Chinese hacker communities are of interest to cybersecurity researchers and investigators. When examining Chinese hacker communities, researchers and investigators face many challenges, including understanding the Chinese language, detecting variations in topic evolution, and identifying key hackers with their specialty areas. Therefore, we are motivated to develop a framework for analyzing key hackers...
In order to enhance the ability of software defined network (SDN) proactive security protection, this paper puts forward a path hopping based SDN network defense (PH-SND) technology. PH-SND technology models the path hopping problem as a constraint solving problem, and utilizes satisfiability modulo theory solver to obtain multiple paths, which satisfy overlap and capacity constraints. According to...
In Windows kernel drivers, different function paths will be called according to the DeviceIoControlCode parameter in DeviceIoControl request. In order to achieve high-coverage security testing of these function paths, a new testing method using symbolic testing is proposed in this paper. With the automatic detection of Dispatch routine, symbolic testing is used to analyse the Dispatch function, walk...
