摘要：Software Engineering covers the definition of processes, techniques and models suitable for its environment to guarantee quality of results. An important design artifact in any software development project is the Software Architecture. Software Architecture's important part is the set of architectural design rules. A primary goal of the architecture is to capture the architecture design decisions. An important part of these design decisions consists of architectural design rules In an MDA (Model-Driven Architecture) context, the design of the system architecture is captured in the models of the system. MDA is known to be layered approach for modeling the architectural design rules and uses design patterns to improve the quality of software system. And to include the security to the software system, security patterns are introduced that offer security at the architectural level. More over, agile software development methods are used to build secure systems. There are different methods defined in agile development as extreme programming (XP), scrum, feature driven development (FDD), test driven development (TDD), etc. Agile processing is includes the phases as agile analysis, agile design and agile testing. These phases are defined in layers of MDA to provide security at the modeling level which ensures that security at the system architecture stage will improve the requirements for that system. Agile modeled Layered Security Architectures increase the dependability of the architecture in terms of privacy requirements. We validate this with a case study of dependability of privacy of Web Services Security Architectures, which helps for secure service oriented security architecture. In this paper the major part is given to model architectural design rules using MDA so that architects and developers are responsible to automatic enforcement on the detailed design and easy to understand and use by both of them. This MDA approach is implemented in use of Agile strategy in three different phases covering three different layers to provide security to the system. With this procedure a premise conclusion has been given that with the system security the requirements for that system are improved. This paper summarizes that security is essential for every system at initial stage and upon introduction of security at middle stage must lead to the change in the system i.e., an improvement to system requirements.
