Research on Constructing an Internet - based Multi - step Security System

Due to the side effects of the increasing Internet population and the proliferation of new cyberspace culture on the current Internet culture, this research seeks to construct a multi-step security system as a counter measure. This multi-step security system utilizes the existing legacy security solution firewall, intrusion detection system, and intrusion prevention system and virus wall to provide a new security system, which maximizes the effectiveness of the entire system, and also presents an ideal security system by enforcing security steps. It is also a momentous security system model which can successfully defend the system from hacking, worm virus, spam mails, and DDoS attack..
