Abstract

The invention relates to the field of network information security, and aims to provide a user risk assessment and analysis method based on a multidimensional behavior model. The user risk assessment and analysis method based on the multidimensional behavior model can assess the user risk of the application program with logs. The present invention uses product logs to collect users, collects its behavior characteristics and behavior data to form sample data for each user, uses birch to obtain normal behavior clusters, and finally obtains the probability distribution of user normal behavior through a mixed Gaussian model, and then uses Bayesian linear Regression, to obtain a linear model that can accurately summarize the normal behavior of users. The invention can accurately, efficiently and intelligently carry out risk assessment on the state of online users.

Description

technical field [0001] The invention relates to the field of network information security, in particular to a user risk assessment and analysis method based on a multidimensional behavior model. Background technique [0002] In the Internet age, the Internet carries all aspects of our lives, from study to work, from life to entertainment, whether it is online shopping or online entertainment, it has brought us great convenience, but at the same time, there are many hidden network traps and unsafe factors. [0003] The weakest link in network security is user security. Internet users have weak security awareness and poor security management and control capabilities. [0004] In view of the current situation of network security, most network security products will give early warning of user risks. However, most network security products assess user risks based on a single large machine learning model. [0005] Based on a single huge machine learning model, a user model is ...
