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.

Compliance and the shared responsibility model

According to the shared responsibility model (as explained in Chapter 1, Introduction to Cloud Security), the cloud provider in infrastructure as a service/platform as a service (IaaS/PaaS) is responsible for the physical aspects of the cloud (from physical data centers, hardware, storage, network equipment, host servers, to virtualization).

Software as a service (SaaS) providers are also responsible for application layers (guest operating system (OS), managed databases, managed storage, application tier, and more). As customers, we expect our cloud providers to be both compliant with regulatory requirements (such as protecting credit card information in PCI DSS, protecting personally identifiable information (PII) in GDPR, and more) and to work according to the highest security standards (such as ISO 27001, SOC, and more).

When we as organizations serve customers, we need to be compliant with regulations (when dealing with financial...
