The most important factor when identifying an organization’s risk exposure associated with IoT devices is visibility into all networked devices. This means having a comprehensive inventory of all the IoT devices connected to the organization’s network, as well as their configurations, functions, and security status. Visibility enables the organization to identify the potential threats and vulnerabilities that IoT devices pose, as well as the impact and likelihood of those risks. Visibility also helps the organization to monitor the behavior and performance of IoT devices, detect any anomalies or incidents, and respond accordingly. Without visibility, the organization may be unaware of the existence, location, or condition of some IoT devices, which could lead to undetected breaches, data loss, or operational disruptions.
