Analytical Models for the Interaction Between Botmasters and Honeypots

This paper presents a study of successful dictionary attacks against a SSH server and their network-based detection. On the basis of experience in the protection of university network we developed a detection algorithm based on a generic SSH authentication pattern. Thanks to the network-based approach, the detection algorithm is host independent and highly scalable. We deployed a high-interacti...

Mobile devices suffer daily threats of various kinds, in particular in a digital form, where users without consent receives and installs malware on their mobile devices via wireless networks, getting their information vulnerable to unauthorized persons. Aiming to learn more targeted attacks on mobile devices, this paper presents a mechanism that emulates services and protocols within a mobile d...

For years, numbers of researches had addressed the serious matters of network attacks, and developed various technologies such as firewalls and intrusion detection systems to prevent the malware attacking. Currently, technologies lack any investigative features because of the network information gathering is too difficult. In this study, we designed a network forensics system, which contented h...

Distributed Denial-of-Service attacks are still a big threat to the Internet. Several proposals for coping with the attacks have been made in the recent past, but neither of them are successful on themselves alone. In this paper, we present a system that helps in the defence in depth of a network from DDoS attacks. In addition to state-of-art active and passive security defences, we propose a h...

Attacks against smartphones are becoming commonplace today, especially since they are connected to the Internet at all times. Current attacks range from worms and botnets [9], to user installed Trojans [8]. New vulnerabilities in smartphones emerge fast particularly since today’s smartphones are based on common software libraries such as the Linux kernel or the WebKit browser engine. In order t...
