Many approaches have been proposed to detect stepping-stone intrusion, but few of them can effectively be resistant to intruders' manipulation, such as chaff perturbation, and time-jittering evasion techniques. In this paper, we propose a new approach to not only detect stepping-stone intrusion, but also resist intruders' chaff attack evasion through TCP/IP packet cross-matching and random walk. Unlike...
Traffic flow measurement is of great importance to ISPs for various network engineering tasks. An interesting problem is that how to determine the minimum number of links by monitoring which one can obtain the traffic flows of the whole ISP network. Previous works view the problem as Vertex Cover problem. They suffer from high time complexity and redundant monitoring. Different from these works, we...
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 researchers do not distinguish stepping-stone detection and stepping-stone intrusion detection, thus introduce more false positive errors in detecting stepping-stone intrusion. Those approaches proposed to detect stepping-stone intrusion are vulnerable to intruders' evasion. In this paper we analyze the problems of the current model used to detect stepping-stone, and propose a new model based...
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...
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 an outgoing connection to determine if a computer is used as stepping-stone. In this paper, we present four models to describe stepping-stone intrusion. We also propose the idea...
DDoS attack is one of the major threads of todaypsilas Internet. Defense against spoofed IP addresses is an efficiency way to mitigate the damage caused by DDoS attacks. HCF proposed by Haining Wang et al. can throttle most attacks while the filter being trained entirely. However, due to the growing of applications current network carried, the network trafficpsilas behavior has taken much more changes...
In this paper, we present an architecture of ontology-based distributed simulation on grid (ODSG) which facilitates life-cycle management of large-scale distributed interactive simulation on the grid computing environment. The architecture aims at some further solved key technologies for M&S (model and simulation) and new simulation pattern on open, complex, large-scale distributed grid environment...
