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 file storage

File storage is a piece of storage such as the on-premises network-attached storage (NAS).

Each cloud provider has its own implementation of file storage, but at the end of the day, the basic idea of file storage are described as follows:

  • They offer support for common file sharing protocols (such as NFS and SMB/CIFS).
  • They have the ability to mount a volume from a managed file service into an operating system to store and retrieve files, for multiple VMs, in parallel.
  • They have the ability to control access permissions to the remote filesystem.
  • They enable automatic filesystem growth.

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