Firewall Service
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. 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.
Firewall service is available to all University departments on the Twin Cities campus. Departments must be on their own individual network(s) and their resources (e.g., jacks, VLANs, etc.) associated to a Management Identification group (MID) in Service Gateway. If your department has not been migrated to the Service Gateway, contact the Service Gateway Migration Team.
