A virtualization-based method for analysis of Cisco IOS

摘要

Traditional debugging and disassembly tools are much demanding to analyze as well as debug Cisco IOS. At the same time, analysis with these tools isn't performed in single-step. In addition, some other defects also contribute to its inaccuracy. This paper presents a dynamic debugging platform based on a router emulator. Subsequently, a new virtualization-based method is proposed on the basis of this platform to analyze Cisco IOS. With the control on virtual hardware's running status and the trace of virtual router's running data, it's feasible to analyze IOS processes in single-step and accurately.
