Presented an analysis method of networked software behavior and research approach based on process mining of behavior process model. The method uses the improved general behavior process model and adopts the concepts and method of process mining to perform the behavior mining and Petri net modeling on the monitoring and collecting log files, applied and verified the behavior reasonability to ensure the built model completeness and versatility; and then applied an open network environment applicable case to analyze and verify the complex interaction of system. Through the monitoring of system, it is effective to prevent malicious behaviors and improve the safety and reliability of system.
