Overview of this book

With the increased demand for computer systems and the ever-evolving internet, network security now plays an even bigger role in securing IT infrastructures against attacks. Equipped with the knowledge of how to find vulnerabilities and infiltrate organizations through their networks, you’ll be able to think like a hacker and safeguard your organization’s network and networking devices. Network Protocols for Security Professionals will show you how. This comprehensive guide gradually increases in complexity, taking you from the basics to advanced concepts. Starting with the structure of data network protocols, devices, and breaches, you’ll become familiar with attacking tools and scripts that take advantage of these breaches. Once you’ve covered the basics, you’ll learn about attacks that target networks and network devices. Your learning journey will get more exciting as you perform eavesdropping, learn data analysis, and use behavior analysis for network forensics. As you progress, you’ll develop a thorough understanding of 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’ll be well versed in network protocol security and security countermeasures to protect network protocols.

Finding Protocol Vulnerabilities

To put it simply, our purpose in finding protocol vulnerabilities is to find weaknesses in the network before someone else finds them. One of the tools that we use for this purpose is called fuzz testing or fuzzing.

In previous chapters, we learned about the data network structure and protocols, security protocols that are implemented in order to protect network resources, and we talked about what tools are available for scanning and testing networks and network devices' vulnerabilities.

In this chapter, we will take you a few steps forward, learning about fuzzing tools and how to use them to exploit the vulnerabilities in network protocols. In this chapter, we will talk about the tools and which one to use in each one of the network layers, while later in this book, we will examine the details of the protocols and learn about vulnerabilities in each one.

In this chapter, we're going to cover the following main topics:
