Ensure no files or directories without an owner and a group exist

中级别 1自动化aix

说明

Administrators may delete users or groups from the system and neglect to remove all files and/or directories owned by those users or groups. A new user or group who is assigned a deleted user's user ID or group ID may then end up "owning" a deleted user or group's files, and thus have more access on the system than was intended. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
