Cloud Security Handbook

Overview of this book

Securing resources in the cloud is challenging, given that each provider has different mechanisms and processes. Cloud Security Handbook helps you to understand how to embed security best practices in each of the infrastructure building blocks that exist in public clouds. This book will enable information security and cloud engineers to recognize the risks involved in public cloud and find out how to implement security controls as they design, build, and maintain environments in the cloud. You'll begin by learning about the shared responsibility model, cloud service models, and cloud deployment models, before getting to grips with the fundamentals of compute, storage, networking, identity management, encryption, and more. Next, you'll explore common threats and discover how to stay in compliance in cloud environments. As you make progress, you'll implement security in small-scale cloud environments through to production-ready large-scale environments, including hybrid clouds and multi-cloud environments. This book not only focuses on cloud services in general, but it also provides actual examples for using AWS, Azure, and GCP built-in services and capabilities. By the end of this cloud security book, you'll have gained a solid understanding of how to implement security in cloud environments effectively.

The MITRE ATT&CK framework

The MITRE ATT&CK framework is a knowledge base of hacking techniques. The cloud matrix of MITRE ATT&CK contains the general flow of cyber attacks:

  • Initial access
  • Execution
  • Persistence
  • Privilege escalation
  • Defense evasion
  • Credential access
  • Discovery
  • Lateral movement
  • Collection
  • Exfiltration
  • Impact

Understanding attack techniques allows us to understand the results of attacks. For example, using the abuse of credentials allows an attacker to gain persistent access to our system.

Another attack example is cloud object storage discovery, which may be used by an attacker to gain access to all objects inside a cloud storage instance.

Reviewing all attack techniques will allow us to understand which security controls we can implement to mitigate potential attacks in our cloud environment, whether that's built-in security tools with AWS, Azure, or GCP, or external third-party tools.
