Stepping-stone is the most popular way used to attack other computers. Some insiders use stepping-stone to launch their attacks pretending to be outsiders. In this paper, we propose a novel algorithm to detect stepping-stone insider attacks through comparing outgoing and incoming connections. We modify the existing packet matching algorithm by introducing sliding window to make the algorithm more...
Firstly the distribution centers locating and its study progress are introduced, and then drawbacks of the static model locating method are discussed and summarized. The initial conclusion is drawn from single-facility locating method-center-of-gravity method (CGM) as the static model locating method. Combining with the dynamic programming (DP) method, the dynamic optimal distribution center locating...
Stepping-stone attack in network intrusion detection are attackers who use a sequence of intermediate (or so called stepping-stone) hosts to initiate attacks in order to hide their origins. We investigate a number of dynamic programming based pattern recognition approaches and our novel algorithm for detecting correlation and similarity of two connections not only into and out of a single stepping...
