In the past few years we have been using the internet ever more frequently Advertisements for VPNs have been bombarded.[ Random Promotional Gibberish] But what actually is a VPN? And do you really need it? I’m Robert from GIGA TECH and now you can find out exactly what VPNs are. Before we got to get what beings like to sell to us on the Internet: what is actually technical encounter a VPN? The expression VPN is initially an abbreviation for Virtual Private Network, ie virtual Private structure. Mostly that means: You build an encrypted – therefore private – network connection a maneuver “thats really not” on the same network. Classic example: You sit at home and want to access the network storage in the power, which is actually simply set up so that you have access from the power. The alter is also possible: You be engaged in the agency and want to access the data at home. With a VPN connection, your own structure can work as if it were in the same network. In countless routers there are several options for setting up your own VPN. Since this connection is encrypted , nobody can see the data containers to areas outside and nothing else goes in and out except for the user’s data this connection is a VPN “tunnel”. The the relation between the bureau and dwelling are frequently set up as separate passages. If I want to use the company or university network, I use the VPN tunnel for everything else I use the “usual tube” on the Internet. But there is another type of tunnel: And that is the one that are likely likes us being marketed. The full passageway. All data that is generated somehow ends up with the VPN provider and then leaves then on the Internet. And why would you need such a VPN? There are many rationales … at least say VPN providers: It be protected against snooping on data At least that used to be a big problem: Numerous websites were in principle unencrypted. If you entered your customer data or payment knowledge there, the unencrypted Data can be read, for example, through man-in-the-middle onslaughts. But as I said, that was a problem a few years ago, back in the mad west of the internet, when everything departed … so in 2013. Up until the middle of the last decade there was just a third of the Encrypted traffic, currently over 90 percentage. If “youre on” these 90 percent of the websites – unmistakable by the lock symbol in the address line – nobody but the subscribers can read this page. So you don’t need a VPN for that. Your own provider can no longer read, even if most of the traffic is on the Internet is encrypted, your Internet provider can still see which sheets you are on drifts around – so at least the provider recognizes the domain. But: Instead of applying the data to your own Internet provider, you simply give it to you other companionships. One can only hope that there is something trustworthy behind it, that it is responsible deals with insurance loopholes or which a secret service may not be overhearing. In addition, you give your own Internet provider the opportunity to do so elsewhere Listening to data: requests to the DNS server, which changes domains into IP residences, are still unencrypted … except for a few DNS-over-HTTPS programmes. And the servers that you ask for are usually with your internet provider. You can counteract this personally and choose a different DNS server. Runs in the network provides. Anonymity on the Internet That is basically correct for the time being: Everyone Communication can no longer be connected to my private internet row will. Instead, they are associated with the VPN provider’s internet line. And as long as the VPN provider doesn’t enter the traffic, that’s no problem. But: do you really know that exactly? GeoBlocking can be bypassed. Let’s get to the reason why VPNs are really squandered: Geo blocking can be bypassed will. That signifies I’m on vacation and still want to access the Netflix library from Germany access: “Whos working”. Or vice versa: Am I in Germany and want to watch BBC content or YouTube Videos that are only available in the United Regime. Simply select a suitable VPN endpoint and the wild rumgestream can begin. More serious lesson: You are in a country where freedom of expression is not has top priority and tries to silence other opinions by blocking the network. Here VPNs can enable access to blocked material, i.e. as long as the VPN services themselves not be locked. VPNs are used a lot … although you might not need them at all. how do you see it? Do you use a VPN service? Write it in specific comments !.
