RE: Good Network Access Control solution using

[Ryan Sumida <rsumida () csulb edu>]

Thank you for the write up, it is very informative.  I forgot to mention 
in my post that our campus does not support the Dorm users at all.  For 
the most part their network is wide open.  They bring in their own 
computers and install/uninstall any OS/software that they want.  I skimmed 
through your paper and noticed all the solutions require client software. 
Is there a product that uses a network based scan (e.g. Nessus) or NIDS to 
validate network access?

Thanks,

Ryan
