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 7: Applying Encryption in Cloud Services

In Chapter 2, Securing Compute Services, to Chapter 6, Monitoring and Auditing Your Cloud Environments, we covered the fundamental building blocks of cloud services (from compute, storage, and networking services to Identity and Access Management (IAM) services, to auditing, threat management, and incident response).

This chapter will cover various concepts regarding encryption – including the differences between symmetric and asymmetric encryption, Key Management Services (KMSes), secrets management services, and using encryption in transit and at rest in cloud environments.

Since encryption is a common security best practice that is used to allow data confidentiality, and since many cloud services already have built-in support for encryption (unlike on-premises environments, which require a lot of effort to maintain encryption keys), it is crucial to understand how encryption works and how it is implemented in the various...
