Database security situation assessment method based on time sequence analysis

The invention discloses a database security situation assessment method based on time sequence analysis, and aims to solve the problems that the demand of a database is increasingly growing along with the development of an electronic internet, and similarly, the demand of database security also exists along with the increase of the demand of the database. The distributed database provides a high-efficiency and high-security database function for the current internet era, and the data security is unprecedentedly improved by means of data slicing and the like. According to the database security situation assessment method based on time sequence analysis, in a distributed database storage system, by collecting continuous habits of a user to access a database in a time sequence, analyzing the probability of the user to access each server, and calculating the security situation of the user to access the database, the security situation of the user to access the database is evaluated. And the high-risk security sit
