More and more intruders are used to using stepping-stone to launch the attacks on their interested targets because exploiting stepping-stones can hide them deeply and make them feel safe. Clustering-Partitioning approach was proposed to detect stepping-stone intrusion and resist intruders' evasion. The biggest issue of this approach is that it mines network traffic in a very inefficient way. Double...
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...
