Mac address spoofing detection and response system
The patent US12028371B2 outlines a method and system for detecting and responding to MAC address spoofing in network devices. The method involves accessing MAC addresses associated with communications on different ports of network devices, along with their respective timestamps. By comparing these addresses and timestamps, the system identifies instances where a second device is spoofing the MAC address of a first device. The detection criteria include a match between the MAC addresses, differing ports, and a time threshold between the communications. Upon identifying a spoofing event, the system can perform actions such as blocking communication on the affected port, which can be executed by various network devices including switches, routers, and firewalls.
Additionally, the patent describes processes for clearing records associated with the identified MAC addresses after the spoofing event, ensuring that the network remains secure and efficient. The system is designed to operate without user interaction, enhancing its effectiveness in real-time network monitoring. It also includes provisions for accessing additional communication information related to the involved MAC addresses, further supporting the detection and response mechanisms. The method is compatible with authentication protocols like 802.1X, and the implementation can be facilitated through a non-transitory computer-readable medium containing the necessary instructions for execution. This innovation aims to bolster network security by proactively addressing potential MAC address spoofing threats.
