The need for advanced cyber security measures and strategies is attributed to modern sophistication of cyber-attacks and intense media attention when attacks and breaches occur. In May 2014, a congressional report suggested that Americans used approximately 500 million Internet-capable devices at home, including, but not limited to Smartphones, tablets, and other Internet-connected devices, which run various unimpeded applications. Owing to this high level of connectivity, our home environment is not immune to the cyber-attack paradigm; rather, the home has evolved to become one of the most influenced markets where the Internet of Things has had extensive surfaces, vectors for attacks, and unanswered security concerns. Thus, the aim of the present research was to investigate behavioral heuristics of the Internet of Things by adopting an exploratory multiple case study approach. A controlled Internet of Things ecosystem was constructed consisting of real-life data observed during a typical life cycle of initial configuration and average use. The information obtained during the course of this study involved the systematic acquisition and analysis of Smart Home ecosystem link-layer protocol data units (PDUs). The methodology employed during this study involved a recursive multiple case study evaluation of the Smart Home ecosystem data-link layer PDUs and aligned the case studies to the existing Intrusion Kill Chain design model. The proposed solution emerging from the case studies builds the appropriate data collection template while concurrently developing a Security as a Service (SECaaS) capability to evaluate collected results
