Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer security testing and code review can discover incorrect buffer-size computations before deployment.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles directly require correct buffer-size arithmetic and bounds-checked allocation.

SI-10 Information Input Validation partial match

Input validation can enforce that supplied lengths or counts used in size calculations are within safe bounds.

SI-16 Memory Protection partial match

Memory-protection mechanisms limit the exploitability of an overflow that results from an incorrect size calculation.

SI-2 Flaw Remediation partial match

Flaw-remediation processes that include vulnerability scanning or static analysis will surface buffer-size errors.
