The Research and Implementation of ARP Monitoring and Protection

摘要

The flaws of ARP protocol, the kinds of ARP attack and the major existing defensive technologies are analyzed in details. Due to the cost of existing defensive technologies is too high; therefore, we design and develop a light-weight tool based on Linux platform. It is suitable for most users because it can detect and defend the ARP attacks accompany with very small extra overhead. Moreover, it is convenient for administrators to manage network. Detailed design and some key codes are presented in this article.
