Designing Access Controls

Choose RADIUS Servers

This option balances reducing traffic with easing management.

Example. Choosing your access control architecture is not as daunting as it may seem—as you can see by following the decision process that the PCU network administrators used. For the sake of this example, PCU has established two satellite campuses, which are connected to the main campus in a WAN.

PCU network administrators begin by considering: should the same policies apply at each site? Because the off-campus sites are not truly autonomous locations, they decide to use the same policies for both. Some students attend classes at both the main campus and a satellite campus location.
