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.

Implementing Wireless Network Security

In the previous chapter, we learned about network protocols, such as LAN, IP, and TCP/UDP-based attacks, in which the attacker targets network-based protocols, and how to protect against them. This chapter talks about wireless-based attacks and how to harden your wireless networks against them. By the end of this chapter, you will understand the risks to wireless networks and devices and know how to protect against these risks.

In wireless networks, we focus on protocols such as IEEE 802.11, various bands, such as /b/g/n (as discussed in the Wireless standards – IEEE 802.11 section), encryption standards, such as WEP, WPA, and WPA2, and their key weaknesses, such as creating rogue Access Points (APs), dumping hashes, and automating complete tasks. We also need to know how we can protect ourselves against these attacks.

This chapter starts with an explanation of the WLAN protocol—what the WLAN frame constitutes, the frames to...
