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.

Summary

In this chapter, we discussed network-based attacks, that is, attacks that target network resources in order to prevent users from using the network.

We examined two major types of attacks – those that simply load the network to the point that users are not able to use them, and the network protocol-based attacks that target basic network functionality, such as ARP and DHCP, in an attempt to prevent the network from functioning.

In this chapter, you learned how to use traffic-generation tools and tools that are used to generate attacks on Layer-2 and Layer-3 protocols. Additionally, you learned how to protect against them.

In the next chapter, we will learn about attacks on network devices, how to perform them, how to discover them, and how to defend against them.
