You can implement nac with an ips so in case that the ips detects a virus
worm etc its talk to the switch and the switch configures the port in a
quarntine vlan etc, check the products of enterasys they do that. The
probelem is that its not cheep.

With nac you can get what is called Fw per port. And it's a modulaer
solution.

Cheers

That does sound like something the NAC can help with. The NAC does let you
pick and choose what features you want to implement. I have not personally
done a NAC install but I do work for a company that does a fair number of
them. I am not sure if NAC will help you purge an existing virus problem.
The NAC is a technical means of enforcing policy that is typically written
into AUP's but is difficult to enforce, especially for home users with VPN
access or laptop users with local admin control.

Well we have the downadup worm floating around our network and are slowly
trying to deal with it.  Our environment has a lot of users who are local
admins so they basically are allowed to download anything here and at home.
I wanted a way to keep them off the network unless they have patches and an
AV solution.  Many users only pull out their laptops every couple of weeks
so obviously the update server isn't reaching them.

Are you sure NAC is the way to go for your issue? An IPS may be a 
better option to keep the spread of Malware down. NAC can be 
expensive, messy to implement and time consuming, it has it's place 
but I don't know if your requirements would warrant it. Can you add a 
little more information to your issue?

Hey all was wondering if anyone had any experience with deploying or 
maintaining a NAC?  I'm looking for recommendations, advice, gotchas, 
etc...

Having some serious malware issues in a place that doesn't have patch 
management and I'm looking to turn to a NAC to help bring the network 
under control.....advice?
