Processes in securing open architecture software systems

Abstract

Our goal is to identify and understand issues that arise in the development and evolution processes for securing open architecture (OA) software systems. OA software systems are those developed with a mix of closed source and open source software components that are configured via an explicit system architectural specification. Such a specification may serve as a reference model or product line model for a family of concurrently sustained OA system versions/variants. We employ a case study focusing on an OA software system whose security must be continually sustained throughout its ongoing development and evolution. We limit our focus to software processes surrounding the architectural design, continuous integration, release deployment, and evolution found in the OA system case study. We also focus on the role automated tools, software development support mechanisms, and development practices play in facilitating or constraining these processes through the case study. Our purpose is to identify issues that impinge on modeling (specification) and integration of these processes, and how automated tools mediate these processes, as emerging research problems areas for the software process research community. Finally, our study is informed by related research found in the prescriptive versus descriptive practice of these processes and tool usage in studies of conventional and open source software development projects.
