A Virtual Private Networks would signify a network inside another network. This is a form of technology most popular with companies whose staff works independently. So in essence, we are looking at the network provided by the World Wide Web used in a new and creative way. The framework of the Internet, in effect, is used by the employees working remotely to get into their corporate systems.
All corporate entities feel the need these days to ramp up security. This is achieved by creating a VPN (virtual private network) on top of the normal internet connection. This type of connection allows for greater security and encryption. This makes it impossible for anybody to stop data from being transferred and only allows network access to those authenticated users.
So as you can see, the VPN (virtual private network) is a private network inside a public one, being the one created through the Internet.
Two components are needed to make this scenario work. The first ingredient is the corporate server, set up in such a way that there is a firewall included with the router and the server VPN software already installed. The next would be to have the client VPN software installed on the remote employees machines. Once the client machine is on the internet, they would use the VPN client software to communicate to the corporate server VPN where authentication occurs. The server would check if the client is indeed a valid one, and if it is, then access would be allowed. From then on all information to/from the client to the server is traveling along this virtual private network and is protected by the additional layer of encryption and security provided.
One last benefit you can enjoy from a VPN or leased line would be additional savings. Leased lines can increase in price based on the geographic distance between sites. This is the opposite of a virtual private network where gauging the price can be done more realistically.
VPN is definitely a viable option for businesses small and large that have remote employees, need site-to-site access with remote offices or secure dial-up connections.
However, we are just scratching the surface of this fascinating topic. This is not to be mistaken as expert advice - rather, it is an article written to help you get a jump on your research on this topic and help you learn the basics. During your evaluation of this technology, you should consider what type of implementation your looking to do; remote access, site-to-site, secure dial-up. We strongly recommend that you read up as well on firewalls, encryption, security, different types of servers and Internet protocol security protocol, or IPSEC.
