| Abstract: | Cisco IOS processes can not be dynamically analyzed,and it is difficult to intercept system abnormalities of communication process. A method based on virtualaization is proposed to analyze Cisco IOS communication process.Hardware abstraction layer virtual machine is constructed,and a dynamic analysis platform based on virtualization is designed for IOS.This paper introduces methods for extracting key instruction stream and communication features.The multiple instruction set architecture and multiple versions of Cisco IOS is proved.Experimental results show that this method can effectively intercept the designated communication process. |

| Keywords: | virtualization dynamic analysis communication process key instruction stream finite automata |
