Find Un-owned Files and Directories

MediaNivel 1Automatizadasolaris

Descripción

Sometimes when administrators delete users from the password file they neglect to remove all files owned by those users from the system. A new user who is assigned the deleted user's user ID or group ID may then end up "owning" these files, and thus have more access on the system than was intended. Audit: long running; false positives may appear under /zones in the global zone.
