Cloud Security Handbook

By: Eyal Estrin

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.

Chapter 13:Security in Large-Scale Environments

In the previous chapters, we covered cloud services, right from the basic building blocks (such as compute, network, storage, and security) to hybrid and multi-cloud architectures.

In the final chapter of this book, we will cover security in large-scale environments. Previously, we looked at managing an account based on a single cloud provider while having all the resources located in a single place. In this chapter, we will zoom out of this picture and look at large-scale cloud environments – having multiple accounts, for different departments or different business needs, often in multiple regions around the world.

The following are some of the questions organizations often ask themselves:

  • How do I enforce governance over multiple accounts?
  • How do I get visibility into my entire cloud environment?
  • How do I manage a multi-region environment?
  • What automation capabilities do I have?
