev 5 (OSCAL catalog), which is in the public domain.
Cross-framework mappings
No cross-framework mapping is seeded for this control. That is stated rather than filled in: a mapping nobody authored is worse than a gap you can see.
Track SA-4(2) with evidence behind it
In CMDash this control is a row with an owner, a status, uploaded evidence kept with its full history, and an export an assessor can read.
