IMPLEMENTASI NETWORK ACCESS CONTROL PADA JARINGAN LOCAL AREA NETWORK MENGGUNAKAN MIKROTIK

Abstract

This study aims to build a LAN network infrastructure with authentication before connecting to the network and to implement a network security system using Network Access Control (NAC) based on the IEEE 802.1x standard with Mikrotik. This research uses the Network Development Life Cycle (NDLC) method. By using the NDLC research method, it is hoped that it can define the design or development process cycle of a computer network system, especially in the process of implementing Network Access Control (NAC) on a LAN network using a Mikrotik router. The results of this study indicate that the 802.11x protocol can be applied to Network Access Control (NAC) on a computer network using a Mikrotik router, where Mikrotik is used as an authenticator and authentication server (Radius Server) using a user manager. The quality of service with the Quality Of Service (QOS) method for LAN network performance with the application of Network Access Control (NAC) is categorized as Good based on the tests that have been carried out with the results of a delay of 1.92 ms, jitter of 33.3 ms, packet loss of 0%, and throughput of 548 kb. Mikrotik routers can still monitor (monitoring) active hostnames after implementing Network Access Control (NAC) on Local Area Network networks using the 802.11x protocol.
