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.

Wireless standards, protocols, and encryption standards

In this section, we will talk about wireless standards, such as IEEE 802.11, and amendments, also known as wireless bands a/b/g/n/f, and their corresponding frequencies on which wireless or Wi-Fi operate in different countries or zones. So, let's try to understand the various standards of wireless and amendments.

Wireless standards – IEEE 802.11

IEEE stands for Institute of Electrical and Electronics Engineering. Now, the 802.11 standard is split up into two anomalies, named committees and working groups:

  • 802 is a committee formed for all network-related norms.
  • 11 is a working group specially designed for wireless LAN.

Now, these standards have some amendments built in and are represented as 802.11/b/g/n/ac/ad/a, which are normally in practice.

The following are some of the frequency bands that are commonly used around the globe:
