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.

HTTP and HTTP2 protocol behavior, data structure, and analysis

In this section, we talk about various web protocols, such as HTTP and HTTP2, what the difference is between HTTP and HTTP2, the architecture, and various functional and security issues in both protocols.

HTTP behavior, data structure, and analysis

HTTP or HyperText Transfer Protocol is used to exchange data between a client and a server in the form of HyperText Markup language (HTML) documents. These documents include images, text, video files, and flash files. HTTP works on the top of all the network layers and is known as the Application Layer, and it is used to transfer all data between the connecting networking devices.

HTTP was introduced back in the late 1980s and early 1990s, but with modifications, the final version of HTTP/1.1 was submitted in 1997, which is still the standardized version of the HTTP protocol. To learn more about the history and developments of HTTP, there is an interesting blog written...
