Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] In order to solve the time-consuming and labor-intensive problems caused by manually using third-party tools for packet capture analysis in the prior art when there is a need for DNS attention, and the problem that historical data cannot be reproduced, the embodiment of the present invention provides a DNS-based response The recursive log extraction method of data packets is used to easily and quickly mine and utilize DNS data packets effec...

Abstract

The invention provides a recursive log extraction method and device based on a DNS response data message. The method comprises the steps: acquiring the DNS response data message; analyzing and extracting values of fields in the DNS response data message; recording the values of the fields into a recursive record in a first separator interval form according to the fields; aggregating the recursion records at a second separator interval to form a DNS recursion log. Compared with the prior art that a third-party tool is manually used for capturing packets, the method provided by the invention has the advantages that operations such as field value extraction, recursion record formation by the first separator interval and DNS recursion log formation by the second separator interval are carried out on the DNS data message, and therefore the DNS recursion log which is generated in real time and is uniform and clear in format is obtained; the DNS data message can be simply, conveniently and effectively mined and utilized, and historical data is reproduced.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a recursive log extraction method and device based on DNS response data messages. Background technique [0002] In the existing technology, when there is a demand for DNS attention, most rely on manual use of third-party tools to capture packets, which is not only time-consuming and labor-intensive, but also cannot reproduce historical data, and DNS data message information has not been effectively mined and utilized . Contents of the invention [0003] The embodiment of the present invention provides a recursive log extraction method based on the DNS response data message, which is used to easily and quickly dig and utilize the DNS data message effectively and reproduce historical data. The method includes: [0004] Obtain DNS response data message; [0005] Analyzing and extracting the value of the field in the DNS response data message; [0006] Record the v...
