Abstract: This paper proposed a new method aiming at integrating the safety analysis in software design and development. Model Driven Architecture is used for the basic framework. By making use of UML extension, UMLsec modeled the Platform Independent Model of software security,which achieved more security requirements in the initial stage of the system design cycle. hhis approach reduces the risk and the cost of software development and improves the reusability.
