Study On The Security Technology Of Multistage Multi-domain NMS Synergy And NMS Password

With the continuous development of society informationization, the network scale isbecoming bigger and bigger, together with the heterogeneity more strong, and the hierarchicalregion more diversified, the requirement of network management needs to be on a high level,so a variety of network management system appeared. Therefore, security problems appear.Administrator password security control as the core elements of network management system,to strengthen the security of network management efficiency is very important.This paper has analysised for the current situation of the multistage multi-domainnetwork management and the security problems, and propose solutions to some problemssuch as the current admin password management chaos, lack of collaborative, and designs themultistage multi-domain network collaborative management system, and designs and realizesthe dynamic password management system.Based on the network management technology and identity authentication technology,this paper studies multistage multi-domain network management based.And designed thenetwork collaborative application model for The current network system, to realize the set ofnetwork management system of the collaborative applications. Thus, designed the model ofsecurity network management combining with the SNMPv3security mechanism, CA securityservice system based on the collaborative management model. At the same time, using thesecurity network management model, intermediate control server removes the adminpassword to intermediate control server for unified management, network managementpassword of the dynamic, transparent application deployment, and the network interactivedata encryption, authentication etc.Based on the above research, this paper designed the multi-stage multi-domain networkmanagement coordination system, and design the dynamic password management system.The dynamic password management system uses the MVC layered design ideas, follows themodule hierarchical design principles of high cohesion and low coupling, it has goodscalability.
