Cybersecurity - Attack and Defense Strategies

By: Yuri Diogenes, Dr. Erdal Ozkaya

Overview of this book

The book will start talking about the security posture before moving to Red Team tactics, where you will learn the basic syntax for the Windows and Linux tools that are commonly used to perform the necessary operations. You will also gain hands-on experience of using new Red Team techniques with powerful tools such as python and PowerShell, which will enable you to discover vulnerabilities in your system and how to exploit them. Moving on, you will learn how a system is usually compromised by adversaries, and how they hack user's identity, and the various tools used by the Red Team to find vulnerabilities in a system. In the next section, you will learn about the defense strategies followed by the Blue Team to enhance the overall security of a system. You will also learn about an in-depth strategy to ensure that there are security controls in each network layer, and how you can carry out the recovery process of a compromised system. Finally, you will learn how to create a vulnerability management strategy and the different techniques for manual log analysis.

Strategies for compromising a user's identity


As you can see, identity plays a big role in how hackers gain access to the system and execute their mission, which in most cases is to access privileged data or hijack that data. The Red Team must be aware of all these risks, and how to exploit them during the attack exercise. For this reason, it is important to establish a plan of attack before we start acting. This plan should take into consideration the current threat landscape, which includes three stages:

During Stage 1, the Red Team will study the different adversaries that the company has. In other words, who can potentially attack us? The first step to answer this question is to perform a self-assessment and understand what type of information the company has, and who would benefit from obtaining it. You might not be able to map all adversaries, but at least you will be able to create a basic adversary profile, and based on that you can move on to the next stage.

In Stage 2, the Red Team...
