Discover network-based attacks and learn to defend your organization's network and network devices Key Features Exploit vulnerabilities and use custom modules and scripts to crack authentication protocols Safeguard against web, mail, database, DNS, voice, video, and collaboration server attacks Monitor and protect against brute-force attacks by implementing defense mechanisms Book Description Network security plays an important role in securing IT infrastructures against attacks. The increased demand for computer systems, and the ever-evolving internet, has allowed people to find vulnerabilities and infiltrate into organizations through their network. Network Protocol Security will help you safeguard your organization's network and networking devices. This book is a comprehensive guide that begins with the basics, gradually increases in complexity, and later takes you through advanced concepts. You will start by understanding the structure of data network protocols and devices as well as breaches. In addition to this, you’ll become familiar with attacking tools and scripts that take advantage of these breaches. After covering the basics, you will learn attacks that target networks and network devices. Next, you will perform eavesdropping, learn data analysis, and use behavior analysis for network forensics. Toward the concluding chapters, you will understand network protocols and how to use methods and tools you learned in the previous parts to attack and protect these protocols. By the end of this network security book, you will have learned network protocol security and security counter-measures to protect network protocols. What you will learn Understand security breaches, weaknesses, and protection techniques Attack and defend wired as well as wireless networks Discover how to attack and defend LAN, IP, and TCP/UDP-based vulnerabilities Focus on encryption, authorization, and authentication principles Gain insights into implementing security protocols the right way Use tools and scripts to perform attacks on network devices Wield Python, PyShark, and other scripting tools for packet analysis Identify attacks on web servers to secure web and email services Who This Book Is For This book is for red team and blue team pentesters, security professionals, or bug hunters. Anyone involved in network protocol management and security will also benefit from this book. Basic experience in network security will be an added advantage.
