Problems solved by technology

However, DNS over HTTP technology provides DNS domain name resolution services through HTTP protocol. The existing DNS security management system of operators cannot monitor this kind of traffic at present. There is a problem of lack of DNS over HTTP protocol supervision, which cannot meet the "Internet Domain Name Management Measures" proposed by the Ministry of Industry and Information Technology. Regulatory requirements seriously affect the information security of DNS domain name services

Abstract

The invention provides a safety supervision method for a DNS over HTTP protocol, and the method comprises the steps: inputting DNS over HTTP traffic, and collecting the traffic information through a feature identifier; analyzing the collected flow information in real time to obtain a response load, and then performing deep analysis on the response load to obtain analysis information; analyzing the association analysis information to determine an ICP service; and comparing the analysis information with preset information to judge whether the analysis information is consistent with the preset information or not, if so, reporting and displaying the analysis information, and if not, marking the analysis information as abnormal information, displaying and giving an abnormal alarm. According to the method, the DNS over HTTP traffic can be accurately analyzed, data analysis is carried out, the IP of the analysis server, the number of analysis times, the analysis address and the analysis time delay statistical information are obtained, safety service hidden dangers such as DNS over HTTP manufacturer service faults are found in time, and the problem that DNS over HTTP protocol analysis supervision is lacked is solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a safety supervision method for the DNS over HTTP protocol. Background technique [0002] DNS domain name resolution is the actual addressing method of Internet applications, a very important Internet infrastructure, and the starting point and entrance of the Internet. Various Internet-based Web services and Email services all rely on DNS. With the rapid development of the Internet and the advancement of technology, network security incidents occur frequently, and various attacks against the DNS system continue to escalate. In order to ensure the efficient and stable operation of the DNS system, the resolution service quality of the DNS system, and improve the business experience of Internet users, more and more Internet companies have begun to use DNS over HTTP technology to resolve domain names, taking advantage of the openness and customizability of the HTTP protocol , DNS ...
