| The remote node of the VPN is often a single node, perhaps a user connecting from home. Users usually have regular connections to their ISPs, and encrypt information back to their corporate network. Now the security of your VPN is dependent upon the security of a user's home system and the hacker's ability to find that user's IP address, which can be used to hack into the system. With the popularity of home DSL, ISDN, and cable modems on the rise, the chance of this occurring increases.
