Modeling and Architecture Design for Continuous Assurance Testing (MADCAT)

Internet of Things (IoT) devices are now ubiquitous in today's world. According to IoT Analytics, it is likely that 27 billion IoT devices will be in operation by 2025. The types and capabilities of these devices vary wildly, and with their level of penetration into many aspects of today's world, the ability to test and secure these devices is essential and growing exponentially. There is a clear need to be able to perform thorough, automated testing on IoT devices to ensure they are both safe and secure not only when they are in development but periodically as new vulnerabilities are discovered and new updates are created and deployed. Tangram proposes a component-based software engineering (CBSE) system that uses a test orchestration engine and a variety of focused test components to meet the needs of automated testing for a large number of IoT and even other software-based systems. This CBSE system will be highly scalable to meet future needs and will be able to be hosted in containers for portability and flexible deployment. Tangram's message set generation capabilities allows for easily creating components that can talk to these devices effectively, which is a crucial capability. That along with built-in run-time assurance (RTA) features and other existing capabilities means Tangram is very well suited to help the government and commercial entities secure their IoT resources.
