Research on software hazard classification

The detection and prevention of hazard is the focus of software safety. It helps safety personnel to eliminate hazard and find unknown hazard through the research on the classification of software hazard. The current situation of software hazard and concepts are first introduced in this paper. And then software hazard classification is presented from three aspects which based on the structure, system and process. This paper provides a new good way to solve software safety testing and testing requirements analysis from the angle of reuse and efficiency.
