Problems solved by technology

[0002] In the current network access, one of the main means of threatening the security of the website is to access the website through web crawlers, which makes the website unable to make correct judgments, and thus easily leads to wrong responses.
To solve this problem, the current method is to collect data such as click time and mouse dragging trajectory during the user verification process, and identify the type of user based on this behavior data. This method has a high error rate, and it is easy to identify real users as abnormal users. low accuracy

Abstract

The present invention belongs to the technical field of security detection. The present invention provides a method and device for determining abnormality of terminal equipment network access. Eigenvalues, and form a nonlinear combination feature set; calculate the average value of all corresponding eigenvalues ​​within a set time period for the eigenvalues ​​of the nonlinear combination feature set, and calculate the eigenvalue of the terminal device Chi-square statistic; when the corresponding feature value is an outlier obtained by using the chi-square statistic, it is determined that the corresponding network access is an abnormal access. The method is beneficial to improve the judgment ability of the terminal device to judge the abnormality of the current terminal device network access.

Description

technical field [0001] The present invention relates to the technical field of security detection, and in particular, the present invention relates to a method and device for determining abnormalities in network access of terminal equipment. Background technique [0002] In the current network access, one of the main means of threatening the security of the website is to access the website through web crawlers, which makes the website unable to make correct judgments, and thus easily leads to wrong responses. To solve this problem, the current method is to collect data such as click time and mouse dragging trajectory during the user verification process, and identify the type of user based on this behavior data. This method has a high error rate, and it is easy to identify real users as abnormal users. The accuracy is low. Contents of the invention [0003] In order to overcome the above technical problems, especially the problem in the prior art that when logging into th...
