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.

Scoping the issue


Let's face it, not every incident is a security-related incident and, for this reason, it is vital to scope the issue prior to start an investigation. Sometimes, the symptoms may lead you to initially think that you are dealing with a security-related problem, but as you ask more questions and collect more data, you may realize that the problem was not really related to security.

For this reason, the initial triage of the case has an important role on how the investigation will succeed. If you have no real evidence that you are dealing with a security issue other than the end user opening an incident saying that his computer is running slow and he thinks it is compromised, than you should start with basic performance troubleshooting, rather than dispatching a security responder to initiate an investigation. For this reason, IT, operations, and security must be fully aligned to avoid false positive dispatches, which results in utilizing a security resource to perform a support...
