Introduction to Network Security

Introduction to Network Security focuses on the network and its vulnerabilities, protocols, and security solutions. The book discusses network architecture, the functions of layers in a typical network, and network-based attacks, including header, protocol, and authentication attacks. Using a bottom-up approach, it provides understanding of the vulnerabilities and mechanisms of each layer of network security. A define-attack-defend methodology is used throughout the text to introduce relevant protocols. The author also presents homework problems, laboratory experiments, and appendices that offer an overview of cryptology and demonstrate how to develop a low-cost lab.
