Over the past three decades software engineering researchers have produced a wide range of techniques and tools for understanding the architectures of large, complex systems. However, these have tended to be one-off research projects, and their idiosyncratic natures have hampered research collaboration, extension and combination of the tools, and technology transfer. The area of software architecture is rich with disjoint research and development infrastructures, and datasets that are either proprietary or captured in proprietary formats. This paper describes a concerted effort to reverse these trends. We have designed and implemented a flexible and extensible infrastructure (SAIN) with the goal of sharing, replicating, and advancing software architecture research. We have demonstrated that SAIN is capable of incorporating the constituent tools extracted from three independently developed, large, long-lived software architecture research environments. We discuss SAIN’s ambitious goals, the challenges we have faced in achieving those goals, the key decisions made in SAIN’s design and implementation, the lessons learned from our experience to date, and our ongoing and future work. 

Analyzing, implementing and maintaining security requirements of software-intensive systems and achieving truly secure software requires planning for security from ground up, and continuously assuring that security is maintained across the software's lifecycle and even after deployment when software evolves. Given the increasing complexity of software systems, new application domains, dynamic and often critical operating conditions, the distributed nature of many software systems, and fast moving markets which put pressure on software vendors, building secure systems from ground up becomes even more challenging. Security-related issues have previously been targeted in software engineering sub-communities and venues. In the second edition of the International Workshop on Security from Design to Deployment (SEAD) at the International Conference on Automated Software Engineering (ASE) 2020, we aimed to bring the research and practitioner communities of requirements engineers, security experts, architects, developers, and testers together to identify foundations, and challenges, and to formulate solutions related to automating the analysis, design, implementation, testing, and maintenance of secure software systems.
