Design And Implementation Of Accessibility Analysis And Early Warning System For Suspicious Sites

In recent years,there are a large number of suspicious sites in the Internet environment,such as illegal political speech,phishing,gambling,pornography and obscenity,which seriously endanger people's private property security and physical and mental health,and even have a serious impact on social stability and security.Although the Ministry of public security and other network security departments have been cracking down on and administering suspicious sites,they can not avoid the circulation of suspicious sites in the network environment again,resulting in users can continue to access illegal content,thus continuing to pose a threat to Internet security.Therefore,it is very important to study and analyze the accessibility of suspicious sites in the network environment.Based on the principle of web communication between clients and suspicious sites,this paper carries out the detection and analysis of the accessibility of suspicious sites in the network environment of our country and within the scope of governance,designs and implements the accessibility analysis and early warning system of suspicious sites with data detection and acquisition module,accessibility evaluation module of suspicious sites,and accessibility display and early warning module of stations The monitoring and analysis of a large number of suspicious sites at different network levels in real time are provided to provide data and technical reference for further governance of suspicious sites.Firstly,this paper introduces the research status and analysis of suspicious site detection and identification,distributed detection and scanning,and risk assessment.In addition,it introduces the knowledge of web communication,network scanning,message middleware and risk assessment.Secondly,this paper designs and implements a suspicious site accessibility analysis and early warning system.Among them,the data detection and acquisition module mainly includes the detection and acquisition of network access data based on distributed suspicious sites,including the acquisition of DNS resolution records of suspicious site domain names,the detection of site effective IP connectivity,the detection of site web service port open status and the acquisition of site web page content.The accessibility assessment module of suspicious sites includes the establishment of an assessment index system reflecting the accessibility of suspicious sites,the establishment of an assessment model for the accessibility risk of suspicious sites,and the realization of real-time risk assessment index quantification and accessibility risk calculation based on site network access data.The accessibility display and early warning module of suspicious site includes display module and early warning module.After the user logs in the system,he can reflect the analysis content about the accessibility of the suspicious site to the system user,and give early warning feedback to the system user for the relevant information of the suspicious site that meets the early warning rules.In the end of this paper,we test the function and performance of the suspicious site accessibility analysis and early warning system,and test and display the main modules of the system from these two aspects.In conclusion,this paper completed the accessibility analysis and early warning system of suspicious sites.The test results of the system in this paper can prove that the accessibility analysis and early warning system of suspicious sites in this paper meet the design objectives of this paper.
