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. The reason is that intruders can be protected through a long connection chain involving some compromised computers called stepping-stones. Some intruders even manipulate a stepping-stone to evade stepping-stone intrusion detection. Intruders' evasion makes detecting stepping-stone intrusion more difficult. In this paper, we propose...
Most network intruders launch their attacks through stepping-stones to reduce the risks of being discovered. To uncover such intrusions, one prevalent, challenging, and critical way is to compare an incoming connection with outgoing connections to determine if a computer is used as a stepping-stone. In this paper, we present a way by using signal processing technology-correlation coefficient, such...
