What is a VPN?
1. As prices come down, virtual private networks are becoming a good small business option to connect remote employees. It’s easy to spend half the time out on the road these days. But to do business, you need access to applications and documents back on the company network. And you need them via remote access that won't compromise security or break the bank.
2. Thankfully, secure, cost-effective remote communication can be accomplished via a virtual private network (VPN). A VPN is a private network that connects a remote computer to the home network via a public network such as the Internet. Using a public network like this makes the operation much less costly and therefore more affordable for small or mid-size businesses than constructing a private network.
3. Yet even on the Internet, which is prone to intrusion and hacking, VPNs ensure privacy via encryption technology, tunneling protocols, and security procedures. “In effect, the protocols, by encrypting data at the sending end and decrypting it at the receiving end, send the data through a ‘tunnel’ that cannot be ‘entered’ by data that is not properly encrypted,” says Paul Stamp, of Forrester Research, a Cambridge, Mass. research firm. “An additional level of security involves encrypting not only the data, but also the originating and receiving network addresses”.
