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.
