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.

Storage services for hybrid cloud environments

Now that we have decided on an identity management and network topology, the next thing we need to consider is how to use hybrid clouds for data transfer and storage.

In this section, we will review the various options for data transfer.

When considering hybrid storage connectivity, consider the following:

  • Bandwidth/latency/time to transfer
  • Use of public versus private connectivity
  • Moving files versus file synchronization
  • Encryption requirements (in transit and at rest)
  • Access control for a hybrid solution
  • Supported protocols (NFS, CIFS, and more)

How to connect to storage services over AWS hybrid environments

Amazon offers the following services to transfer data to the cloud in a hybrid architecture:

  • AWS Storage Gateway: A virtual appliance for installing on-premises environments that allows access from the on-premises environments to an object storage service (Amazon S3/Glacier), file...
