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.

Cloud connectivity

There are various types of cloud services. The major ones are illustrated in the following diagram:

Figure 1.16 – Cloud-based services

Let's look at the cloud computing services mentioned in the preceding diagram in detail:

  • Infrastructure as a Service (IaaS): These are cloud services that provide us with the hardware and VMs needed to run the environments. We only need to install, configure, and maintain operating systems, applications, data, and user access management when using IaaS.
  • Platform as a Service (PaaS): These are cloud services that provide the platform – that is, the hardware and the operating system – so that the user can install their applications directly.
  • Software as a Service (SaaS): These are cloud services that provide us with the necessary software so that we can connect to the software and work with it.

Now that we've covered the network structure and topologies, network virtualization and how it is implemented, and the different cloud service types and how we connect to the cloud, let's talk about the risks and what can go wrong in each part.
