Hands-on ethical hacking and network defense has become an essential component in teaching cybersecurity. However, without understanding vulnerabilities in a computer system, it would be difficult to conduct successful network defense in order to prevent intruders in the real world. Therefore, teaching ethical hacking and vulnerability scanning is a key element to the success of cybersecurity curriculum...
It has become a trend that more and more institutions offer offensive techniques in information assurance education. In this paper, up the discussion of network mapping and vulnerability scanning, gaining access to a target via vulnerability exploitation, and maintaining an access to a victim host through HackerDefender rootkit techniques, we propose integrating the hacking techniques into information...
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...
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...
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...
