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.

Attacks on the control plane and how to defend against them

The control plane, as we saw earlier in this chapter, contains the protocols and processes that communicate between network devices in order to move packets from end to end through the network. In this category, we have Layer 2 protocols such as the Spanning Tree Protocol (STP)/Rapid STP (RSTP); Layer 3 routing protocols that learn network topologies such as the Cisco Discovery Protocol (CDP) or the Link Layer Discovery Protocol (LLDP) that advertise equipment information to their neighbors; the Resource Reservation Protocol (RSVP) that establishes a guaranteed end-to-end (E2E) channel with pre-defined QoS; the Internet Control Message Protocol (ICMP) that is used for network reachability testing; and others.

In Chapter 10, Discovering LAN, IP, and TCP/UDP-Based Attacks, and in Chapter 12, Attacking Routing Protocols, we will get into the details of how to protect the network protocols themselves. What we talk about in...
