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.

Identity is the new perimeter


As was briefly explained in Chapter 1, Security Posture the protection surrounding the identity must be enhanced, and that's why the industry is in common agreement that identity is the new perimeter. This occurs because every time a new credential is created, the majority of the time this credential is composed only of a username and password. While multifactor authentication is gaining popularity, it is still not the default method used to authenticate users. On top of that, there are lots of legacy systems that rely purely on usernames and passwords in order to work properly.

Credential theft is a growing trend in different scenarios, such as:

  • Enterprise users: Hackers that are trying to gain access to a corporate network and want to infiltrate without making any noise. One of the best ways to do that is by using valid credentials to authenticate, and be part of, the network.
  • Home users: Many banking Trojans, such as the Dridex family, are still actively in...
