Problems solved by technology

At present, there is still no fast and accurate general method for judging whether a website uses CDN technology for content distribution and site protection. Most of the existing detection technologies rely on a large number of IP address databases, which are neither universal nor suitable for large-scale testing, but also lack of timeliness

Embodiment Construction

[0022] like figure 1 As shown, this embodiment relates to a lightweight CDN node rapid detection system, including: collecting domain name information to be detected, storing the collected domain name addresses in a domain name database, and establishing a corresponding table entry The URL domain name collection subsystem is used to detect whether the direct response IP address of the domain name to be tested belongs to the acceleration node of the CDN, and can accurately classify and judge a single IP address by calling the test interface (API) provided by the CDN manufacturer DNS record. The matching subsystem is used to obtain the CNAME record of the domain name to be tested, and then matches with the common CNAME of CDN. When the conditions are met, it is directly considered that the domain name to be tested uses CDN technology. The record query matching subsystem, including a plurality of geographically separated detection nodes, is used to preliminarily determine whether...

Abstract

A lightweight CDN node rapid detection system, including: URL domain name collection subsystem, CDN vendor DNS record matching subsystem, CNAME record query matching subsystem, distributed DNS record detection subsystem, distributed active detection and matching subsystem , ANYCAST node detection subsystem, application layer response detection subsystem and domain name redirection detection subsystem, the present invention can quickly and accurately analyze and detect target sites or site groups, and determine target sites without relying on a large number of databases. Whether the site uses CDN technology to help website maintainers or security auditors evaluate the security status of the website.

Description

technical field [0001] The invention relates to a technology in the field of computer networks, in particular to a lightweight CDN node rapid detection system and method. Background technique [0002] A Content Delivery Network (CDN for short) is a distributed network established and covered on a bearer network and composed of server groups of edge nodes distributed in different regions. At present, there is still no fast and accurate general method to determine whether a website uses CDN technology for content distribution and site protection. Most of the existing detection technologies rely on a large number of IP address databases, which are neither universal nor suitable for large-scale testing, but also lack timeliness. SUMMARY OF THE INVENTION [0003] Aiming at the above shortcomings of the prior art, the present invention proposes a lightweight CDN node rapid detection system and method, which can quickly and accurately analyze and detect a target site or site gro...
