Security testing can detect link-following flaws before release.
Access-control policy defines how permissions must be preserved when objects are copied or shared.
Access-rights provisioning and review processes directly address the risk of overly permissive copied objects.
Privileged-access management includes rules for maintaining correct permissions on copied or restored data.
Secure SDLC practices can mandate link-resolution checks and canonicalization before file access.
Application security requirements can explicitly require safe handling of symbolic links and path traversal.
