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 have focused on multi-cloud environments. We have reviewed the importance of having a multi-cloud strategy to allow organizations to adopt multi-cloud environments. We have also discussed the various IAM solutions from AWS, Azure, and GCP that allow organizations to have a central directory service that can keep a single identity for each end user.

We looked at the various methods that AWS, Azure, and GCP allow organizations to connect between different cloud environments on different cloud providers using a site-to-site VPN tunnel. We also discussed the various data security mechanisms (encryption at transit, encryption at rest, and confidential computing). Then, we reviewed the importance of cost management in multi-cloud environments. We reviewed the concepts of CSPM and CIEM. Finally, we looked at patch management, configuration management, and monitoring in multi-cloud environments.

Understanding the topics mentioned in this chapter will provide...
