""Ryan Russell" <Ryan.Russell () sybase com>" thus spake unto me: : > Just wanted to find out what other people opinion on 'VPN' as a : >general idea? IMHO, the person who came up with the VPN idea should be : >shot, because in most cased all VPN do is create entry points into your : >network (in most cased right past the firewall and some times in the : >hear of your network). : : Depends... if you've outlawed remote-access entirely, then VPNs : shouldn't be allowed either (remote-access VPNs, at least.) : If you allow people to use modems to get into your network, : then a VPN may be an improvement in security. The basic rule I like to follow for VPNs is that a VPN alone is only used to provide a secured connection between two "networks" that are managed by the same entity and that implement the same security policy. This includes knowledge of all other ingress/egress points on the remote network and how they are protected as well as physical security implementation. In other words, a VPN is only used by itself if a logical remote extension of an existing environment is being created using an untrusted network as transport. If the remote endpoint is another organization, home user, etc. then filtering/proxies are deployed to make sure that only appropriate traffic is permitted to enter our network from the VPN. Remember, this is all a function of the policy requirements of your organization which may be different from mine. -paul
