VPN (Virtual Private Network) Explained

VPN (Virtual Private Network) Explained

VPNVPN accurately stands for the virtual private network. With a VPN, all your traffic is carried inside an encrypted tunnel as it makes its way through the public internet. You don't access the destination until after you've reached the end of the VPN tunnel.

Why VPNs are popular is because they can be used to anonymize and encrypt internet traffic. Governments, ISPs, MITM Attackers, and others can not see what's inside a VPN and also not even be able to find out who is using it.

Why VPNs Are Used

VPN might be used is in work surroundings. A mobile user who needs access to information from a work server might be given VPN credentials to log in to the server so that he can access important files.

Other types of VPNs include site-to-site VPNs, where a local area network is connected to another local area network, such as satellite offices connected together in one corporate network over the internet.

Probably the most common use for a VPN is to hide your internet traffic from ISPs, websites or governments. Sometimes, users who are getting files illegally will use a VPN, like when accessing copyright material through torrent websites.

VPN Requirements

VPN implementations are software-based, as with Cisco's VPN client and server software, or a combination of hardware and software, like Juniper Network's routers that are compatible with their Netscreen-Remote VPN client software.

Home users can buy a service from a VPN supplier for a monthly or yearly fee. These VPN services encrypt and can anonymize browsing and different online activities.

Another type is SSL (Secure Sockets Layer) VPN, which allows the remote user to connect using just a web browser, avoiding the need to install specialized client software. There are pros and cons to both traditional VPNs (typically based on IPSec protocols) and SSL VPNs.
