A perfect Description of Virtual Private Networks

What is Virtual Private Network? connection over a public network (VPN) A Virtual Private Network (VPN) is a network technology that creates a secure network BESTVPN SERVICEMAG such as the Internet or a private network owned by a service provider. .com OME In order to gain access to the private network, a user must be authenticated using a unique identification and a password. An authentication token is often used to gain access to a private network through a personal identification number (PIN) that a user must enter | VPN Protocols There are a number of VPN protocols in use that secure the transport of data traffic over a public network infrastructure. Each protocol varies slightly in the way that data is kept secure IP security (IPSec) Point-To-Point Tunneling Protocol (PPTP) Another tunneling protocol used to connect a remote client to a private server over the Internet. PPTP is one of the most widely used VPN protocols because of it's straightforward configuration and maintenance used to secure communications over the Internet. IPSec traffic can use either transport mode or tunneling to encrypt data traffic in a VPN. Secure Sockets Layer (SSL) and O Transport Layer Security (TLS) O Layer 2 Tunneling Protocol (L2TP) Uses cryptography to secure communications over the Internet. Both protocols use a "handshake" method of authentication that involves a negotiation of network parameters between the client and server machines. A protocol used to tunnel data communications traffic between two sites over the Internet. L2TP is often used in tandem with IPSec (which acts as a security layer) to secure the transfer of L2TP data packets over the Internet. VPN technology employs sophisticated encryption to ensure security and prevent any unintentional interception of data between private sites. All traffic over a VPN is encrypted using algorithms to secure data integrity and privacy. A Advantages of VPN The Low Cost of VPN More Information One way a VPN lowers costs is by eliminating the need for expensive long-distance leased lines. With VPNS, an organization needs only a relatively short dedicated connection to the service provider. https://www.bestvpnservicemag.com/ O VPN Network Scalability The cost to construct a dedicated private network is vast and increases when your organization expands. VPNS eliminate this scalability issue by simply utilizing the public network capacity. It is more remarkable for remote and international connections where VPNS can provide quality services.
