SC-18 Mobile code
What the standard requires
a. Define acceptable and unacceptable mobile code and mobile code technologies; and b. Authorize, monitor, and control the use of mobile code within the system.
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 SC-18 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.
