Advantages of Protected Subsystems

Using protected subsystems offers several advantages:

With protected subsystems, you havea mechanism to provide conditional access to data that is not availablewith traditional OpenVMS access controls. Traditionally, you giveusers privileges to bypass protection codes or access control lists(ACLs). In giving these privileges, however, you grant users a wide classof access. (Refer to Assigning Privileges forinformation on the power different privileges carry.) Protected subsystemsavoid extensive privilege use by individual users.

Protected subsystems give you an alternative toinstalling images with privilege. Writing a secure privileged imagerequires skill, and failures can compromise system security.

Protected subsystems give you an alternative tocreating protected shareable images (also called user-written systemservices).

Protected subsystems make system management easierbecause unprivileged users can manage them without much assistancefrom you. See System Management Requirements fordetails on system management requirements.
