Network security development and implementation efforts involve the integration of technologies from seemingly unrelated fields that did not previously have to cross paths or internetwork. Areas such as cryptography, network protocols, and switch and router technology each have established theories and practices; developing expertise in all of these fields is a challenging task. Security professionals need a resource that can help them bring all of these security components together for the benefit of their organizations. Network Security Technologies, Second Edition presents key security technologies from diverse fields, using an organized, hierarchical framework that enables you to understand security components, how they relate to one another, and how they interwork. The author delivers a unique presentation of major legacy, state-of-the-art, and emerging network security technologies from all relevant areas, resulting in a useful and easy-to-follow guide. This text is unique in that it classifies technologies as basic, enhanced, integrated, and architectural as a means of associating their functional complexities, providing added insight into their interrelationships. It introduces and details each security technology, then discusses its function so you can more easily grasp the function and importance of each technology within the totality of the network security landscape.
