Full form of VPN: Virtual Private Network
VPN Full Form Name is a virtual private network. VPN is a network that is used for connectivity. It is built by using public cables. A VPN ensures that the respective network is kept safe and private. Private organizations use VPN so that data transmission is limited only to their chosen employees or clients. It is simply a system for connecting to a private network such as the internal network of an organization.
VPN ensures that only chosen and authorized users can access your network. Therefore, it guarantees maximum security in data transmission by emphatically excluding the possibility of any type of data interception. Usually, the internet is used to build a VPN. In a sense, a VPN is a secure WAN (wide area network). Ultimate traffic encryption and virtual tunnel protocols help create a point-to-point connection that is necessary to build a VPN.
Internet service providers give private organizations the luxury of having their own VPN. The protocols used in traffic tunneling, the location of the tunnel endpoint, the level of security, the OSI layer presented to connect a network, and the characteristic of the Site-to-site or network-to-network connectivity are factors that characterize a VPN. The security mechanism is based on confidentiality, sender authentication, and message integrity. Virtual Private LAN Service (VPLS) is a variant of VPN that helps solve problems that the VPN cannot address properly.
