Contrary to popular belief, CNS does not actively monitor users for torrenting activity; however, they are obligated to forward DMCA notifications to the relevant parties. Residential users that engage in peer-to-peer filesharing are often throttled (according to policy) if their daily upload average exceeds 4.9 GB. Campus-wide intrusion detection systems are deployed through cooperation with the [[IT Security Lab]].
Port security is enabledon most ports, meaning that users are not permitted to attach a switch to the network and must pay for new connections for all devices. While the $20/month fee for gigabit connectivity is generally thought to be reasonable, many department networks require them to evade this restriction through the use of NAT routing, ARP proxies, and/or NDP proxies. For most public portals, MAC address registration is often required, although some department ports are known to not carry this restriction.
NAT routers are officially banned, largely due to dorm residents bringing their own NAT router, plugging it in backwards, and sending DHCP leases to their entire building. While the ban is generally unenforced unless a problem arises, users are encouraged to purchase additional connections through CNS instead.
