Leveraging Cyber Threat Intelligence in Smart Devices

The pervasiveness of smart devices, i.e., components equipped with feedback loops, sensing, and telecommunications for remote management, bring interesting research opportunities for incorporating contextual cybersecurity information through cyber threat intelligence (CTI). This approach enriches analysis by aggregating contextual information gathered from a myriad of unstructured data sources such as application logs, sensing data, blog posts, selected Internet-based commentary on security, vulnerability reports, and a host of other sources. The main difficulty regarding CTI is how to best integrate data into the design of protective measures. This chapter will discuss ways of leveraging CTI using a myriad of smart devices present in cyber-physical systems and internet-of-things with applications to the smart grid and smart buildings. The author will showcase the use of CTI in smart environments and how to incorporate and integrate data from multiple sources directly into the analysis efforts. The chapter will end with research perspectives and future work.
