In this paper, through the analysis of the ARP protocol works, it discusses ARP protocol AR P virus are two common attacks from the IP address to the security risks that exist in the physical address resolution process, and then analyzes in detail, and then introduces the AR P Find virus source and virus removal methods, and finally putting forward effective measures to guard against AR P virus.展开更多

To prevent man-in-the-middle and denial of service attacks caused by an address resolution protocol bug in an SDN-based cloud center, this study proposed a Bayes-based algorithm to calculate the probability of a host being an attacker and further presented a detection model based on the algorithm. Experiments were conducted to validate this method.展开更多
