Mitigating Controls (NIST 800-53 r5) AI

Proper enforcement of access authorizations on the resolved target resource stops a link from reaching an unintended object.

Least-privilege limits the damage an attacker can cause after following an unintended link.

Validating file-name inputs can reject or canonicalize names that resolve to links before access occurs.

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

finds

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.

mitigates

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