Enabling design of agile security in the IOT with MBSE

Design for system security within the IOT is a critical issue for Systems Engineering. The threat is agile and always evolving. One promising approach is the application of agile systems architecture to the design of system security. However, to be successful, systems engineers and security engineers will require a design process and framework that supports the definition of a system combining both resilience and continuous evolution of security capability. This paper presents an overview of the agile systems architecture, along with an approach to model and describe the specific elements of the agile architecture through application of model-based systems engineering and use of enterprise architecture frameworks to address features of the architecture that reside in both the design time and operating time domains.
