Research On Network Scrutiny And Fire-proofing Technology

The title of this thesis is "Research on the net security and fire-proofing technology". The title includes two key words "net security" and "fireproof technology". Why is it so entitled?First, because we are living in a net world now, which is symbolized by electronic business. Our life is related to the net, we can't live without it. For example, Email, electronic business, acquiring all kinds of information etc. So it is without saying that the net security is very important. We can't imagine how to survive in an unsafe net world. How to convey the information completely, validly and legally? So we'll talk about the topic of the net security. Of course, net security is a big topic, which includes: the definition of the net security, the identification of the ideal safe net, different understanding of the net security, proving the net security and the measures of protecting the net security etc.Second, why to mention fireproof technology while talking the net security? That' s because when we talk about net security we'll naturally think about net security technology; and fireproof technology is one of the valid measures of ensuring the net security. So it is worth researching.After studying many relative books and combining with my own understanding, I write this thesis.This thesis includes: the meaning & characteristics of network security; threatening & attacking that the computer network faces; general measures to protect network security; brief introduction, classification and relationships to network security technology; general description and key technology of fire proofing (Package filtrate technology, delegating technology, NAT technology); the constructive type of fire proofing (Filter route ware, multi-port host computer, host computer screen, subnet screen etc.); the examples of the constructive application of fire proofing; the future developing trend of fire proofing technology and products, etc.So, net security and fireproof technology are the title of this paper. Analogy is applied in this thesis. In Chapter Six, "package filtrate" is the application of the technology.
