Following a pilot this summer, a firewall has been rolled out to a number of residences, and other residences will most likely follow into Autumn Quarter. Currently the active firewalls include Crothers Memorial, and all undergraduate residences except: Kimball, Mirrielees, Wilbur, and Row Houses north of Mayfield Avenue. All residents are being asked to select a level of protection when they register their network connections, even if rules aren't being enforced in their residence yet.

The residential firewalls protect computers against intrusions from outside of the local network by preventing distant computers from initiating contact. They do not protect against computers in the same building and in some cases the buildings nearby, nor do they provide protection when using computers in other locations around campus. Communications initiated from students' computers are not be affected. Students can change their selected levels of protection at any time simply by updating the registrations for their in-room network connections.

The residential firewall is brought to you by IT Services, as a part of the ongoing departmental firewall project. For more information see: http://www.stanford.edu/services/firewall/residential/
