I had a nasty experience a couple of years back with an
employee using PCA over a VPN. Symantec may have changed
things, but it used to be that if PCA didn't know what
system you intended to connect to, it would scan the /24
subnet you were in looking for hosts willing to accept PCA
connection.
So to anyone who didn't know about the VPN, it looked
like some machine inside our network was scanning customers
of our employee's broadband provider....
Luckily, I had egress filtering in place, so the only
alarm that was set off was mine.

I recommend requiring the use of a VPN by all vendors, then
using the remote access software over the VPN, you can use
VPN policies or IPSec policies to prevent the remote user
from accessing anything but that box.
PCAnywhere is not insecure, but a VPN is secure, PCA can
suffer from MITM attacks, possible compromise of the client
workstation allowing an attacker to use it to gain access to
your network. (Think Remote Exploit + Reverse VNC + PCA)

Hi group,
We used to have PC Anywhere (long long time ago...in the 80's) as a
remote support system. We've moved away from it and now a supplier
wants to connect to his box with it. What position should
the server
be to be secure (network, DMZ, special zone)?
Can you give me an idea on how secure are the last versions
of PC Anywhere?
Can a PC Anywhere connection give them access to our
network even if
the user credential limits the rights to specific
directories on his machine ???
Thanks!
Marty
