What is a VPN?

Wireless Security: VPN

VPN stands for virtual private network, and is another wireless security measure used. VPN's encrypt information as it is sent via the wireless network. VPN software must be installed on individual computers, and in order to connect to the network, a username and password is required. When used properly, VPN's drastically increase wireless security and is a great security tool if you are connecting to a wireless home network from a public hot spot.

The definition of "VPN" in this tip is far too narrow. VPNs are used in this way but are also used in large corporate settings and have nothing specifically to do with wireless or home networks. Also, in many cases, addtional authentication requirements are in place beyond a simple username/password pair, such as a hardware based challenge passphrase token, software generated encryption key, etc.
