RE: VPN and Security

["Nick Duda" <nduda () VistaPrint com>]

Mike refers to CCA (Cisco Clean Access) , CAS and CAM A great solution
that we just implemented. You can write checks/rules and roles based on
anything you want from a client PC. You can check registry, files,
folders, services, installed aps, updates even write your own custom
stuff that enforces end users agree to your VPN/AUP. It gets setup to
automate the process so non-technical VPN users just have to click a
button to remediate the issue.

It's costly, but ensures that what requirements you set are met before
access is granted.

There are also technologies like Cisco NAC (among others) that can check
and
enforce endpoint compliance with you standards (patch levels, antivirus,
etc.). That should help on the user side if you can't force them to use
a
company configured and maintained PC from outside the office.
