Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly neutralizes path sequences so the traversal cannot be introduced or exploited.

Enforces access authorizations on the resulting pathname, blocking traversal attempts from succeeding.

Enforces information flow rules that stop unauthorized directory escapes via crafted paths.

Least privilege reduces the impact of any successful traversal by limiting accessible resources.

prevents

Secure SDLC practices directly require input validation and path sanitization that neutralize traversal sequences.

finds

Security testing in development can detect path-traversal flaws before release.

prevents

Secure SDLC mandates input validation and path-handling controls that directly mitigate path traversal.

prevents

Application security requirements include rules for safe file-path construction and canonicalization.

prevents

Secure architecture principles require proper directory restrictions and input sanitization to prevent traversal.

prevents

Secure coding standards explicitly forbid unsafe path concatenation and mandate canonicalization routines.

mitigates

Information access restriction limits file reachability but does not address the input-validation flaw itself.
