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 invention belongs to the technical field of security detection, and provides an abnormity judgment method and device for terminal device network access, and the method comprises the steps: responding to a network access request sent by a terminal device, obtaining a plurality of nonlinear feature values of the terminal device through a script, and forming a nonlinear combination feature set; solving an average value of all corresponding characteristic values in a set time period for the characteristic values of the nonlinear combination characteristic set, and calculating a chi-square statistic of the characteristic values of the terminal device; and when the corresponding characteristic value obtained by utilizing the chi-square statistics is an outlier, judging that the correspondingnetwork access is abnormal access. The method is beneficial for improving the judgment capability of judging the abnormal access of the current network access of the terminal device.

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...
