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.

Detecting and mitigating data breaches in cloud services

A data breach, as its name implies, is the unauthorized access of an organization's data. This can result in the exposure of customer or employee personal data and lead to reputational damage for an organization. Because of the shared responsibility model of cloud computing, we need to think differently about data breaches. For example, we do not control the physical storage of our data. This presents a different threat model when compared to a traditional on-premises data center we manage. Data breaches are more likely when working with public cloud services because in this case, we don't control the physical storage of our data. Does this mean that storing our data in the cloud makes it more prone to data breaches? It depends on the cloud service model and on the maturity of the cloud service provider. According to the shared responsibility model, when using an infrastructure as a service (IaaS) solution, we (customers...
