Abstract

The invention relates to a quick positioning processing method and system for a malicious domain name request terminal. The method comprises the following steps: S1, establishing a database on a DNS server; S2, acquiring a DNS server log, and extracting a domain name of the DNS server log; S3, if the current domain name is in the white list database, entering the step S6, otherwise, entering the step S4; s4, if the current domain name is in the blacklist database, locating an infected terminal IP corresponding to the domain name, and giving an alarm, otherwise, entering the step S5; s5, if itis judged that the current domain name is a benign domain name, adding the domain name into a white list database, and entering S6; if it is judged that the current domain name is a malicious domain name, adding the domain name into a blacklist database, positioning an infected terminal IP corresponding to the domain name and host user information of the infected terminal IP, and giving an alarm;and S6, deleting the DNS server log. According to the invention, the host IP address accessing the malicious domain name and the host user information thereof can be quickly and accurately positioned.

Description

technical field [0001] The invention relates to the technical field of computer desktop terminal system security, in particular to a method and system for quickly locating and handling a terminal requesting a malicious domain name. Background technique [0002] With the continuous growth of global Internet users and the enrichment of network applications, the technology that threatens network security is also developing continuously. The threats to property safety and privacy security brought by malicious domain name websites to netizens are also increasing rapidly. Increased the cost of network security protection construction. Especially for some large enterprises, the number of desktop terminals is huge. Once the host is infected, because they are in the same local area network, the hosts can be related to each other, and the data can be called at any time. Malicious code will quickly spread among multiple hosts. Infect. [0003] However, it is difficult for existing te...
