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.

Obfuscation


This is the last stage of the attack which some attackers may choose to ignore. The main aim here is for the attackers to cover their tracks for various reasons. If the attackers do not want to be known, they use various techniques to confuse, deter, or divert the forensic investigation process that follows a cyber-attack. Some attackers may, however, opt to leave their trails unmasked if they operated anonymously or want to boast of their exploits.

Obfuscation is done in a number of ways. One of the ways that attackers prevent their adversaries from catching up with them is by obfuscating their origins. There are a number of ways through which this can be achieved. Hackers at times attack outdated servers in small businesses and then laterally move to attack other servers or targets. Therefore, the origins of the attacks will be tracked down to the servers of the innocent small business that does not regularly perform updates.

This type of obfuscation was recently witnessed in...
