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 web application communication protocols such as HTTP and HTTP2. We also looked into the security issues caused by HTTP and resolved them by introducing the SSL/TLS certificate embedded in the HTTP, and we came up with a new secured protocol, HTTPS. We also learned about various web application attacks, such as SQL injection, XSS, session hijacking, and buffer overflow, with practical examples. Another service we looked at was email and its corresponding protocols, vulnerabilities, and gateway attacks.

In the next chapter, we will look into more advanced topics such as enterprise security protocols, including LDAP and SMB, their operations, their usage, and their corresponding attacks. We will also look into SQL server attacks, which can leverage an attacker to compromise even a domain admin.
