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 virtual networking

Each cloud provider has its own implementation of virtual networking.

According to the shared responsibility model, responsibility for the network is split between the cloud provider and the customer. The physical network layer (that is, access between the physical network equipment and physical host servers and storage inside the cloud provider's data centers) is the cloud provider's responsibility.

Virtual networking (such as Amazon VPC, Azure VNet, or Google Cloud Platform (GCP) VPC) is a network layer that is the responsibility of the customers (this layer enables access between virtual servers, managed storage services, managed databases, and more).

Traditional on-premises networking deals with the physical connections between devices in a system: for example, concepts such as virtual local area networks (VLANs) or subnetting, to split a network (with the devices connected to a network) and create network security barriers.
