Analisis Address Resolution Protocol Poisoning Attack Pada Router Wlan Menggunakan Metode Live Forensics

Nowdays, the development of technology makes technology a necessity for almost everyone.Various kinds of jobs can also be connected through a technology called the internet network.because it’s easy to use, some businesses and agencies are already using wireless local areanetwork technology, but most of them pay less attention to data communication security onwireless networks. One type of attack on on Wireless Local Area Network with open access is theaddress resolution protocol poisoning. By using it, attackers can find the data frames and modifyor even stop the internet traffic, because the data studied is in the form of volatile data that canbe found only in RAM storage or on network traffic, so the attack in this case can be analyzed byusing the live forensics method. Volatile data is temporary and will only exist when the system isstill on, so that digital evidence information and the behavior of the attacker who carried out theattack can be identified by using live forensics method. There is detection in this study using theIntrusion detection system Snort application which will send alerts when the system attacked
