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.

BGP hijacking

BGP hijacking in simple terms is defined as the rerouting of the ongoing traffic from one AS to another AS, which is completely owned by the attackers. BGP hijacking is also known as prefix, route, or IP hijacking.

Let’s understand this with a small example. Imagine every day everyone takes different routes from home in the morning to reach the same destination, which only has a single road to go and come back from it. Now, suddenly, one day, a parallel road is designed by hijackers, and as an announcement, a sign has been installed that signals that this is the shortest road to reach the destination, so everybody turns down that newly built road. After this, all of the traffic will eventually be hijacked by the attacker. Let’s frame this with a simple diagram, as shown in the following figure:

As shown in Figure 12.25, an attacker or a hijacker created a fake road just parallel to the...
