Improved vulnerability testing mode based on syntax analysis and regular expressions test cases generation

Protocol testing has become the most vital part in the protocol engineering. Before protocol is deployed to Internet or communication network, all kinds of testing must be done with adequate test cases, while robustness testing is one of them. In this paper, we presented an integrate system for vulnerability testing with some improved techniques, such as extended Petri net, automatic test cases generation based on regular expression, syntax analysis method and so on. Finally, we implemented the testing system to Apache HTTP server 2.2 to evaluate its protocol robustness and vulnerability tolerance, and thereby verify our testing mode.
