| Network security problem increasingly serious,on the one hand,is due to the application range of the network is more and more widely,the scale is more and more big,on the other hand is due to system vulnerability appear constantly,simple easy to use the tools become more popular,make network security events emerge in endlessly.So,in order to guarantee the security of the network and information,first of all need to deploy a large number of enterprise network security equipment such as firewall,intrusion detection,anti-virus software,in order to build a secure network computing environment,guarantee the business data confidentiality,integrity,and availability of information.As power information network increasingly rich business form,the seal of the network itself and also affects the running mechanism,security challenges facing the tend to be more diversified and complicated.Considering the complexity of the electric power information between scale,and to the whole network security is more and more high demand,regular security solution is not well done the task of network security.The overall objective of network security situation assessment,is to build a unified and the integration of large-scale network security situation assessment system,provides a unified the entire network security strategy and wide-area situation assessment of technical means,to implement network security situational awareness and decision support.This research mainly realize the information network boundary equipment,network equipment and the basic information of the terminal equipment,real-time collecting information and security audit information and visual display,vulnerability scanning system,an anti-virus system and IDS system and equipment of log data real-time acquisition and warning.This paper studies a layered information network security threat assessment and prediction model,and realizes the analysis method of network security risk point and weak link. |
