In simple terms, a network inside a network is a Virtual Private Networks. For businesses whose employees work remote, this technology is often utilized. The Internet already provides a network on its own, and this is a way for companies to further utilize this network. The corporate systems needed by employees who work remotely is accessed through the main housing provided by the Internet.
In the corporate setting, air-tight security is paramount in today's environment. As this necessity is the mother of invention, the VPN (virtual private network) was created to serve as a network within the Internet connection. In short, you get more security options at your disposal. Only authenticated users can access the corporate network and the data being transferred cannot be intercepted.
While the Internet is a public network, it is indeed possible to sustain a VPN (virtual private network) within it.
So how exactly does this process work? First of all, you need a corporate server replete with the requisites of a good server setup - including a firewall and fully installed server VPN software. The second ingredient would be client VPN software installed on the computers of the remote employees. After the client computer goes on the Internet, the VPN client software would communicate with the corporate VPN server and begin the authentication process. Access would then be granted after the server is able to successfully identify the connecting client as a valid user. In essence, this is the recipe for a hard outer shell of protection and encryption, and after access has been granted, information can pass to and from the virtual private network freely and safely.
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.
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.
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.
