vpn tunnelYou’ve heard the term, but what is VPN? And what are some of the specifics of VPN technology? These are some questions you might want to answer before checking out our VPN options, and knowing the answers will make you look smart in the company of your tech-savvy friends.

Virtual Private Network

VPN stands for Virtual Private Network. Let’s break down the each individual component. Virtual relates to the fact that a VPN network is a non-tangible mechanism which facilitates a point-to-point connection by using encryption, a dedicated connection, or a combination of each. The VPN is virtual in the sense that it doesn’t physically reside where you connect to the Internet. A VPN is private because only those who have the credentials supplied by the VPN administrator can connect to it. Finally, it is a network in that the VPN connection is shared by multiple users. That’s the elaborated answer for “what is VPN?”

Simplified, a VPN is a remote connection that allows an authorized group of users to access the Internet via an encrypted connection.

VPN Security Protocols

A specific characteristic of VPN technology is that it operates according to certain security protocols, thereby making it a safer option for Web access. VPN’s prevent personal information from being disclosed by only allowing authenticated access to the server and also by encrypting (think of creating a ciper or secret code) the data that is passed across the network.

VPN’s work on a model of security which includes three primary elements:

Confidentiality insures that those who access the VPN network are protected against attempts to “sniff” personal data. Data becomes unrecognizable gibberish when it is encrypted, and complex keys are required to decrypt the data. This aspect can also reflect the VPN provider’s policy to not log or otherwise keep records of user’s browsing activity.

Authentication means that only those with the proper credentials can access the VPN tunnel. Each time a user attempts to access the VPN their access must be authenticated by multiple measures, beginning with a username and password.

Integrity is used to detect and identify any tampering with transmitted messages. Basically, the integrity of a VPN is an outgrowth of the first two security principles.

Simplified, VPN security safeguards you against tampering and observation of your Internet activities and private data.

Know the basics of VPN

One of the best things about a VPN account from VPNaccounts.com is that you don’t need to be able to explain all the technical aspects of tunneling and encryption to use the technology. A VPN is a bit like a lightswitch. Once the technology is in place, you simply need to turn it on to take advantage of the benefits. If you know the basics, when someone asks, “What is VPN?”, you can give an intelligent answer, but realize that you don’t have to be a technology wizard to use a VPN for added security.
