Network Firewalls

The Office of Information Technology (OIT) offers a campus-wide central firewall service that enables network security protection for University of Minnesota computer users and resources. A firewall is an access control device that inspects network traffic passing through it and denies or permits passage based on a set of security rules which are configurable by a mid-owner. A firewall policy is a collection of security rules designed to prevent unauthorized electronic access to private and sensitive data and resources stored on networked computer systems.
