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.

Summary

In this chapter, we focused on the various encryption alternatives based on AWS, Azure, and GCP.

We began by introducing the concepts of encryption (symmetric and asymmetric algorithms). We continued by introducing the best practices for using KMSes (access control, auditing, and monitoring). Then, we started talking about secrets management services (access control, auditing, and monitoring).

Throughout this chapter, we had a long discussion about encryption in transit and encryption at rest, and we concluded with a short conversation about encryption in use. Following the shared responsibility model, customers can use their own encryption keys, which increases their ability to control the data that's stored in the cloud.

Knowing about the available options for encryption will allow you to choose the most suitable solution for each service you are using in the cloud.

In the next chapter, we will review common security threats to cloud computing (data breaches...
