Mitigating Controls (NIST 800-53 r5) AI

SI-3 Malicious Code Protection good match

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

CM-7 Least Functionality partial match

Least functionality restricts the file types and automatic processing capabilities the system will accept.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.
