Security Analysis And Optimization Of Network Information System Of Company B

With the development of the information society,communication technology has penetrated into almost all industries of daily life and has had an incredibly significant impact on people’s routine work or daily life.At the same time,the progress of communication technology has also fed back the process of social informatization.The application and popularization of the network bring convenience to people’s work and life,but only make sense by ensuring the security.Today,many companies have brought daily operation online,stored data on the Internet,and completed actions through the network.Therefore,the security of enterprise network information systems has increasingly become important.How to improve the security level of information systems is the key role in the process of enterprise informatization.This article took "Security Analysis and Optimization of Network Information System of Company B" as the research topic,analyzed the potential dangers existing in the company’s current network information system,and proposed optimization solutions to help the company solve the existing issues.Meanwhile,this paper analyzed the cutting-edge research,industrial development and technology application of information security globally,reviewed and summarizes the theory and key content of information security,and elaborated the concept,classification and strategy of network information system security.Based on the fundamental theory of network information system security,this paper evaluated the current situation of company B’s network information system from four aspects: routing / switching equipment,database,operating system,and external network connection.It combined the actual requirements of the company,and brought up the goals and design principles of system optimization.This article formulated a specific optimization plan for the company’s information system,planned a security management system,made equipment selection accordingly,and verified system functions of the actual application of the network to verify the feasibility of the optimization plan.Penetration testing was also performed on the optimized network information system of Company B through the common network attack methodology in recent years,and a solution was proposed based on the results of the penetration test to make Company B’s network information system more efficient.It is hoped that some of the research results can be appropriate references for the evolution of enterprise network information systems.
