I have 2 remote users at static locations connecting to our network via vpn. The remote vpn clients are set up in to establish a connection automatically as soon as the remote user boots. I have SUS push patches out to the clients and virus signatures every time the client connects.
My concern lies within those remote users. They are computer illiterate to say the least and am always wondering if one of them is going to contract a virus via email, and have it propagate to our network.
We have a Watchguard firewall with vpn which the remote users connect through. No firewalls on the remote user sites.
One client is running Windows 2000 Professional, the other is running Windows 98.
Are there any other obvious precautions I should take to protect my network from a virus getting through the vpn tunnel ( other than upgrading the Windows 98 client)?
any suggestions appreciated
