Mitigating Controls (NIST 800-53 r5) AI

prevent

Enforces access control decisions on filesystem objects so that even a high-privileged local user cannot traverse outside intended directories via the '.../...//' flaw.

prevent

Requires validation of path-name inputs to reject traversal sequences such as '.../...//', directly blocking exploitation of CWE-35 in the Data Manager.

prevent

Limits the set of privileges granted to local accounts, reducing the impact of a successful traversal by removing unnecessary filesystem rights.

PR.PS-06 mostly match
prevents

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

detects

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.
