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.

Identity management over multi-cloud environments

One of the first things to decide on, prior to using a multi-cloud strategy, is identity management. Organizations would like to keep their existing Identity Provider (IdP), have a single identity for each of their end users (while preserving existing credentials), and still be able to access resources in the cloud. If an organization is already using Office 365 for managing mailboxes and collaboration, consider using Azure Active Directory (AAD) and its central identity management service.

Azure AD is considered the most used IdP. It supports identity federation to most major cloud providers and is able to integrate with most Software as a Service (SaaS) solutions. Other popular identity management providers that are outside the scope of this book are Okta, Ping Identity, and OneLogin, which allow you a universal directory service for managing your users, groups, and devices, enforcement of Multi-Factor Authentication (MFA), and...
