Design And Implementation Of Internet Of Things Security Audit Management System

With the continuous updating and development of IoT technology,the impact of IoT security issues on the IoT industry is becoming increasingly prominent.Therefore,how to effectively use existing security technologies to manage and control the IoT network environment and to perceive the IoT security situation has become the current development of the Internet of Things A top priority.This paper proposes an IoT security audit management system based on log collection and processing.On the basis of not affecting the original business of the Internet of Things,it combines the complicated types of IoT devices and complex and diverse protocols,but the connection relationship of single devices is relatively single and the protocol Relatively simple and fixed,detailed analysis of the alarm characteristics of the IoT device,and targeted collection and processing of IoT security logs.At the same time,based on the analysis of the log data,it summarizes the classification of security events that occur in the Internet of Things environment.Finally,the basic security situation of the system and equipment is displayed to allow users to grasp the overall security situation of the network,realize the visualization of the security situation,and achieve the purpose of security situation awareness of the Internet of Things.The work content of the thesis is as follows:firstly,by referring to the relevant data,the significance of the system design and implementation and the research and application of related technologies are analyzed,and the design goals of the system in this paper are summarized;secondly,the application methods and implementation principles of the key technologies used to implement the system are carried out Researched and proposed the design ideas of the system;then focused on the relevant methods of obtaining environmental information of the Internet of Things,proposed the log data detection method used by the system,and classified the data and summarized a series of security event classifications,in order to Provide situational awareness information for the foundation;finally analyze and design the system application process and data flow,determine the module implementation plan,perform functional analysis,detailed design and code implementation of the major functional modules of the system,and perform functional and non-functional testing.Through the design,implementation and deployment testing of the system,it proves that the system can collect,analyze and process the security log data for the diverse IoT network environment,and through the visual display of the analysis content,the purpose of security audit and situation awareness of the Internet of Things are realized.
