An automatic fuzz testing method designed for detecting vulnerabilities on all protocol

Nowadays more fuzz testing research mainly focuses on some certain phase and on some certain protocol, there is not an research on integrated system realization has been emerged. This paper presents the idea of an automated fuzz testing method for all protocols. First it adopted Finite State Machine (FSM) model in fuzz testing, and after a FSM constructed an efficient algorithm is presented for state space reduction. Last it selected every sequence for the mutation test. In this method, the FSM is created by program other than manual work that make the fuzz testing automated and suit for all protocols.
