Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Input validation directly neutralizes path traversal sequences such as '/../' in externally supplied filenames before they are used to construct paths.
Access enforcement ensures that even a traversed path cannot grant unauthorized access to resources outside the intended directory.
Information flow enforcement can block unauthorized data flows that would result from a successful path traversal.

Secure SDLC practices directly require input validation and path sanitization that prevent traversal flaws.

Secure coding standards require canonicalization and neutralization of '../' sequences in path construction.
Security testing in development catches path-traversal flaws before production deployment.
Secure development lifecycle mandates input validation and path sanitization that directly prevents traversal sequences.
Application security requirements explicitly call for controls against path traversal and directory escape attacks.
Secure architecture principles reduce exposure to path traversal through least-privilege file-system design.
Information access restriction limits which directories users or processes may traverse.
