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.

Detecting Device-Based Attacks

In the previous chapter, we learned about network-based attacks in which the attacker targets communications lines, and how to protect against them. In this chapter, we talk about attacks targeting network devices and how to harden your network devices against these attacks. By the end of this chapter, you will understand the risks to communications devices and learn how to protect against these risks.

In network devices, we focus on devices that are used for packet switching and forwarding, from simple Layer 2 switches, routers, firewalls, and load balancers to other devices that receive and send packets through the network.

This chapter starts with an explanation of the structure of communications devices— the management, control, and forwarding planes—then, we will drill down into each one, learn about the device resources assigned to each one of them, and learn about the risks and how to protect against them.
