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.

Summary

In this chapter, we have learned about various wireless standards and loopholes or misconfigurations that can lead to serious network hijacks. As, nowadays, almost all organizations implement production environments or corporate networks on wireless networks, it is very important to protect wireless perimeters from attackers. The most common way to compromise a wireless network is by cracking the password; once the attacker has guessed the password, there is no way to stop them from compromising the corporate network. Hence, the passphrase implemented should be strong. Another common attack that attackers use if they are not able to compromise the wireless network is to create an evil twin to let users connect to that evil twin's SSID. Therefore, to protect against such attacks, WIPS plays an important role, triggering a fake AP based on multiple parameters, such as BSSID. Implementing a secure wireless network is a bit of a tedious task, but not that difficult. Therefore...
