Security determination method and device for network access

Abstract

The present invention belongs to the technical field of security detection. The present invention provides a method and device for network access security determination. The method includes obtaining the characteristic information of a terminal device based on the first device parameter of historical network access to generate a plurality of first non-linear Combining feature sets; obtaining second device parameters of the terminal device’s current network access through a script program on the terminal device, extracting corresponding feature information to generate a second nonlinear combined feature set; using an outlier detection algorithm of unsupervised clustering , calculating the local outlier factor of the data points of the second nonlinear combination feature set according to the clustering of the first nonlinear combination feature set, using the value of the maximum steep point of the local outlier factor as the decision threshold ; When the value of the local outlier factor of the data points of the second nonlinear combination feature set is greater than the determination threshold, determine that the network access is safe access. The method is beneficial to improving the security detection capability of the current network access of the terminal equipment.

Description

technical field [0001] The present invention relates to the technical field of security detection, and in particular, the present invention relates to a security determination method and device for network access. Background technique [0002] With the wide application of network technology, network security has also received attention. One of the manifestations of network security is that website security is vulnerable to threats. At present, one of the main means of threatening website security is to access websites through web crawlers, so that websites cannot correctly identify normal network access. In response to this problem, the current method is to determine whether the network access is safe by collecting the operation data of the click and drag tracks generated by the terminal device in the network access. However, this method cannot completely and accurately identify secure network access, and it is easy to identify secure network access as non-secure network a...
