Hello Security Folk, 

Looking for a network solution to mitigate the virus/worm problems in our
university dorm network.  Has any one company moved ahead of the pack in the
port based NAC market?  I'm not sure if this is the best way to go but in
theory it would solve some of our problems.  At the moment our IPS is
blocking over 90,000 attacks/hour from the dorm area alone! 

A solution similar to Perfigo's CleanMachine product is what I have in mind
but with 802.1x support.  When end-users would like to get on the network
they start in a temporary restricted VLAN.  The system will then be scanned
(Nessus scan , etc.)  for vulnerabilities defined by the security policy.
If compliant then the mac is granted network access and the port is then
changing to a non-restricted VLAN.   If non-compliant the mac is put on
quarantine list and the port is then set to "jailed" VLAN.   

Anyone know of a good product that can do this or something similar?   

Regards, 

Ryan
