A Study And Implementation Of Deep Defense Method For Networks

Computer networking is one of the fastest growing technologies in the modern world today, and it makes human life more convenient than before. While there are still some hackers doing kinds of destructs by using the security holes, so network security is the most important issue that we now pay more attention to.Firewall and Intrusion Detection System are the important traditional methods to protect network from being intruded. The goal of these methods is to keep intrusion out of the network that we want to protect. We can build a relatively perfect defense system by using firewall and IDS. This thesis aims to research the method of instructing a network security defense system in depth on the basis of firewall and Intrusion Detection System and a sample is discussed in this method.This paper based on three layers of theories rules, technology method and concrete realization, A kind of method research and solutions design of is discussed in detail on how to instruct a system of Defense in Depth.
