The study of software bugs has long been a key area in software security. Dynamic symbolic execution, in exploring the program's execution paths, finds bugs by analyzing all potential dangerous operations. Due to its high coverage and abilities to generate effective testcases, dynamic symbolic execution has attracted wide attention in the research community. However, the success of dynamic symbolic...
SMT solver which is an automated program analysis technique is increasingly used by Vulnerability discovering platforms, especially in the integer security problems checking. An integer vulnerability discovering platform is mostly decided by the SMT solver. We have analyzed integer security problems and several SMT solvers, such as Boo lector, Z3, STP and so on. We evaluated the ability of the SMT...
Network services face various security challenges such as targeted attacks exploiting security vulnerabilities. Fuzz testing plays an important role in security testing of network service. However, current fuzzing approaches focus on protocol syntax and packet structure, more than multi-phase behavioral interactions between client and server of network service. This paper presents a model-based behavioral...
A survey of dynamic taint propagation (DTP) was provided. It summarized the advantages and disadvantages of several DTP techniques which are based on debugger, binary instrumentation and virtual machine, proposed a series of problems of DTP which are worth to further research and gave the development trends of DTP techniques.
