Re: how prevelant

[Brian Ford <brford () cisco com>]

Ron,

I'm only seeing really small business or academic environments even trying 
to do this.  Most are unsuccessful.  More and more often ISPs like 
Cablevision and their Optimum Online service are blocking  all domain (as 
well as SMTP) traffic at the edge of their cloud.  I've heard from people 
outside that ISP that they are considering blocking this traffic within 
their cloud.

Regarding VPN access I see everything including tokens, various types of 
Smartcards, Active Directory integration, our ACS (AAA server), and yes 
even PKI being used somewhere.  I think the issue of this space is that 
there are multiple ways to do it and the definition of ease of use varies 
from person to person.

Remember healthy paranoia can be your friend.

Liberty for All,

Brian
