VIRTUAL PRIVATE NETWORK (VPN) BASED ON IP SECURITY DESIGN ON TOPOLOGY

Abstract

One way to maintain and improve the quality of service and security on the organization's network at the West Pasaman Regent Library and Archives  Office is to add  VPN functionality. Administrators  always monitor traffic by accessing routers and access points to determine network status. Sometimes the administrator is on a public network and cannot access the router and access point  because the obtained public IP address is dynamic (random). To overcome these problems, the Network Development Life Cycle (NDLC) approach is implemented by combining the L2TP and IPSec VPN protocol system that exists on Mikrotik. A VPN is a private, secure network that uses a public network like the Internet. One of the security foundations of VPN technology is Internet Protocol Security (IPSec). IPSec is a protocol used to secure datagram transmission over TCP/IP networks. This research aims to design and implement a Virtual Private Network (VPN) network system using public networks, which provides advanced security enhancements to the Internet using IPSec
