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.

Securing object storage

Each cloud provider has its own implementation of object storage, but at the end of the day, the basic idea is the same:

  • Object storage is a special type of storage that is meant to store data.
  • Files (or objects) are stored inside buckets (these are logical concepts such as directories or logical containers).
  • Access to files on object storage is either done through the HTTP(S) protocol API via web command-line tools or programmatically using SDK tools.
  • Object storage is not meant to store operating systems or databases (please refer to the Securing block storage section).

Next, we are going to examine what the best practices are for securing object storage services from AWS, Azure, and GCP.
