Access-control list
List of permissions for a system resource / From Wikipedia, the free encyclopedia
In computer security, an access-control list (ACL) is a list of permissions[lower-alpha 1] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources.[1] Each entry in a typical ACL specifies a subject and an operation. For instance,
- If a file object has an ACL that contains (Alice: read,write; Bob: read), this would give Alice permission to read and write the file and give Bob permission only to read it.
- If the RACF profile CONSOLE CLASS(TSOAUTH) has an ACL that contains (ALICE:READ), this would give ALICE permission to use the TSO CONSOLE command.
