Information Network Security In The Modern Manufacturing Systems

Content: Information Security problem in the network has been not only paid attention by individuals and companies of network information society increasingly, but also involved in all aspects. For building reliable and secure information networks, it is of great necessity and urgency to make research on security technology. The Security Technology, which based on IPSec, VPN and PKI, is coming to become the chiefly method implemented by corporations and enterprise.therby it impulse the researching and developing of network information security system based on such technology.This article is mainly for network informatio security system and how can it used in network manufacture system. Requirements and the researchs production of Chinese and foreign bring this article into being. The population of network user increase rapidly, therefor the require to the security of network information increased, especially to some network user, such as banks and telecom, who need full secure sysytem that just a firewall can not meet them. To resolve these problems above, This article designs a network information security system in this article. Firstly , it simply presente the key technology of future manufacturing, sercurity technology of network manufacturing and its frame. Secendly, this article give the resolve method based on the technology above, then, research the key technology of network information secure and implement them.in the end, this article get the whole network information security system to the problem of network manufacturing security.This article is grounded on IPV4, and compatible with IPV6, we researched network the concept, background and implemented protocol of sercurity. Also we analyzed the working mechanism, protocols, standards, arithmetic, and system of VPN and PKI of network security sysytem. and constructed a whole network information security system, which based on linux and freeswan, open source code, and comprised of VPN and PKI.at last, by this network information secuitiy system, we can construct a fortress defend against network attrack and information leak.
