Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces access control policies on file objects so that symlink traversal cannot be used to bypass protections on user data.

prevent

Limits application processes to the minimum set of privileges required, reducing the chance that a symlink can reach protected user data outside the app's sandbox.

prevent

Prevents unauthorized access to information in shared system resources (e.g., file-system objects) that could be reached via malicious symlinks.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require code to validate paths and avoid unsafe link following.

detects

Security testing can detect link-following flaws before release.

prevents

Secure SDLC practices can mandate link-resolution checks and canonicalization before file access.

prevents

Application security requirements can explicitly require safe handling of symbolic links and path traversal.

prevents

Secure architecture principles include input validation and safe file-access design patterns.

prevents

Secure coding standards directly address canonicalization and symlink attacks during implementation.

none

Access-control rules can limit which files are reachable, reducing exposure to malicious links.
