Design And Implementation Of Key Technologies In Integrated Network Security Management System

With the rapid development of information technology,computer networks play an increasingly important role in the current society.However,the security problems that accompany them are also increasing day by day.Such as hacking and viruses have brought great harm to the network.Therefore,how to effectively guarantee the reliability and security of the network has become an urgent problem to be solved.Although there are many ways to solve network attacks,these solutions are aimed at a specific security problem and it is difficult to deal with the various network attacks that are currently responsible.Therefore,in order to deal with various security issues more comprehensively,building an integrated network security system has certain practical value.The integrated network security management system can make full use of the advantages of various network security tools,eliminate a large number of false positives and false negatives,and conduct multi-dimensional and multi-level defense of the network.Based on the research on the existing network security technologies,the paper builds an integrated network security management system and designs and implements key technologies.First of all,in the data acquisition module,the data generated by multiple safety devices have heterogeneous characteristics,and a data standardization scheme is designed;for the time-saving characteristics of different safety devices,the passive acquisition and active acquisition are designed.The scheme improves the collection efficiency.For the heterogeneous and time-varying characteristics of network devices,plug-in dynamic loading is used to improve system scalability.Secondly,for the core function of the system-association engine,the paper designs an association algorithm combining event sequence correlation and heuristic correlation,which can not only detect known network attacks,but also provide early warning of unknown anomalies,and can effectively reduce false alarms.,missing report.Moreover,XML is used to construct association rules and detailed analysis is performed on event association processes.Then,a testenvironment is set up to test the correlation engine and the effectiveness of the association engine is verified.Finally,the system was deployed and implemented in the computing center,and the various functional modules of the system were verified to ensure the effectiveness of the system.The integrated network security management system integrates multiple network security tools to build a security platform that integrates multiple functions such as asset management,vulnerability scanning,intrusion detection,and risk assessment,so that the network management becomes more comprehensive and efficient.Convenient.
