Adding wireless routers, switches, hubs or other unsanctioned network expansion devices can disrupt network service to classroom, research, residential and administrative venues. In addition, unsanctioned devices expose the University network and its data to virus, worm and denial of service attacks. For these reasons, the Appropriate Use Policy prohibits connection of personal, private or departmental switches, routers, wireless access points or DHCP-serving devices to centrally-managed network segments.
