I was surfing on the net one day and stumbled onto one with a slick 
user I/F where you can watch the net traffic & just hit a key to take 
over the session.  I'll have to dig up where I saw it (I had to 
re-install Netscape & lost my bookmarks). 8^(  I think the commercial 
version is available for a couple of hundred dollars.  

Authentication (even encrypted one-time pad authentication) alone isn't
worth much.  Strong authentication *plus* solid encryption is what I would 
recommend to anyone who is serious about protecting their company from 
the hazards of connecting to the Internet.  I would look for fully encrypted 
links.

>From the what-it's-worth department 
- When I was doing a firewall evaluation a while ago, the only firewall 
vendor that had a solid authentication/encryption scheme was V-ONE.  
They had user-friendly fully-encrypted links (user->firewall & 
firewall->firewall).  Virtually transparent to the users too.  If I 
remember right, their number was (301) 838-8900.

But, I digress...

Best Regards,


Frank
