A research of Critical Information Systems Security Based on Diskless-network
X Departments · 2011
Some government departments and enterprises have great important and sensitive information,which completely physical isolation with the Internet.The information will not receive attraction from Internet,for it is more important than the most important data which can be touched through external network.At present,this type of application mostly achieved by the establishment of private network,which has its commonly security risks: improper operating from the users,operating experience comes to slower and slower,hazards and damages from Trojan horses and viruses,vandalism from unauthorized user by accident,disclosure in a way of intentional or unintentional by external maintenance staff......It is not an appropriate thing that the safety relay on the quality of users rather than management and technology.This article established a safe network model for important information from the way of network environment and data encryption.This model had been put into practice for some time,proved it's highly safety,strong reliability,easily expandability properties,a low cost and little need to maintenance system.Even if the worst case occurs,leaks can also be controlled in the range of minimal.In all,it is a high value security network model.
