Mitigating Controls (NIST 800-53 r5) AI

Enforces approved authorizations for logical access to stored information, directly stopping unauthorized read/write.

Requires protection of confidentiality/integrity for information at rest, directly addressing insecure storage.

Limits privileges so only authorized accesses to sensitive stored data are permitted.

Developer testing and evaluation directly finds out-of-bounds read flaws through static analysis, fuzzing, and dynamic bounds checks.

Associates security attributes with information to support proper access decisions on storage.

Secure engineering principles require bounds checking and memory-safe constructs that stop out-of-bounds reads from being introduced.

finds

Security testing in development and acceptance includes fuzzing and static analysis that detect out-of-bounds read defects before release.

A.8.15 Logging partial match
finds

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

prevents

Secure development life cycle mandates input validation and bounds checking that directly prevent out-of-bounds reads.

prevents

Application security requirements include explicit bounds and memory-safety specifications that mitigate buffer over-reads.

prevents

Secure system architecture and engineering principles require memory-safe design patterns and runtime protections against out-of-bounds access.

prevents

Secure coding standards explicitly forbid unsafe pointer arithmetic and mandate bounds-checked reads, eliminating CWE-125.
