What Is VPN?


VPN is an acronym for Virtual Private Network. With such network, you will be able to provide security and privacy to both public and private networks such as the internet, Hotspots and WiFi. Users of VPN are able to receive or share data through shared or public network as if their systems have a direct connection to the private network. Today, both individuals and corporations are using VPN in order to protect sensitive information as the internet has become one of the most acceptable means of sharing information among people. Face-to-face interaction has given way to virtual interaction. VPN helps to increase privacy because the IP address of the VPN provider is used to replace the initial IP of the user. With this service, users are able to utilize the IP address of any city the service provider offers. For example, with the service, you can appear to live in London or any other cities offered by the provider while in actual fact, you are living in San Francisco.

Security of data is one of the major reasons why many corporations and individuals are making use of this network. However, it can also be used for the network management benefits it offers users as well as for its functionality. Today, hackers are becoming more and more sophisticated in carrying out their evil acts. There are now a lot of easy means through which data traveling to a network can be intercepted. Two easy means through which information can be hacked are Wifi spoofing and Firesheep. VPN is designed to protect data on the internet  just as firewall protects data on the computer. With VPN, online data transfers are encapsulated by VPNs with the use of advanced encryption protocols and secure tunneling techniques. Owing to the activities of hackers, most intelligent computer users will not connect their computers to the internet if they do not have an up-to-dated antivirus and firewall. Development witnessed in the internet technology comes with some security threats. This highlights the importance of VPN owing to the increase reliance on the internet technology. The use of this network prevents the hijacking of the connection and loss of data. It is preferred to proxies because all traffic is protected.

Apart from security of data, VPN can also be utilised for its functionality. Employees are allowed by some VPNs to access a corporate intranet securely outside of their offices. With some VPN, offices of a business, corporation or organisation located in different areas can be connected securely in such a way as to create a cohesive network. VPNs can also be used by individuals to protect their wireless transactions. They can also use it to overcome geo-restrictions and censorships. They will be able to connect to proxy servers in order to protect their locations and personal identity. However, you should bear in mind that in order to guide against the circumvention of their geo-restrictions, some websites block access using known VPNs.

Creating a VPN

Establishing a VPNs is not difficult because the process is straightforward. Sometimes, you may be required to enter only your server address and username. VPNs can be configured with even dominant smartphones with the use of L2TP/IPsec protocols and PPTP. PPTP VPN connections can be configured with all major operating systems. However, while L2TP/IPsec protocol requires certificate download, the OpenVPN requires small open source application (OpenVPN).
