Ensure the NGINX service account is locked

MoyenneNiveau 1Automatiséenginx

Description

The NGINX service account must not have a usable password and should be explicitly locked in the system's shadow file to prevent direct login or password-based privilege escalation. Reads the account from the user directive and expects passwd -S to report L or LK (run as root). Evaluated on the merged configuration printed by `nginx -T` (all included files; needs permission to read them). CIS marks this recommendation Manual; the automated check implements its audit procedure.
