Research on Firmware Vulnerability Mining Model of Power Internet of Things

Power IoT (Internet of Things) has been developing for a few years where various types of terminals are deployed. Since the power IoT devices need to be connected to the public network, the security situation is more severe, and it is imperative to develop an efficient and reliable vulnerability mining model for the device firmware in the power IoT field. Based on this, this paper analyzes the common mining means of power IoT device firmware vulnerabilities including static and dynamic analysis methods. By comparing the characteristics of different mining techniques and their applicability, an IoT device firmware vulnerability mining model applicable to the power system environment is proposed and its process and associated methods are designed. Finally, a test system is established to verify the effectiveness of the proposed model compared to the common static and dynamic analysis tools. The test results show that the proposed model demonstrates better performance in terms of execution time and code coverage efficiency.
