Section 1: Network and Security Concepts

This section will be begin by introducing the reader to the fundamentals of security, security deployment models, factors, key terminology that is important to a security analyst, principles of defense in depth in security, and various access control models.
This section contains the following chapters:
  • Chapter 1, Exploring Networking Concepts
  • Chapter 2, Exploring Network Components and Security Systems
  • Chapter 3, Discovering Security Concepts

Chapter 1: Exploring Networking Concepts

As an up-and-coming cybersecurity professional, it is important to have a solid foundation of the understanding of networking concepts such as the types of devices, the underlying network layers, and the protocols that help transport messages from a source to a destination. Understanding networking concepts helps a security professional to better grasp the fundamentals of knowing how threat actors, such as hackers, are able to discover security flaws in applications, operating systems, and network protocols. Hackers use these vulnerabilities to assist in delivering their malicious payload into their targets.
Throughout this chapter, you will learn about various networking technologies, protocols, and services, and how they all work together to forward your messages, such as data, between your device and the destination. As a cybersecurity professional, it is essential to fully understand how network devices and protocols function. To put it simply, many network protocols were not designed with security in mind, and threat actors usually take advantage of the vulnerabilities found within these technologies. Upon completing this chapter, you will be able to fully understand the networking aspects of cybersecurity, which many professionals struggle to grasp.
In this chapter, we will cover the following topics:
  • The functions of the network layers
  • Understanding the purpose of various network protocols
Now that we are aware of the outcomes we are set to achieve, let's dive into the chapter!

The functions of the network layers

Networking plays a vital role in everything we do on a daily basis. Whether your organization is using Slack or Microsoft Teams or traditional emails for internal communication between employees, your smartphone or computer is connected to a network. To fully understand how cyber-attacks and threats are able to infiltrate a system or network, you must first understand the fundamentals of networking.
Hackers are cunning; they are always looking for the easiest way to gain access to a system or network. They look for vulnerabilities, which are security weaknesses in a system, application, coding, or design, and try to take advantage by exploiting them. You may be wondering, what does this have to do with networking? To answer this question in a simple sentence, there are many network protocols that were not designed with any security in mind, thus allowing hackers to exploit their vulnerabilities.
To get a better understanding of the bigger picture of network protocols and applications, let's take a look at what happens when a device such as a computer sends a message such as data to a web server. Built into each modern operating system, whether it's Microsoft Windows, Apple macOS, or even the Android operating system, you will find a protocol suite, which is responsible for the encoding, formatting, and transmission of messages between a source and destination.
During the pre-internet age and the early stages of computer networks, many computer vendors created their own protocol suite to enable their devices to communicate on a network. The downside to such ideas was that each vendor made a protocol suite proprietary to their devices only. This means Vendor A devices would not be able to communicate with Vendor B devices if they were connected to the same physical network.
This concept was not scalable or adaptive. Eventually, two emerging protocol suites surfaced with promises to be interoperable with any vendor devices and networks. These two well-known protocol suites are as follows:
  • The Open Systems Interconnection (OSI) reference model
  • The Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite
A protocol suite allows a device to format a message for delivery using a universal set of standards and protocols to ensure all devices along the path to the destination are able to read the addressing and data contents clearly. In other words, the protocol sui...
