Cross-Layer Based Intrusion Detection and Prevention for Network

Abstract

Day by day technologies for mobile computing growing rapidly and its network security changed according to their need. The attacker always trying to learn some new techniques to break those security walls of the wireless network. To prevent our network from attacker various defense techniques are used. Firewalls and encryption are used to prevent our network from malware but it is not sufficient for protecting the networks. Many researchers implement new architecture and techniques or mechanism that protect and detect malicious node and their activity over the network that is intrusion detection system (IDS). IDS provides security wall and it provides network security as well as it has continuously monitored and taken appropriate action against the threat. In this Chapter, we are trying to explain some network attack that is resolved or detect through intrusion detection system by exploiting the technology or information that available across different layers of the protocol stack in order to improve the accuracy of detection.
