Research On IPTV Network Security Test And Intelligent Evaluation Method

With the development and popularization of Internet technology,IPTV has emerged as a brand-new technology integrating communications,Internet,multimedia and other technologies,and has made outstanding contributions to the promotion of the development of my country's intelligent terminal TV industry.However,the IPTV service bearer network uses the IP network as the basic bearer network and is directly interconnected with networks such as the Internet,so it faces various network security risks that the IP network has.However,the IPTV network penetration test and security assessment lack the corresponding technical theoretical support.The current attack graph model has a single quantitative index,poor objectivity,and slow generation efficiency.The pathfinding algorithm for the target node lacks the improvement of the corresponding index,resulting in generation The penetration attack path effect is poor.In addition,the penetration testing tools on the market have many problems such as high learning costs,low visualization,and difficult management of penetration results.This dissertation focuses on the above-mentioned problems,and the main work includes the following aspects:First of all,we analyze the one-sided problem with the traditional attack graph model.This article starts with the attribute attack graph and uses the CVSS indicator to quantify the vulnerability of IPTV network nodes from the perspective of attack success rate,attack revenue,and attack cost.In order to facilitate the implementation of the subsequent attack path generation algorithm,the attribute attack graph is improved so that the pre-attribute nodes of the same attack node satisfy the "or" relationship.Then in order to fit the quantitative index of improving the attribute attack graph,the ant colony algorithm is used to generate the attack path.In addition,relevant improvements are made to the heuristic factor,heuristic function,and pheromone update function of the ant colony algorithm,so as to improve the generation efficiency of the penetration attack path and reduce the length of the generation path.Use the results of the penetration attack path calculation to conduct a security assessment of the IPTV network,and simulate the IPTV network system for algorithm testing and performance verification.Finally,based on the Metasploit penetration testing framework,using Spring Boot technology combined with the above theoretical foundation,a set of IPTV network security testing and intelligent evaluation platform is realized.The platform has seven modules: user management,intelligence collection,vulnerability detection,attack graph generation,penetration attack,post-penetration attack,and report generation.And the platform has the characteristics of high maintainability,strong scalability,convenient management,and friendly interface.
