Application Research of Intrusion Prevention System in Emergency Platform Network

With the in-depth construction of the national emergency platform project and the increasingly complex network environment, as well as the increasing diversification of intrusion methods, the defects of traditional firewall technology and intrusion detection system in network security protection are highlighted. The security of traditional network systems is mainly guaranteed by two pillar technologies: firewall and intrusion detection. However, network attack technologies are also constantly developing, and new technologies such as small fragmentation attacks, slow scanning, distributed denial of service attacks, and encryption attacks have emerged. Attack programs for network security software such as firewalls and intrusion detection systems have also emerged, all of which place new demands on the development of network security. This paper first analyzes various network intrusion behaviors, and elaborates the attack characteristics of different intrusion behaviors and the corresponding detection methods and anti-attack methods. Then it introduces the traditional network security defense technology, including password, identity authentication, firewall, intrusion detection, etc., and discusses these passive defense technologies in detail, pointing out their inherent shortcomings.
