Abstract

The present invention provides an attack identification method and its identification system, comprising the following steps: S1: Obtain an access log flow of a domain name, based on the browsing path information of each user when accessing the domain name based on the access log flow, and based on the Browsing path information determines the browsing path law of the domain name; S2: calculates the probability of each user using a browsing path in the browsing path law when accessing the domain name according to the browsing path law; S3: obtains when a user visits the domain name The number of times the browsing path is taken; S4: Based on the number of times and the probability, determine the threat level of the user using the browsing path to access the domain name.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an attack identification method based on path context information and an identification system thereof. Background technique [0002] At present, mainstream network security algorithms use statistics and regular matching methods, such as statistics of IP-based pv information, ua information, packet size information, regular-based waf algorithm, etc., and then according to the corresponding variables in a certain time window The difference between the statistical information and the benchmark value is used to judge whether the visit is legitimate. The existing statistical methods mainly have the following shortcomings: [0003] 1. It is easy to lose context information and key features of threat identification; [0004] 2. It is greatly affected by the interference of noise, and the accuracy of the algorithm will be seriously affected in extreme or unexpected situations...
