Preface

This book talks about the in-depth analysis of network designs and protocols, the corresponding attacks made on them, and the appropriate security measures with a completely practical approach. The first few chapters will talk in depth about the network architectures and how are they designed or monitored. In later chapters, the corresponding attacks on network protocols (such as routing protocols and ARP), device-based attacks (such as on routers or switches), attacks on various technologies such as VOIP and email gateways, web-based attacks, CnC, and data ex-filtrations over network protocols (such as DNS) are demonstrated practically. At the end of each chapter, the steps to protect against such attacks are given.
