What Exactly Is VPN, And Why Do I Need It?
More and more employees report that they do their office work from home. They frequently use a VPN connection for this. VPN is an abbreviation for virtual private network. Many people have heard of VPN, but only a few understand it and how it works.
What Exactly Is A Vpn?
A VPN is a private network that connects to a public network. These are computers linked to a public network, most commonly the Internet in layman’s terms. This means you can access your private or local network while travelling. It’s called virtual because it doesn’t require a separate physical connection, but it can use an existing network.
There Are Numerous Benefits To Using A VPN:
- A virtual private network allows networks and clients worldwide to communicate.
- A VPN provides a secure connection over an insecure network through proper encryption. As a result, it provides you with greater security.
- Compared to other methods, such as remote connections, it offers up to 80% cost savings.
What Is The Purpose Of A VPN?
A virtual private network is primarily will use when you require access to a network you are will not directly connect to. VPNs are mainly used in business to allow employees to work securely from different locations or the office at home. However, in the private sector, you can use a VPN for a variety of purposes:
VPN – Increased Privacy And Security
With a VPN, you can browse anonymously, hide your location, and encrypt data sent and received. For example, you can avoid targeted advertising.
Bypassing Local Lockdowns
With a VPN connection, you can access Netflix, Amazon Prime Video in any other country of your choice anywhere in the world. Certain apps only work in certain areas. So you can pretend to be in a particular place.
Search engines like Google or social networks like Facebook or Instagram are blocked or monitored in some countries. With a VPN connection, you can also remove national blocks or filters in a country.
What Are The Requirements For A Vpn?
When using a virtual private network, you should pay special attention to the following aspects:
Security is often the central factor that matters. Therefore, you should consider what the VPN will use and what security features it should offer. For example, should it only protect against scanning using the IP address, or should it also protect against tracking by organizations and network authorities?
Surely one should not forget about performance. Complex encryption methods are secure, but they come at the cost of speed because they require a large amount of computing power.
When choosing the technology, you should pay attention to open standards so that you will not always tie to a manufacturer for the necessary extensions. The network must also be scalable, allowing a more significant number of users and bandwidth if necessary.
How Does A Vpn Work?
A tunnel will create when using a virtual private network; a tunnel will begin, i.e. a protected connection through which your data to a remote server operated by the VPN provider. The remote server then sends 5us data to the source you want to connect to. For example, it can be a website or a third-party application on the company’s server. In the same way, you sent the data; you will receive the required data again: through the tunnel.
What Types Of Vpn Exist?
A distinction will make between three different types of virtual private networks.
Site To Site (From The Vpn Gateway To The Vpn Device)
This type is primarily will use for networking multiple business locations. Different companies will connect to integrate certain services of other companies into their network or offer services to business partners or suppliers. Several local networks of different branches will interconnect to form a network. Instead of using a rented line, which usually incurs high costs, will use the Internet’s corresponding connection. An additional variant of this is the extranet VPN.
Site To End (Vpn Gateway To Host)
The goal of every Site to End it should be to enable the most secure access to the company network with the least possible technical and financial effort. You can use this type, for example, if your sales or head office employees need to access the company network. A VPN client must install on the respective employee’s computer to establish a VPN tunnel to the network.
End To End (Host To Host)
Here two servers will connect through different locations. Must install the appropriate it software on both sides. A typical application area for this is, for example, remote desktop, i.e. running application programs on a server which are then operated and display on another computer.
VPN not only offers the possibility to connect to a company network. It can also establish an encrypted connection to an endpoint in another country. For example, authorities can prevent censorship and espionage.
