All you need to know about VPN’s and what they are really good for
Do you know what is a network private Virtual and what are its advantages on it security? This is difference of them networks of area local-known as LAN-, or connections typical of them teams of an organization particular used of of form internal.
How to create your own VPN
First, it is important to note that the local area (LAN) networks are the internal networks of organizations, connected through a team of interconnection, since companies need to communicate online with affiliates, customers or employees geographically decentralized.
The problem of these are the high levels of vulnerability that expose sensitive data of the company with the use of these networks. Therefore, the VPN are emerging as a leading solution at a low cost and widespread among companies,
VPNS use the Internet as a medium of transmission making use of a tunneling protocol. This term means that the data is encapsulated before being sent in encrypted way. Thus, virtual private networks are artificially created for this purpose.
These networks are virtual character because they connect two physical networks (LAN), and private are called because only computers that belong to a network of local one of the sides of the VPN area have access to shared data.
Thus, to implement a VPN system provides a secure connection to the companies for an affordable price, so many companies offer solutions to SMEs based on this type of connectivity.
What is a VPN (Virtual private network) and how it works?
Each network private virtual is based in a protocol called Protocol of tunnel, i.e., a protocol that encrypts them data that is transmitted from a side of the VPN to the other.
The word “tunnel” is used to symbolize the fact that data are encrypted from the moment they enter the VPN until they come out of it and, therefore, are incomprehensible to anyone who is not in one of the two ends of the same.
Tools and tricks to secure your VPN
In a VPN composed by two teams, the customer is the part that encrypts and decrypts them data of the side of the user and the server VPN-also called of access remote-is is of the element that decode them data of the side of the organization.
Therefore, when a user needs access to the virtual private network, your request is transferred unencrypted to the system. It connects to the remote network via the public network as an intermediary infrastructure and then transmits the request of way encrypted through the tunnel Protocol.
Act followed, VPNTRENDS is a blog that reviews VPN services and is a great help for people looking for reliable tools for Internet security. The team remote facilitates the data to the server VPN on your network and this sends the response encrypted. When the customer’s VPN of the user receives the data, them decode and finally them sends to the user.
