IoT is one of the biggest new developments in IT, with growth expected to reach billions of devices in the short term. There is, however, a major gap in understanding of security for IoT. Many first-wave IoT systems are showing significant security weaknesses, and security is often recognized as one of the key blockers to successful IoT deployments. In this course, Malcolm Shore provides guidance for businesses intending to deploy IoT solutions on the end-to-end security architecture required to ensure the comprehensive security of their deployment. He provides an introduction to security architecture and discusses emerging IoT reference architecture, domain specific architecture, proximity network services, and more.
