It is necessary to develop systematic methodologies that enable evolution of such systems. This paper presents a prototype design for a synthetic system evolution environment (SEE). It outlines the purpose of the environment, describes its concept of operations, details its main functions and processes in utilizing the system architecture knowledge for systems evolution, and introduces its initial high level architecture design.In addition, it also documents the approach for developing the environment.展开更多

Also, the need for diversified services and flexible extensions of network security asks for more considerations and contribu?tions from the perspective of software engineering in the process of designing and constructing security systems. Based on the essence of the virtualization technique and the idea of software-defined networks, we in this paper propose a novel software-defi ned security architecture for systems. By abstracting the traditional security facilities and techniques, the proposed security architecture provides a new, simple, effective, and programmable framework in which security operations and security controls can be decoupled, and thereby reduces the software module sizes, decreases the intensity of software deve?lopments, and improves the security extensibility of systems.展开更多
