Freeliveyoung.com - What is VPN & Understanding VPN, VPN Functions - VPN stands for Virtual Private Network, a connection between an internet network with other networks that are private through a public internet connection. Still confused? Simply put it this way, imagine the internet is like a house in which there are people who interact with each other.

Well VPN is like a "room" in the house that makes a separate separation and separation from the internet public. VPN is private/private because it is intended for more serious security issues. Usually used by agencies or companies that want a secure network to use as if connected via LAN. VPN is very important if you do not want our secret or data leaked to others.

Back to its name, why is it called a Virtual Private Network? That's easy, called Virtual Network because it uses the internet network to connect to each other. While called Private Network because of the nature of personal connections and only certain people who can access it. Incoming data on the VPN is also encrypted so that in terms of security and secrets more secure.

Functions As Well As The Benefits Of Using A VPN

So what are the functions and usefulness of the VPN? Simply the benefits of VPN are explained in terms and definitions of creating a private/secure network even though it is on the public internet network. For more details, here are the functions and benefits of a VPN network.

# 1. VPN function:

  • VPNs have a more secure security and secrecy system than a public network. In a VPN, the transmitted data has been encrypted so the secrets are safer from wiretapping. Although someone has been able to tap and steal data from a VPN network, not necessarily he can decipher the data that has been encrypted. VPNs like creating 2 large walls to ensure security and secrecy in the activity on the internet.
  • Using a VPN network will also keep the data awake from any interruptions during its journey. Actually, a data sent from its origin to destination has gone through a very long journey. During the trip, there is a possibility that the data will be disturbed. Either it's broken, corrupted, lost partly even disturbed by a third party. When we use the VPN, the possibility is minimized so that data can get to the destination safely.
  • VPN can be said to have a "checking gate" that guarantees an incoming and outgoing data is genuine and not manipulated by third parties. When a data pass through a VPN network, an authentication check will be performed, either on the data or from that data source. If the original has been proven, then the new data forwarded to the destination.

# 2. VPN Benefits:

  • By using VPN we can connect to certain network eg office, school etc. wherever and whenever through internet public network.
  • As mentioned above, VPN is also a security wall when we connect to the public network.
  • VPN used to create a new network without having to build a separate network. It just needs to create its own space in an internet public network.

How A VPN Works

How does a VPN work so that it can be said to ensure data security and confidentiality? Simply every VPN connection requires a VPN server name. This is the "core" of a VPN network that connects multiple devices in order to connect privately.
If a VPN is used to connect to the internet, then the way it works might be described as follows:
Internet <- -> VPN server <- -> VPN Client <- -> Client
Whereas if used to connect one computer to another computer, it will be like this:
Computer A <- -> VPN Client <- -> Internet <- -> VPN Server <- -> VPN Client <- -> Computer B

To start and connect to a VPN Server, a device needs to be called a VPN Client. It will attempt to contact the VPN Server and verify the user and user password. Once successfully verified, the VPN server will provide a new IP to the user and a new connection will be established.

Advantages and Disadvantages of VPN Use

Everything must have advantages and disadvantages, as well as the VPN. After knowing the definition and how it works, we must also know what are the advantages and disadvantages of using a VPN.

# 1. Advantages of Virtual Private Network (VPN):

  • As an alternative means of creating private networks for companies etc. with a cheaper cost.
  • Make it easy to connect to a particular network even if it is in a remote place.
  • Can open a blocked site/website by hiding the original IP and replacing it with public IP VPN.
  • Avoided from the intrusion of the hands of the third-party rogue.
  • And of course, has better security features in keeping the data to get to the destination safely.

# 2. Disadvantages of Virtual Private Network (VPN):

To keep the network and data secure, special attention is required.
