RE: [Full-Disclosure] Good Network Access Control solution using

[Ryan Sumida]

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
