PPTP (Point-to-Point Tunneling Protocol) is a network protocol used in the implementation of Virtual Private Networks (VPN). New technology for creating Virtual Private Networks (VPNs), developed jointly by Microsoft Corporation Newer VPN technologies like OpenVPN, L2TP, and IPsec. Even though PPTP is less secure than OpenVPN, it is faster and uses less CPU resources. support from Windows, it is widely used on Mac and Linuxplatforms because of speed and compatibility.
PPTP is a network protocol that allows transfer security data from the remote client (client that is far from the server) to the company's private server by creating a VPN via TCP / IP (Snader, 2005). This protocol was developed by Microsoft and Cisco. PPTP network technology is the development of a remote access Point-to-Point protocol issued by the Internet Engineering Task Force (IETF).
PPTP is a network protocol that converts PPP packets into IP datagrams so they can be transmitted via internet. PPTP can also be used on LAN-to-LAN private networks. PPTP has existed since in the Windows NT server operating system and Windows NT Workstation version 4.0. Computers that run with the operating system can use the PPTP protocol to securely connect with the private network as a client with remote access via the internet.
PPTP can also be used by computers connected to the LAN to create VPNs via LAN. The main facility of using PPTP is being able to use a public-switched telephone network (PSTN) to build a VPN. The development of easy and low-cost PPTP to be used widely is a solution for remote users and mobile users, because PPTP provides security and encryption of communication through PSTN or the internet.
