The Handbook of Security will build on the existing Handbook of Data Communications and Networks, and The Complete Handbook of the Internet. It will try to cover every aspect of computer and network security. This will include an analysis of the physical connection and data transfer over networks, the network protocols, the session protocols (such as HTTP and FTP), the network operating systems, network security devices, mobile networks, and an in-depth analysis of the principles and implementation of public-key encryption. Throughout the book practical examples of security will be given, such as router programming commands and screen shots showing key security principles.
