Access-control list
In computer security, an access-control list (ACL) is a list of permissions 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. 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 Resource Access Control Facility (RACF) profile CONSOLE CLASS(TSOAUTH) has an ACL that contains(ALICE:READ), this would give ALICE permission to use the TSO CONSOLE command.
