How Virtual Private Networks Works.



Hey everyone, Sudarshan here and today we'll understand what is a VPN and how it works.


Virtual Private networks or VPN's for short are used today for many reasons, but all of them fall under the same general reason which is Security. Connecting an individual client often a PC to a larger server or provider, now in the past these types of connections were mostly used in business settings when a large employer wishes to allow employees access to a secured internal network over the Internet while work from home or in the field, but it's becoming more and more common now to see them used by even small businesses or even individuals who for a range of reasons wish to keep their activities online secure and private.


Now, the first step of the security process for a VPN involves creating a tunnel protocol which acts as a tunnel or conduit for the information packets being transferred to pass through, it creates a security layer which instantly terminates the connection whenever it detects an intrusion and then reconnects the client back to the server using a different route avoiding the compromised points or the entire previous route altogether the next time around. Some services even utilised highly specified routes which they consider to be lower risk than other ones, usually based on some sort of internally established metrics or a working partnership with the operator.


Now inside this protective tunnel is where data can be found. This data is also encrypted, as one might expect, but on top of this, further efforts are made to ensure that the contents of one's email don't become public, beyond standard encryption, nonlinear transfer method such as utilising multiple routes for the traffic or the introduction of dummy code into the information packet prevents prying eyes from seeing anything but a small garbled slice of the overall pie.


So to summarise, the way a VPN security works. If data transfers happen in basically the same way that all other Internet traffic does, while offering a tremendously higher level of personal protection and the ability to access secure networks from abroad, then there's no downside, right? Let's just use them all the time. VPNs are super cool, although some VPN companies have made utilising their service as easy as double clicking the correct icon and beginning to surf, and they're getting more affordable than ever, some pages and services might not work correctly over a VPN and content loading performance can be affected as well. Since encryption efforts coupled with what can be considered less direct routes can lead to a slower overall experience in many cases, though this can be solved quite easily by keeping another stock  web browser installed on your computer for non-mission critical use and it's also worth noting that many VPN users actually report faster speeds on certain popular sites such as You Tube at peak times, presumably because their traffic is avoiding some of the congestion seen along the other traditional roots. There are some other less easily addressed problems too, though in buildings with shoddy wiring, packet loss can look like the network is compromised, causing the connection to be continually dropped and re established.
