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.

Hybrid cloud strategy

Before using the hybrid cloud architecture, we need to ask ourselves, what are we trying to achieve through a hybrid cloud solution?

Cloud-native solutions for hybrid environments have the following benefits:

  • Integration of both on-premises resources with cloud resources
  • Built-in integration with cloud services
  • Virtually unlimited capacity (compute and storage) for storing logs and running correlations between events
  • Virtually unlimited storage capacity for storing data (for backups, regulation compliance, disaster recovery, and more)
  • Support for federated identity management (allows a single identity to access resources in hybrid environments)

Let's look at some of the most common use cases for choosing hybrid cloud solutions.

Cloud bursting

The idea behind cloud bursting is to allow applications that run on-premises to burst into the cloud when there is a need for extra resource capacity – both planned and...
