UW-IT offers centralized, managed network firewall service as a for-fee add-on to a campus department’s wired network connection. A network-based firewall plays an important part in a multilevel, multilayer security strategy that should also include other elements such as backup, anti-virus software, host-based firewalls, intrusion detection, and vulnerability scanning.
Firewalls use rules to define what traffic may travel to and from your designated network subnet(s). An example of a common firewall rule is one that allows only traffic to port 80 and 443 on a web server, but blocks access to any other ports in order to help protect the server operating system from unauthorized access. A wide variety of rule options are available.
Details on this service are on the Managed Firewall Service page in the UW-IT Service Catalog.
