New Security State Awareness Model for IoT Devices With Edge Intelligence

Edge computing has become one of the most critical technologies in the Internet of Things (IoT), which is vulnerable to be hacked itself due to its closing to the terminals' wide variety of applications and digital assets. Aiming to find a new paradigm for cybersecurity based on edge computing at the device level, we leverage the storage, communication, and computational capabilities of edge computing devices to acquire and transform the massive amounts of data generated during work into the states. Through the analysis of the states, the security threats of the edge computing device can be identified. Based on the complex network theory, a security state awareness model is established, which can accurately indicate a device's current security state, be aware of the attack behavior, and perform protection methods.
