IoT devices represent a wide variety of non-traditional devices that are increasingly implemented in organizations due to the numerous benefits. These unique devices often pose a security challenge due to the limited size and lack of innate security making them difficult to secure with traditional security controls and methodologies. It is a combination of these factors that has rendered many devices vulnerable to attacks like the Mirai botnet. The IoT Working Group's mission is dedicated to understanding relevant use cases for IoT deployments and defining actionable guidance for security practitioners to secure their IoT ecosystem. This includes outlining best practices for securing IoT implementations, identifying gaps in standards coverage for IoT security, and identifying threats to IoT devices and implementations.
