Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly implements memory protection mechanisms that prevent exploitation of stack-based buffer overflows such as CWE-121.

prevent

Requires validation of all input to system functions, blocking the malformed data that triggers the stack overflow in DD OS.

prevent

Enforces least privilege so that even local accounts cannot easily obtain the high privileges needed to reach the vulnerable code path.

PR.PS-06 mostly match
prevents

Secure-development practices directly prevent introduction of stack buffer overflows.

ID.RA-01 partial match
prevents

Vulnerability scanning can discover stack buffer overflows but does not prevent their introduction.

PR.PS-02 partial match
prevents

Patching eliminates known instances of the weakness after discovery.

detects

Security testing (fuzzing, static analysis) detects stack overflows before release.

prevents

Secure SDLC mandates buffer-safety practices that directly prevent stack overflows.

prevents

Application security requirements can specify buffer-size and input-validation rules.

prevents

Secure architecture principles include memory-safety and least-privilege stack usage.

prevents

Secure coding standards explicitly forbid unsafe buffer handling that causes CWE-121.

none

Change-management gates can enforce security reviews that catch buffer issues.
