Research And Design Of Enterprise Network Security System In The Age Of Industry 4.0

In the 21 st century,with the rapid development of the global economy,information technology has also developed rapidly.The application of computer networks and the Internet has penetrated into all areas of society.Network information has brought tremendous economic benefits and unexpected convenience to enterprises,but at the same time,it also brings hidden network security issues and restricts the development of enterprises.Although many companies have already established their own network security system,with the advent of the Industry 4.0 era,companies are moving in the direction of intelligence.Existing network security systems can no longer meet the needs of enterprises and users,and there are some security risks.Under this background,it is very necessary to build a new type of network security system in the era of Industry 4.0.This paper mainly analyzes the current situation of domestic enterprise networks.Combining the current situation of a certain enterprise's network,the paper analyzes the problems and hidden dangers of current enterprise network security.From the enterprise itself,specific solutions are given according to the deep research and analysis of security technology means,network domain protection,enterprise security management,cloud platform construction and other aspects.and finally built a comprehensive network security protection system of physical protection + cloud platform protection.The basic technologies involved are firewall,anti-virus software,file encryption and digital signature technology,access control technology,intrusion detection technology and identity authentication;and the enterprise network is divided into four areas,sub-domain boundary security domain,data center domain,security management domain and access security domain.Different areas adopt different means for security protection,and establish a unified intelligent security operation management center to control global attack events.In addition to technical protection,it also strengthens the network security management of enterprises.After the security system is deployed and upgraded,the analysis of the operation results after a period of time shows that the security system can meet the basic requirements of information security level protection,which can effectively prevent attacks and threats from all aspects,and has strong robustness.
