As both public and private networks have their advantages, a technique has been developed to combine their advantages. This technique is called a virtual private network (called. Virtual Private Network – VPN). A company located in many centers, using this technique, can have a private network, using a public network for transmission. In particular, although a company uses a public network to connect its sites, this technique restricts packet traffic so that it only travels between the company’s sites. Moreover, if someone accidentally receives such a packet, the Fast VPN ensures that the contents of that packet cannot be understood.
To use a VPN, the company purchases the appropriate set of hardware and software for each of its sites. This stub is installed between the company’s private (ie, internal) network and the public network. Each of these kits must be configured to know the addresses of the company’s other VPN systems. As a result, the software will only exchange packages with these particular VPN systems from the company. Moreover, to guarantee network privacy, the VPN system encrypts each packet before transmitting it.
Features and use of VPN
The term “Virtual Private Networks” (VPN) is increasingly used to refer to the direction in which wide area computer networks are heading. The term is often used to refer to any publicly available network infrastructure within which separate subnets are defined for use by a specific client. The separation of networks dedicated to different clients is basically always logical, the important thing is that the service provider guarantees privacy. According to the above definition, VPNs can be built on the basis of public Frame-Relay, X.25, ATM networks.
Advantages
Ways to implement privacy
The following technologies are used to ensure security in VPN networks:
Communication for multiple protocols
Access networks
To organize cheap and safe access to your own network for users staying outside the company, it is possible to use the nearest Internet provider and set up a tunnel to the gateway in your own company. The tunnel can be initiated by the employee’s computer or by the Internet provider’s Access-Server (so his cooperation is required).
