Design And Research Of Hacker Intrusion Database Detection System

Computer and network technology in contemporary society is in a trend of rapid development,with the rapid development of computer network technology,database technology is currently in all walks of life has been widely used,but out of the requirements for interconnection applications,in addition to sensitive industries have special on request,almost all databases are connected to the internet.Therefore,the database security issues should not be underestimated,increasing the degree of database security for the protection of the internal database data security plays an important role.Combined with UML modeling technology,this paper designed a database security testing system and tested the system.First of all,this article analyzes some mainstream database security requirements and the significance of studying the database security,and introduces the hacker prevention technology about the database security.The main functions of hacker intrusion detection system are proposed,including data acquisition,rule base module analysis,rule base analysis,preprocessing and detection analysis.The purpose of these functions is to prevent misoperation,external attack and internal attack System hazards,and in the above-mentioned attacks on the system before the system can respond to and intercept.Secondly,combined with the needs analysis,the UML modeling technology is used to construct the class diagram and flow chart.In the detection and analysis module,the data mining technology is applied to realize the scientific and efficient rule mining.By analyzing the characteristics of data security and hacker attack network security detection technology,a hacker attack network security detection system is designed according to the proposed scheme.In the system,in order to improve the security of the database,a new method of pattern creation and identification for SQL is proposed.In the system design scheme,the author proposes that the SQL statements should be separated from the three dimensions of sentence structure,data manipulation and system behavior a comprehensive test.Through more accurate semantic analysis,it can judge the user's behavior promptly and efficiently,which makes the detection scope wider and the detection accuracy higher.Finally,this paper builds the environment and realizes the function of the hacker detection system.According to the method of system testing,the paper tests the reliability and functionality of the intrusion detection respectively.The test results show that the system can achieve the expected set the effect.At the end of the article,the paper summarizes the research work of the dissertation,points out the innovation points and advantages of the dissertation,and analyzes the direction and content of further research.
