VPN - Overview of Virtual 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).
