THE FUNDAMENTAL PROPERTIES OF THE VPN
Understanding what a VPN is is incomplete without understanding its key properties: encryption, authentication , and access control. These three criteria distinguish a VPN from an ordinary corporate network that operates on the basis of public connections. Implementing these properties makes it possible to protect users 'computers and organizations ' servers. Information that passes through unprotected channels becomes invulnerable to external factors, eliminating the possibility of its leakage and illegal use.
