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.

Network Protocol Structures and Operations

In Chapter 1, Data Centers and the Enterprise Network Architecture and its Components, we discussed network architectures and how an organization's network is built. In this chapter, we will take a look at the protocols that work in the network, and we will examine the vulnerabilities and potential risks of each of them.

In this chapter, we will cover network protocols and the risks of not properly securing each one of them. Additionally, we will examine the potential risks, while, in the later protocol chapters, we will explore how to attack them and how to protect against these attacks.

We will begin with the Open Systems Interconnection Reference Model (OSI-RM) and data flow through the network. Then, we will go through each of the layers, from layer 2 to the application layers, exploring the protocol structures and potential risks for each layer and protocol.

In this chapter, we're going to focus on the following main...
