VPN stands for Virtual Private Network. It allows a user to connect to a network through a tunneling protocol and access internal Internet and intranet websites and e-mail. Virtual private networks allow an employee with a large company to connect to the company’s intranet. It available from the public Internet can provide some of the benefits of a wide area network.
Protocols of Virtual Private Network
- IPsec (IP security)
- Point to Point Tunneling Protocol
- Layer 2 Tunneling Protocol
- SSL (Secure Sockets Layer)
- Transport Layer Security
How does a VPN work?
A VPN hides your IP address by letting the network redirect it through a specially configured remote server run by a VPN host. This means that if you surf online with a VPN, the VPN server becomes the source of your data. This means your Internet Service Provider and other third parties cannot see which websites you visit or what data you send and receive online. A VPN works like a filter that turns all your data into “gibberish”. Even if someone were to get their hands on your data, it would be useless.
Advantages of a VPN Connection
- Secure encryption: To read the data, you need an encryption key. Without one, it would take millions of years for a computer to decipher the code in the event of a brute force attack. With VPN, your online activities are hidden even on public networks.
- Disguising your whereabouts: VPN servers essentially act as your proxies on the internet. Because the demographic location data comes from a server in another country, your actual location cannot be determined. In addition, most VPN services do not store logs of your activities. Some providers, on the other hand, record your behavior, but do not pass this information on to third parties. This means that any potential record of your user behavior remains permanently hidden.
- Access to regional content: Regional web content is not always accessible from everywhere. Services and websites often contain content that can only be accessed from certain parts of the world. Standard connections use local servers in the country to determine your location. This means that you cannot access the content at home while traveling, and you cannot access international content from home. With VPN location spoofing, you can switch to a server in another country and effectively “change” your location.
- Secure data transfer: If you work remotely, you may need to access important files on your company’s network. For security reasons, this kind of information requires a secure connection. To gain access to the network, a Virtual Private Network connection is often required. Virtual Private Network services connect to private servers and use encryption methods to reduce the risk of data leakage.
