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.

Introduction to IAM

Identity and Access Management (IAM) refers to the concept of managing the entire user life cycle, including provisioning (that is, account creation), assigning permissions, and, finally, account deprovisioning (that is, when a person leaves the organization, or the account is no longer necessary).

Access management is made up of the following main concepts:

  • Identity: This indicates a user, computer, service, or role that wishes to access a system or application and take actions (from accessing shared storage to querying a database and pulling information).
  • Authentication: This is the process of proving that a specific identity (such as a user) is who they claim to be (for example, providing a username and password that match the user's records on a central user repository).
  • Authorization: This is the process of granting an authenticated identity (such as a user) the permissions to take actions on a resource (such as allowing a user to upload...
