Access Control List (ACL)

Access Control List (ACL) Definition

Access Control List (ACL)

ACLs contain a list of security principals (these are users, groups, system accounts) and specific permissions granted to each.

When a user attempts to access a resource, the system checks the ACL to determine if a user is allowed to have the requested access. If the user is not on the list or has insufficient permissions, access is denied.
