Nowadays a VPN is a cost-effective, reliable and publicly available remote access solution. Whatever the distance, a VPN provides connection anywhere in the world and the safety of the most important data transfer.
A VPN (Virtual Private Network) is a logical network created within another network such as the Internet. Despite the fact that communications are made over the public networks using insecure protocols, by encrypting the data exchange channels get closed from prying communication.
A VPN allows you to combine two or more offices of the organization into a unified network, which will have a unified address space LAN, unified numbering of the corporate telephony, video conferencing possibilities, etc.
The main advantage of VPNs is that the VPN connection is full of value. For a computer and for all the programs there is no difference whether you work through a VPN or through the usual channel. When you do not have access to any site, you can use a proxy server. But not all the programs are fully functional with proxy servers, for example, the torrents may have many problems. But there should not arise any problems with a VPN.
Since the data transmitted on the VPN-connection, is encrypted using https and other safe protocols, the addresses used are protected from viewing from the outside. Only the external IP-addresses are seen on the Internet. This is particularly important for corporations with internal IP-addresses, as administrative costs are excluded to change IP-addresses for remote access via the Internet.
Virtual private networks have several advantages over traditional private networks. One of them is economy. With VPNs enterprises manage to at least partially restrict the growth of the number of modems, access servers, dial-up lines and other technical means that organizations must implement to provide remote users to access their corporate networks. In addition, VPNs allow remote users to access network resources of the company and through the local telephone line.
There is a number of economic benefits of using a VPN such as:
* Free intra office phone calls;
* The possibility of the centralized use of the Internet;
* The possibility of the centralized use of local, long distance and international telephone services;
* Saving for connecting external communication services in each office;
* Saving for highly qualified network administrators in the office.
The other great advantages of VPNs over traditional private networks are flexibility and convenience. These advantages of virtual private networks are due to the fact that they unlike traditional networks can provide remote access to the resources of any authorized user who has got the connection to the Internet. VPNs allow partners to easy access the enterprise network resources through the Internet, which helps to strengthen alliances and improve competitiveness. This could be difficult to achieve by traditional private networks as businesses that are wishing to share network resources, often have incompatible systems. Particularly, this problem occurs when a large number of organizations, such as a major retailer and its distributors want to work together over a network. We recommend to test a few free of charge VPN solutions before switching to a paid one..
As for the disadvantages of a VPN, probably, the main one is the need to create a new network interface. Data protection issues, lack of reliability and performance, and the lack of open standards hinder the wide distribution of the virtual private networks.
For most Internet technologies, the security issues for data transmission are the most important. And virtual private networks are no exception. For them, the main problems relate to user authentication using passwords and protection of the encrypted VPN-channel (tunnel). In addition, network administrators must carefully choose the methods that help users get access to virtual private networks.
