Many people may need VPN explained in order to understand how this private data network actually operates and to get comfortable with using it when working out of the office. VPNs, or virtual private networks, are virtual paths whereby companies can communicate and exchange data with remote locations, using a private, secure and speedy method.
VPN And Your Internet Connection
Using the Internet, a public network, a VPN can be set up between two or more locations. The setup uses what is called tunneling mode encryption, which allows a secure connection to plow straight through all the other signals out there and creates a secure path for files and data to travel through. Security measures ensure that only those authorized to access that connection do so, and those who try to access it without the right permissions will be met with frustration and failure.
Special software enables a remote workstation to start talking with the host's server via the Internet connection. The remote computer will first try to speak to the server using that tunneling technology. Once the host computer verifies that the remote computer is indeed a viable member, it creates a connection between the two.
Once the connection has been established, the host computer can send or receive data with the remote computer. The data is encrypted so that no outside parties can retrieve the information. While the data is being transmitted, the encryption is in place, but, once it reaches the server, it will be dispersed and passed on to the remote computer.
Types Of VPN
There are two kinds of VPN-Site to site Intranet and remote access. Site to site VPN is better for physical locations, such as several computers linked to a network and all are located in a large building, or several buildings linked together. Remote access requires a single VPN and works for employees working from home or on the road.
Many people worry about the security of a VPN because the data exchange is taking place on a public network. While there are always some risks associated with transferring data remotely, VPN programs and connections are still considered secure enough for most companies. However, the risks grow if the remote computer is connecting through a public Wi-Fi or if multiple computers are all trying to function on a different VPN connection.
Can VPN be loaded on BlackBerry devices? Some BlackBerry models natively support VPN, while others might not need it, depending on what you're trying to do.
The benefit of a VPN can range from cost savings to enabling company expansion. It all depends on how you use VPN solutions to service and grow your company.
