SUMMARY

             

Virtual Private Network (VPN) is one of the commonly used emerging technologies in the field of information technology. VPN help the organization to provide a secure data communication within a network. It uses a public telecommunication infrastructure (Internet) for providing the secure access of organization to its employee. VPN network is known to be very secure as it uses various encryption techniques while transferring the data and password authentication system for accessing the data.

 

A VPN allows you to create a secured connection to another network over the Internet. It can be use to access region-restricted websites and shield your browsing activity from prying eyes on public Wi-Fi.  VPN is a program that creates a safe and encrypted connection over a less secure network, such as the public internet. It works by using the shared public infrastructure while maintaining privacy through security procedures and tunneling protocols.

 

In effect, by encrypting data at the sending end and decrypting it at the receiving end, the protocols send the data through a "tunnel" that is not accessible by data that are not properly encrypted. An additional level of security involves encrypting not only the data, but also the originating and receiving network addresses.

 

When you connect your computer or another device, such as a smartphone or tablet to a VPN, the computer acts as if it is on the same local network as the VPN. All your network traffic is sent over a secure connection to the VPN and because your computer behaves as if it is on the network, this allows you to securely access local network resources even when you’re on the other side of the world. You’ll also be able to use the Internet as if you were present at the VPN’s location, which has some benefits rather than using the pubic Wi-Fi.

 

When you browse the web while connected to a VPN, your computer contacts the website through the encrypted VPN connection. The VPN forwards the request for you and forwards the response from the website back through the secured connection. If you’re using a USA-based VPN to access Netflix, Netflix will see your connection as coming from within the USA.

 

Since the private network connection works by connecting your network to a private server before you can actually access the website that you want to visit, it might create a performance problem in the process. Some virtual private networks might take a longer time to contact the private servers, which might result in a longer time for you to load the website that you are trying to access. This is in fact a common disadvantage that you will see when you use a free VPN service. Also, you might notice that the connection speed when using a private connection is slower rather than using a regular connection.

RECOMMENDATION

All PNP personnel as well as the public are advised to follow the tips in order to take advantage of the benefits of using a Virtual Private Network (VPN), to wit:

 

·         Use VPN when browsing the web on public Wi-Fi;

·         Avoid reprisals and trace-back because of your researching;

·         Using VPN can beat location of based streaming restrictions; and

·         Complete sensitive research without interference.
