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.

Incident response in the cloud


When we speak about cloud computing, we are talking about a shared responsibility (4) between the cloud provider and the company that is contracting the service. The level of responsibility will vary according to the service model, as shown in the following diagram:

For Software as a Service (SaaS), most of the responsibility is on the Cloud Provider; in fact, the customer's responsibility is basically to keep his or her infrastructure on premises protected (including the endpoint that is accessing the cloud resource). For Infrastructure as a Service (IaaS), most of the responsibility lies on the customer's side, including vulnerability and patch management.

Understanding the responsibilities is important in order to understand the data gathering boundaries for incident response purposes. In an IaaS environment, you have full control of the virtual machine and have complete access to all logs provided by the operating system. The only missing information in this...
