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 block storage

Block storage is a storage scheme like the on-premises Storage Area Network (SAN).

It allows you to mount a volume (disk), format it to a common filesystem (such as NTFS for Windows or Ext4 for Linux), and store various files, databases, or entire operating systems.

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

Best practices for securing Amazon Elastic Block Store

Amazon Elastic Block Store (Amazon EBS) is the AWS block storage.

It is common when working with EC2 instances, to attach an additional volume to store your data (separately from the operating system volume). This is also known as block storage.

Amazon EBS can be attached to a single EC2 instance and can be accessed from within the operating system.

The traffic between your...
