Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover buffer-end violations through static analysis, fuzzing, or dynamic bounds checks.

Security engineering principles require bounds checking, safe arithmetic, and language choices that structurally eliminate post-end buffer accesses.

Input validation enforces bounds on lengths and indices before buffer operations, stopping out-of-bounds accesses after the end of the buffer.

Memory protection mechanisms limit the effects of post-end buffer accesses by blocking unauthorized code execution or data corruption.

finds

Security testing in development can detect buffer-overrun defects before release.

prevents

Secure development life cycle includes buffer-handling practices that reduce out-of-bounds accesses.

prevents

Application security requirements can mandate bounds checking and safe memory APIs.

prevents

Secure architecture principles discourage unsafe pointer arithmetic and unbounded buffers.

prevents

Secure coding standards directly forbid writing or reading past buffer ends.
