What is virtual private network – VPN – and why is it so much talked about? Lately, this term has appeared in every conversation about the Internet. And for a reason, there was a time when VPN technology was a high-tech novelty. But today it is a necessary tool. Basically, VPN technology protects your online privacy. So, what is a VPN and how to use it?
In this guide, you’ll find everything there is to know about a VPN. And by the end of the article you will understand the issues related to this technology.
What is a VPN?
VPN stands for “ Virtual Private Network ”, which literally translates to “virtual private line”. In particular, information exchanged on public networks such as free Wi-Fi has risks. Such as eavesdropping and falsification. And it is not recommended to exchange personal information and other information that could lead to serious risks.
Therefore, I would like to consider using VPN. By setting up a virtual leased line on the Internet and exchanging important information after securing a safe route, it is possible to protect important information from threats such as eavesdropping and falsification.
Imagine when you’re trying to drive on an unsafe road. It is dangerous to walk there by yourself. But if you have a taxi that will take you to your destination, you can pass safely. A VPN is equivalent to this taxi, and is a mechanism that enables safe information communication while protecting against various risks.
What does a VPN do?
In simple words, a VPN connects your computer or phone through an encrypted virtual tunnel to a remote server through which you access the Internet. This server can be located anywhere. Your ISP may know that you are using a VPN, but not for what purpose. For the authorities and the sites you visit, you become a foreign user.
How VPN works?
A VPN is a Virtual Private Network where your data remains protected in transit. When using VPN software, do not connect directly to the internet as usual. You first connect encrypted to the VPN provider, who in turn forwards you to the Internet. Your data will be anonymized. Because your connection request goes through a server of the VPN provider, you as the user will be assigned a new IP address. This protects your actual IP address, which is used to identify your device. Your request to the Internet can hardly be traced back. The virtual private network makes your computer or laptop invisible.
What is a VPN tunnel?
The image of the “tunnel” fits in well with the way the VPN works: outside a road tunnel, nobody can observe or influence the traffic inside. Even with VPN connections, nobody else can see the transmitted data because the connection is encrypted. An attacker can recognize that a connection is being established via this tunnel, but he can neither see what is being transmitted nor where.
Advantages and disadvantages
What are the advantages or benefits of VPN?
The main purpose of using a VPN is to improve security, but there are other benefits to a VPN as follows.
- Peeping on wireless networks such as free Wi-Fi and reducing the risk of tampering
- You can build a pseudo LAN regardless of the physical distance
- Since access is anonymized, there is no need to worry about the IP address being known to a third party.
- Achieves security close to that of a leased line at a much lower cost than a leased line
What are the disadvantages of VPN?
VPNs have many advantages, but they are not without their disadvantages. In order to understand “What is a VPN?”, You need to understand the disadvantages as well.
- VPN doesn’t mean perfect security
- The VPN server you connect to must be reliable
- You can prevent snooping with VPN, but you cannot detect malware.
- Satisfactory communication speed may not be obtained
- Mobile devices can consume a lot of battery
It is said that it is not suitable for communication that requires bandwidth guarantee because it may become a bottleneck by using VPN.
