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.

Analyzing current trends


Over time, hackers have proven to cyber security experts that they can be persistent, more creative, and increasingly sophisticated with their attacks. They have learned how to adapt to changes in the IT landscape so that they can always be effective when they launch attacks. Even though there is no Moore's law, or its equivalent in the context of cyberattacks, it can be said that hacking techniques become more sophisticated each year. In the last few years, there has been an observed trend in terms of the preferred attacks and modes of execution. These include:

Extortion attacks

Previously, in most instances, hackers have been getting revenues for selling stolen data from companies. However, in the last three years, they have been seen using another tactic: extorting money directly from their victims. They may either hold computer files to ransom or threaten to release damaging information about a victim to the public. In both instances, they request money to be paid...
