Problems solved by technology

In view of this camouflage, although the current existing technology is already protecting by matching the characteristics of the access behavior of the requested IP, such methods are often used for a long time after specifying the rules at one time, and do not update the rules during the period. , so the ever-changing CC attacks cannot be identified and protected immediately

Abstract

The invention relates to a method and an apparatus for recognizing CC (Challenge Collapsar) attacks based on log analysis. The method for recognizing CC attacks based on log analysis comprises the steps of obtaining IP (Internet Protocol) request information in logs, comprehensively analyzing the IP request information based on a list and an attack characteristic library and outputting an analysis result, and carrying out recognition based on the analysis result, namely recognizing IP requests as normal requests and releasing the IP requests if the analysis result is normal, and otherwise, recognizing the IP requests as the CC attacks, and adding source IPs in the IP request information to a blacklist, intercepting requests from the source IPs and automatically extracting characteristics from the IP request information and adding the characteristics to the attack characteristic library.

Description

technical field [0001] The present invention generally relates to computer network security, in particular to a log analysis-based CC attack identification method. Background technique [0002] In recent years, with the rapid development of the Internet, various network applications and network attacks are also increasing, which makes the network environment more complicated. Moreover, the variety of network architectures and applications that provide customers with an improved experience is increasing, which is convenient for cyber attackers as well as customers. Among them, the development of CDN (full name is Content Delivery Network, that is, content distribution network) is gradually accelerating. The basic idea of ​​CDN is to avoid as far as possible the bottlenecks and links on the Internet that may affect the speed and stability of data transmission, so as to make content transmission faster and more stable. By placing a layer of intelligent virtual network based o...
