Abstract

The present application provides a method and device for identifying unknown CDN nodes in CC attack protection, which relate to the field of network technology and include: receiving a hypertext transfer protocol (HTTP) request carrying a proxy field, the proxy field includes a proxy Internet protocol (IP ) address, the HTTP request includes the source IP address; if the HTTP request is sent through a browser, record the source IP address in the IP array corresponding to the proxy IP address; if the array corresponding to the proxy IP address meets the preset condition, determine the proxy IP address as The IP address of the content distribution network (CDN) node is unknown, which solves the technical problem that the CDN node is misjudged as a challenge black hole (CC) attack source and blocks the IP, causing users in some areas to be unable to access the website.

Description

Technical field [0001] The present application relates to the field of network technology, in particular, to a method and apparatus for identifying unknown CDN nodes in CC attack protection. Background technique [0002] At present, a large number of small and medium-sized websites use some content distribution networks (CONTENT Delivery Network, CDN) services to speed up website access, and will also install challenge protection software on the website server, once the user uses CDN services When the protection work is executed, the acquired agent Internet protocol (Internet Protocol, IP) is a CDN Node IP, which is a compatible CDN service, and the protection software generally has built-in popular CDN node IP addresses to achieve CDN transparency. Effect. [0003] Business and security often have compatibility problems in some scenes, the principle of the CC protection system does not open the statistics of the source IP access, once the CDN has added a service node or changed ...
