Virtual Private Network (VPN) is used to connect between
private network and a remote network through internet connection. VPN will also
provide encryption for connection that is established between one private
network and a remote network (“Virtual Private,”
2012). There are two types of VPN namely, Site to Site VPN and Remote-access
VPN.
Site to Site VPN are VPN that
allows different LAN in fixed location to communicate over a secure
communication using the internet. There are two types of VPNs namely intranet-based
and extranet-based (“Virtual Private,”
2012).
Intranet based VPN will mean the
company is located in multiple fixed location and they would like to combine
each LAN in the company to form a WAN using intranet VPN (“Virtual Private,” 2012).
However extranet-based VPN will
be referring to building a shared, secure network between two or more network.
However this shared network is unable to access to others intranet. This type
of intranet is used when they would like to communicate with their business
partner in a secure manner (“Virtual Private,”
2012).
However remote-access VPN will be
referring to establishing a secure connection in a remote location. One
of the industries
that require remote-access VPN would be insurance company. It is because one of
they might require their salesperson to be able to connect to their company
server in order to perform adding of sensitive data (“Virtual Private,” 2012).
There are two types of VPN component
are needed in order to perform remote-access VPN. These components are, Network
Access Server (NAS) and the client software. NAS could be a dedicated server or
server that installs multiple programs.
NAS will then require user to provide credentials to sign in.
Following
that, they will run verify the user either using their own checking process or
using authentication server that is located in the same network (“Virtual Private,” 2012).
Client software is need as well
in order for remote-access VPN to work. This software is needed to establish or
maintain any remote VPN connection (“Virtual
Private,” 2012).

Hi Kim Chye
ReplyDeleteI've read your post about Site-to-Site VPN and Remote Access VPN, it was quite a good post and i now know that Site-to-Site VPN allows different LAN in a fixed location to communicate over a secure communication using the internet and remote-access VPN is establishing a secure connection in a remote location.
