Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Input validation structurally stops untrusted path sequences from being used to construct filenames that escape the intended directory.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and path sanitization that prevent this weakness.

ID.RA-01 partial match
prevents

Vulnerability identification processes will discover path traversal flaws during scanning or testing.

PR.PS-01 partial match
prevents

Hardened configuration baselines can enforce directory restrictions that reduce exploitability.

finds

Security testing in development catches path traversal via static/dynamic analysis and penetration testing.

prevents

Secure development lifecycle mandates input validation and path canonicalization that directly prevent directory traversal sequences.

prevents

Application security requirements explicitly call for controls against path traversal and other injection flaws.

prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific coding fix.

prevents

Secure coding standards require neutralizing '../' sequences and canonicalizing paths before file operations.

none

Information access restriction limits which files can be reached, mitigating impact but not the root cause.
