VPN means Virtual Private Network It is a secure connection between two or more devices over the WWW(World Wide Web).
Why It Needed…?
VPN are used to protect private web traffic from snooping, interference, and censorship. It blocks the location and changed it.
So that every blocked content can be accessed using VPN. It Also hide the original Ip(Internet Protocol) no need to use any other software to do this.
Advantages Of Vpn
Enhanced security – When you connect to the network through a VPN, the data is kept secured and encrypted. In this way, the information is away from the hackers’ eyes.
Remote Control – In case of a company, the great advantage of having a VPN is that the information can be accessed remotely even from home or from any other place. That’s why a VPN can increase productivity within a company.
Online Anonymity – Through a VPN you can browse the web in complete anonymity. Compared to hide IP software or web proxies, the advantage of a VPN service is that it allows you to access both web applications and websites in complete anonymity.
Unblock Websites – VPNs are great for accessing blocked websites or for bypassing Internet filters. This is why there is an increased number of VPN services used in countries where Internet censorship is applied.
Change IP Address – If you need an IP address from another country, then a VPN can provide you this.
Better Performance – Bandwidth and efficiency of the network can generally be increased once a VPN solution is implemented.
Reduce Costs – Once a VPN network is created, the maintenance cost is very low. More than that, if you opt for a service provider, the network setup and surveillance is no more a concern
Encrypt The data – It Encrypt the data and hide it from your Government even your ISP can’t track your activity. It protects you from the insecure data. Some VPN are used 128 bit and 256 bit encryption for the secure connection . So that a VPN connection is Hard to Hack.
How VPN Works ?
Every VPN Has main 3 Components i.e. Security Protocol,Encryption and The Servers.
1. Security protocols –
VPNs use a security protocol that protects any information that passes through the server. This protocol creates a secure connection and also influences the type of encryption the VPN uses. While the security protocols are not as perfect as a real private network (or a physical cable), it comes close. There are different types of protocols that are used for different reasons. If you want to learn more about each security protocol and how they work, click here. In general, though, the most secure protocol is OpenVPN, and it’s typically the best protocol to use.
Encryption goes hand in hand with the security protocol. This feature guards your data by encrypting it. So, even if a hacker or someone else gets a hold of your data, they won’t be able to decipher it. The best VPNs use AES 128-bit and 256-bit. AES stands for Advanced Encryption Standard, and it’s the most common cipher. The majority of VPNs use this, and it’s compatible will all of the main VPN protocols. The numbers 128 and 256 correspond to the key length, and it represents the possible number of combinations. To put it in perspective, the fastest computer would take more than a billion years to come up with all the possible combinations for AES 128-bit. Encryption is a crucial factor when it comes to VPNs. We dive more into encryption and the possibility of VPNs getting hacked in this article.
A lot of times you’ll hear certain VPNs boasting their number of servers. This is because it is typically better to have a wide array of servers and locations.
Usually, when you use the internet, you send your data to a server with a request for a certain website. That server then sends the website information back to your device.When you use a VPN, your data first goes to the VPN’s server, and then the VPN sends it to the intended server.This is important because when you ping a server for a website, you constantly send data back and forth over that connection. If you insert a VPN in the middle, your request for the website goes to the server, but your data only moves between your device and the VPN’s server (which is also through an encrypted tunnel). Therefore, the intended server does not receive any of your information.
This is how VPN users remain anonymous online. This is also how VPNs can change your location to unblock certain websites (more on that below).
The only way your location can be found is if you have a leak (or if the VPN company keeps tabs on you).
How Do I Get A VPN ?
Everyone Can Use VPN their PC as well as Smart Phone.
Only you have to registered the vpn connection providing organisation. Some of them are free and some of the paid VPN you have to chose which you want free or paid .If you you want to go with free vpn then it is not very good for all i suggest that if you are using a free vpn then don’t share a private data it may be hacked .
