How does VPN work?

VPN hosts redirect your request to a remote server which thus hides your IP address. It means that a VPN server acting as a source provides you data. This way your internet service provider can not find out what websites you have visited when online. What data you send or receive becomes difficult to figure out by third parties. VPN turns your data into blather. If someone gets his hands on your data then he can’t do anything with it as it becomes useless.  

 

Let us walk you through the benefits of VPN.

What are the benefits of VPN?

VPN protects data from external access by encrypting your data online. Unencrypted data is visible to anyone on the internet with network access. Deciphering becomes hard if data is encrypted. 

Protect from Brute Force Attach

To decrypt the encrypted data a encryption key is required. Otherwise, it would take thousands of years for a computer to decipher the data. In case of a brute force attack the hackers and cyber criminals would not decrypt the data. Even on a public network your activities become secure.

Hide Location

To determine your location, standard connections use local servers. Some content on the web can not be accessed from everywhere in the world. Countries block certain websites' access to their citizens. It means that accessing content at home or while travelling is not possible. VPN spoof location thus allowing you access to even blocked websites. Using VPN you connect to servers at different locations.Means data is requested from the server’s location not yours. 

VPN as Proxies   

VPN plays a role as proxies on the internet. Data comes from the demographic location of the server thus your exact location cannot be revealed. Moreover, most VPN providers don't record logs of your activities. That means the record of your activities remain completely hidden.  

Risk of Data Leakage 

People who work remotely need to access files from the office network. Without a VPN third parties can use information in files to work against you. Or they can use this confidential data to harm you. For security reasons, a secure connection is necessary. VPN transmits data in encrypted format thus risk of data leakage is minimal. 

Reasons to Use VPN

Internet service providers set up connections when you turn on the internet. They track your activities on the internet through your IP address. All your traffic reaches you through the ISP’s server. They can log in to find what you are doing online. There is no guarantee that  your ISP is trustworthy. They can sell your data to advertisers or to the government. What if ISPs get attacked by cyber criminals? In both cases, your personal and private data is at risk.

That’s why connecting to public wi-fi is a risky thing. You will never know whether someone is monitoring your traffic or not. Cyber criminals can steal information like passwords, billing information and personal data. 

 

What you should expect from a VPN solution?

There are certain factors you should look for in advance before choosing a VPN solution so that your security may not be compromised. 

Two-factor Authentication

Your secure VPN connection should take a thorough look on who tries to log in. VPNs use a variety of authentication methods. The most common is sending you a code to your mobile device when a password is requested.

Encrypt IP Address

Hiding IP addresses from the internet service provider is the prime job of VPN. Sending and receiving information this way gives freedom from the risk of anyone monitoring your data.

Interruption in VPN Connection

Interruption in VPN connection is directly connected to interruption in secure connection. Excellent VPN services detect this switch and instantly terminate the preselected programs so that data is not compromised.

Cookies Encryption 

Third parties track your personal data, confidential information and other data on websites through cookies. Good VPN connections provide security by encrypting cookies.

 

History of VPN

In the 1960s, the US department of defence recognized the need to encrypt browsing data. With much effort they created a predecessor of VPN called Advanced Research Projects Agency Network (ARPANET). This invention led to the creation of TCP/IP protocol. Link, internet, transport and application were the four levels of this protocol. Local devices connect to the universal network at the internet level. The risk of exposure of data became clear from there. At last in 1933, students from columbia university created swIPe (Software IP encryption protocol). 

In the same year, Wei Xu created IPSec. This protocol encrypts the data packets shared online. As the internet became popular the need for security systems rose. Companies started demanding systems which could hide their confidential data.

In the 2000s, the first VPN was started. The consumer market for VPN started to grow in 2010. Countries like China, Indonesia and Thailand where internet use is prohibited many users use VPN there. High demand for content from geographically restricted areas is the biggest driver for VPN. Certain content is made available only in certain countries. To access this content people use VPN. Thus, hiding IP addresses make you access content from anywhere in the world. 

Conclusion
