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.

Person-in-the-Middle (PITM) attacks

These types of attacks in wireless networks are based on attacking users rather than APs; this includes users who might have connected to open networks or our target networks anytime in the past. These attacks come in handy when we are targeting the users of an organization. Let's say we are targeting organization A, and we know an employee who goes to Starbucks at the end of the day to grab a cup of coffee, work on their emails, and open some of their internal organization's websites, perhaps for timesheet entry. So, rather than directly targeting the organization, we can target that user by probing the list of the organization's wireless network, and then capturing or monitoring the user's activity.

The following are some of the attacks that we can perform in our day-to-day red team activity:

  • KARMA: KARMA is a different type of evil twin attack in which an attacker listens to all the probe messages that the client...
