Although open source network security tools come in all shapes and sizes, a company will eventually discover that these tools are lacking in some area—whether it’s additional functionality, a specific feature, or a narrower scope. Written by security expert Mike Schiffman, this comprehensive book will show you how to build your own network security tools that meet the needs of your company. To accomplish this, you’ll first learn about the Network Security Tool Paradigm in addition to currently available components including libcap, libnet, libnids, libsf, libdnet, and OpenSSL. Schiffman offers a detailed discussion of these components, helping you gain a better understanding of the native datatypes and exported functions. Next, you’ll find several key techniques that are built from the components as well as easy-to-parse programming examples. The book then ties the model, code, and concepts together, explaining how you can use this information to craft intricate and robust security systems.
