VPN - Overview of​ Virual Private Networks
Virtual Private Network is​ a​ network within a​ network .​
This is​ very popular with businesses that have people working remotely .​
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 .​
Corporate environments have a​ far greater need for​ tight 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 .​
Only authenticated users can access the​ corporate network and​ the​ data being transferred cannot be intercepted .​
So this VPN (virtual private network) connection is​ being run through the​ internet public network .​
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) .​
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 .​
Once the​ server identifies the​ connecting client as​ a​ valid machine, access to​ the​ network is​ granted .​
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 .​
Finally, there can be a​ cost savings if​ determining whether a​ leased line or​ VPN is​ for​ you .​
Leased lines can increase in​ price based on the​ geographic distance between sites .​
a​ virtual private network does not and​ in​ fact is​ more scaleable .​
(This is​ a​ general statement ONLY .​
It's best to​ consult with your communications broker prior to​ making this decision .​
a​ broker will be able to​ provide much more information when compared to​ speaking with a​ specific vendor)
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.
This article is​ just a​ very general overview .​
You should use this only as​ a​ starting point to​ even determine whether or​ not this type of​ technology is​ for​ you .​
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 .​
Additional areas to​ research would be security, firewalls, encryption, server type and​ IPSec (internet protocol security protocol).
