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.

In this chapter, we focused on large-scale cloud environments that contain multiple accounts.

We discussed how to deploy a multi-account organizational structure and how to set policies to check and enforce compliance over our entire organization.

Then, we learned how to achieve automation in cloud environments using IaC – from built-in services from AWS, Azure, and GCP, to a more cloud-agnostic solution called Terraform.

Finally, we reviewed security-related services from AWS, Azure, and GCP that allow us to maintain patch management, compliance, and threat management over large organizations containing multiple accounts/subscriptions/projects from a central place.

The information in this chapter should have helped you learn how to manage security in large cloud environments.
