Abstract

IP address spoofing and MAC address spoofing attacks, IP spoofing and MAC spoofing respectively, have increased the difficulty of detecting and containing malicious actions from users within wireless networks. This paper presents a tool for detecting and blocking IP spoofing and MAC spoofing attacks on a wireless network using the IEEE 802.1X protocol. For this purpose, our tool uses a combination of information obtained in the analysis of logs and information of the Radius server user database. This information is also analyzed in conjunction with information from the ARP table and TCPdump logs of the routers.
