Embodiment

[0020] The present invention provides a method for tracing the source of a malicious domain name infected host, the method comprising:

[0021] Establish a platform, including acquisition server and big data analysis platform and establish a database,

[0022] The establishment of the database includes: collecting DNS server logs, anti-virus killing logs, virus access URL characteristic information, disposal knowledge base, and IP address division information of each associated host in the power grid system on the platform, and according to the collected virus access URL characteristic information Establish a virus signature table, establish a processing suggestion table according to the disposal knowledge base, and store IP address division information;

[0023] Obtain the DNS server logs from the accessed host through the collection server, use client access as the trigger condition, analyze and normalize the DNS server logs through comparative analysis, and then compare the...

Abstract

The invention belongs to the field of power system computers. The method is a malicious domain name infected host tracing method. The method comprises: establishing a database on a platform, collecting DNS server logs, anti-virus searching and killing logs, virus access URL feature information, a disposal knowledge base and IP address division information of all associated hosts in a power grid system on a platform; establishing a virus feature table according to the collected virus access URL feature information, establishing a processing suggestion table according to a processing knowledge base, and storing IP address division information; and obtaining a DNS server log from a host, analyzing and normalizing the DNS server log through comparative analysis, then performing feature comparison with the virus feature table, generating an alarm according to suggestions corresponding to virus features compared in the virus feature table in the processing suggestion table, and then enteringa processing flow. According to the invention, the attacked host is disposed in time according to the disposal suggestions, thereby achieving the purposes of ensuring the security of the informationintranet and reducing the security threat.

Description

technical field [0001] The invention relates to the field of power system computer software, and specifically relates to a method for tracing the source of hosts infected by malicious domain names. Background technique [0002] For the power system, the data is huge. Once the host is infected, due to the correlation of multiple hosts, the call of data at any time will quickly infect among multiple hosts. To monitor the domain name resolution function of the DNS server of the system, it is necessary to quickly locate the IP address of the host accessing the malicious domain name and the unit to which the host belongs, so that each unit can quickly locate the infected host, achieve rapid warning and timely disposal, and improve protection ability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for tracing the origin of hosts infected by malicious domain names, which is used to solve the problems of slow ...
