ACL

Access Control Lists

Traditional UNIX-style file permissions allow a file to be owned by a user and a group, then Read Write and Execute permissions to be set for those two groups and also for everyone else. This is a simple compact method of controling file permissions in 8 bytes or less.

Access Control Lists extend this idea by allowing finer granularity and broader scope. Instead of limiting RWX permissions to user, group and other, permissions can be granted or revoked for arbitrary users and groups.
