Definitions for "Access Control Lists"
A structure, attached to a software object, that defines access permissions for multiple users and groups. It extends the security concepts defined by the HP-UX file system mode bits by allowing specification of the access rights of many individuals and groups instead of just one of each.
The group of access directives that you define. The directives grant levels of access to specific data for specific clients, or groups of clients, or both.
Rules for packet filters (typically routers) that define which packets to pass and which to block.
Database that describes the type of access each user has to a service.
Most network security systems operate by allowing selective use of services. An access control list is the usual means by which the system controls access to, and denial of, its services. It matches a list of available services, with the names of the hosts permitted to use those services.
