Virtual Private Networks (Vpn) For Beginners

In simple terms, a network inside a network is a Virtual Private Networks. This is a form of technology most popular with companies whose staff works independently. Basically what we have here is a utilization of the network already provided by the internet. The internet infrastructure can be used as the network for remote employees to access 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. As a result, security and encryption is further tightened. 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. First, there needs to be a corporate server setup which has the server VPN software installed (and a good router with a firewall). And of course the remote employees would also need to have the client VPN software installed on their PCs. The VPN client software would be used to touch base with the server VPN software to facilitate authentication right after the client machine goes online. The server would check if the client is indeed a valid one, and if it is, then access would be allowed. And once both client and server synergize in this sense, the information that passes to and from this virtual private network would be further encrypted with more security options.

Now that you know VPN in simple terms, it may be time to consider getting a leased line to save even more money. Depending on the distance between the sites, the price of leased lines may vary. A virtual private network does not and in fact is more scaleable.

So if your business has remote employees and requires Intranet access to those with remote offices or secured dial-up connections, VPN just may be what you are looking for.

This is VPN in a nutshell, explained in simple English. 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. So for further reading and research, you should always consider the specific type of implementation – is it site-to-site, remote or secure dial-up? Other interesting topics worth reading include, but are not limited to firewalls, encryption, security, different types of servers and Internet protocol security protocol, or IPSEC.
