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.

Cloud Security Posture Management (CSPM)

As part of having visibility in your multi-cloud environments, over the past couple of years, a new concept has emerged.

There are multiple offers from many third-party CSPM vendors, but the fundamental idea behind all CSPM solutions is to have visibility of misconfigurations – a crucial topic when working in a multi-cloud environment and managing multiple cloud accounts. When selecting a CSPM solution, look for the following capabilities:

  • Support for multiple cloud providers.
  • Visibility of misconfigurations (such as an opened port and publicly accessible object storage).
  • Visibility of IAM (such as API keys located in publicly accessible object storage, access keys or passwords that were not rotated in the past 90 days, users' permissions, and accounts missing MFA).
  • Visibility of your entire cloud assets across a multi-cloud environment.
  • The ability to assess risks over your entire multi-cloud environment...
