Internet of Things Security Risk Traceability Method Based on Improved Blocking Discrimination Algorithm
There are security loopholes in the operating system of intelligent terminal devices in the Internet of Things,built-in Web applications and databases,etc.,but there are fewer types of traceable security risks and more missed tests.Therefore,a traceability method for security risks of the Internet of Things based on improved blocking discrimination algorithm is designed.Based on the traffic collection technology and big data technology,the data collection platform of the Internet of Things inter-face is designed by composing real-time monitoring module,data interception uplink module and offline trusted platform mod-ule,and the in-depth protocol analysis of the application program interface is carried out.Based on the improved blocking dis-crimination algorithm,an analysis model of the usability risk of the Internet of Things application programming interface(API)interface is constructed,and the usability risk of the API interface is analyzed.An API interface data flow security risk tracea-bility platform is built to complete the Internet of Things security risk traceability.The experimental results show that the traceability accuracy of the proposed method can reach over 91%.
