Firewall Modifications

« View all services

IT Services operates an internet firewall in order to facilitate and enhance network and computer security. This service operates in a mode where all internet access is denied by default and is allowed only by exception.

As an example, Web browsing (http) has been allowed as an exception. If you are trying to access this service on a non-standard port (registered) it will be blocked.

While many common network protocols are configured to work across campus, most network ports are blocked. Exceptions can be made with a valid academic or business rationale, and are considered on a case-by-case basis.
