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.

Black box, white box, and gray box testing

Fuzzing is what's called black box testing, but before getting into the details, let's understand black box, white box, and gray box testing.

White box testing, also called open box, clear box, or glass box testing, is tests that are performed when we get all the information on the system under test, including software architecture, modules, source code, and so on. White box testing is usually used for software testing, and it is not in the scope of this book.

Black box testing is when you know that the device and/or software you are testing is there, but you don't have any further knowledge of it. You control the input you send into the device; you can see the output that is received, but you don't have any knowledge of the inner architecture and software of the device.

Gray box testing is when you have partial knowledge of the system's internal design and code, such as when we have knowledge of the device...
