Network Services

Network Services

Network services has three major components:
  • Security
  • Connectivity
  • Performance


TNS maintains the internal and external firewalls and filters needed to protect the campus from external threats. Every day thousands of attempts are made from computers on the Internet trying to connect to systems on the UVM network.  Botnets are computers that attempt to ‘phone home’ to the controlling botnet and use UVM systems for nefarious activities such creating and sending spam or viruses or to flood a network with messages as a denial of service attack.  Firewalls and botnet filters are used to prevent and monitor this activity.    

Border Firewalls

Border firewalls protect all of campus from the internet including the academic and adminsitrative computers as well as the residence halls.  No connections are allowed in from the Internet to campus computers.  There are exceptions made for servers with Firewall Waivers such as:


Internal Firewalls

Internal Firewalls protect high-value and sensitive systems from the rest of campus.  These systems include:
  • Peoplesoft
  • Active Directory
  • Credit Card Systems
  • Phone System
  • Network Infrastructure
  • Departments

Internal Firewalls

VPN (Virtual Private Network)

VPN allows UVM affiliates to access on-campus rexources remotely and securely.  Install and use the Cisco AnyConnect software simply by going to, signing on with your UVM NetID and password and following the on-screen instructions.


Internet Connectivity

Network Services manages Internet connections to three different Internet providers - two commodity (commercial) Internet providers and Internet2.  There is a 3 gigabit connection from the commodity providers (1gig and 2 gig) and a 10 gigabit connection to Internet2 with increased bandwith for researchers.
