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:
