Research On Safety Protection Management System Of Intranet Terminal

Nowadays,with the rapid development of network technology and information technology,the scale of network is becoming larger and larger.People's life,work,study,entertainment and communication can not be separated from the network,and it is widely used by enterprises and institutions to facilitate the internal communication of employees and improve office efficiency.The importance of network security is becoming more and more prominent.From the background and significance of Intranet Security management,this paper describes the network security problems that have appeared in the society,analyses the corresponding solutions,discusses the mechanism management,technical protection means and the application of new technologies,designs the architecture of network security,analyses the attributes and security elements of network security,and designs the system.Functional requirements,design principles,design objectives and architecture are analyzed in detail,and some key technologies and module designs applied in the system design are analyzed.From the point of system access control,log audit,security linkage technology and intrusion detection technology,the designs are described in detail.The scheme and implementation technology construct the realization characteristics of the system,internal real-time monitoring and processing,external active defense and stability.This paper synthesizes the current mainstream network security technology,takes the network security management as the main line,innovatively proceeds from the network terminal security,through identity authentication,address binding,media access control,terminal behavior control and behavior early warning,pre-judgment and other technical means to ensure terminal security,monitor terminal behavior actions,and reduce the network.Security issues arising from individual behavior of network terminals.By setting up firewalls and intrusion detection systems to detect network behavior,network security problems caused by external factors can be effectively prevented.The establishment of log auditing system,the preservation of network behavior data,the formation of a complete chain of behavior,the abnormal behavior of the system can be traced and tracked,which is of great significance to the analysis of accident causes after the accident.In this paper,the security protection management system of the designed intranet terminal is tested.The functions of access control,log audit,security linkage technology and intrusion detection technology are deployed and tested.The test data show that the system has obvious effect on the management and control of the intranet terminal.Compared with the previous system,the management time is much shorter.The improvement of accuracy and the reduction of error rate greatly promote the improvement of network management level and Intranet security,effectively solve the problem of network terminal security management and control,and simplify and clarify the complex terminal management.At the same time,there are some problems,such as large deployment scale,complex operation,honeypot and intrusion detection technology to be improved,but lack of effective protection measures for violent intrusion,and high requirements for the comprehensive quality and professional knowledge of system managers.
