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.

Choosing a cloud provider

Prior to choosing a cloud provider, we need to ask ourselves – what are we trying to achieve from migrating to the cloud or from using the cloud?

There are a few steps that we need to take before we begin working with a cloud provider:

  • Decide on our business goals that the cloud provider will assist us to achieve.
  • Get ourselves familiar with a potential cloud provider and try to understand its maturity level.
  • Sign a contract with a cloud provider that will protect us as customers.
  • Conduct an assessment of the cloud environment to make sure their security controls are effective.

The following diagram illustrates the steps involved while choosing a cloud provider:

What is the most suitable cloud service model for our needs?

This is the first question we need to ask ourselves. If we are still taking the first steps in the cloud, have legacy systems...
