AuthShield: NFS Identity Guard

Enterprises lose confidence in NFS AUTH_SYS because low‑port binding lets privileged users spoof identities and access other users' files. AuthShield replaces insecure AUTH_SYS with lightweight, zero‑root token‑based authentication that enforces true user identity across NFS mounts without requiring kernel changes.

Comment on: NFS AUTH_SYS identity spoofing, still the default in NFSv4

Note that the libnfs/LD_PRELOAD demo is an outright lie. By default, nfs3 mounts have "secure" option - it's not really that secure, but it does require privileged client port (<1024). So no, a root-less user can't impersonate a different user to the same machine."Reading another user’s files" won't work, "Writing as another user" won't work, "Local impersonation via SUID binary" won't work either. You need root to bind to low port, and if you have it, there is no need to mess with NFS.It's not to say that NFS is a secure filesystem by modem means - if there are clients where attacker has root
