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 11: Managing Hybrid Clouds

In the previous chapters, we covered cloud infrastructure fundamentals, common threats in cloud environments, how to handle compliance and regulation, and how to engage with cloud providers. In this chapter, we will discuss hybrid clouds.

A hybrid cloud is a combination of an on-premises data center or private cloud and a public cloud environment.

Hybrid cloud is considered an extension of our local data center and, as such, helps us in minimizing the efforts required to control, maintain, and secure our infrastructure and services across the entire hybrid solution.

We are not only extending our local data center infrastructure to the cloud, but we are also extending our security boundaries to the cloud, so we wish to have a central way to control security operations in a hybrid architecture.

In this chapter, we will cover the following topics:

  • Hybrid cloud strategy
  • Identity management over hybrid cloud environments
  • Network...
