Setuid e setgid

Sign in to save

In Unix-like systems, the access rights flags setuid and setgid (short for set user identity and set group identity) allow users to run an executable with the file system permissions of the executable's owner or group respectively and to change behaviour in directories. They are often used to allow users on a computer system to run programs with temporarily elevated privileges to perform a specific task. While the assumed user id or group id privileges provided are not always elevated, at a minimum they are specific.

Nei sistemi operativi Unix e Unix-like, setuid (abbreviazione di set user id, assegna l'identificativo utente) e setgid (abbreviazione di set group id, assegna l'identificativo di gruppo) sono dei permessi speciali attribuibili a file e directory che modificano il comportamento del sistema nei loro confronti. Essi possono essere impostati o rimossi tramite il comando chmod.
