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 cloud-based IAM services

Each cloud provider has its own implementation of managed IAM services, in other words, a service for managing authentication and authorization requests.

Here is a list of AWS IAM terminology:

  • IAM user: This is a person or application with permission to access AWS resources. An IAM user has credentials (such as a password, access keys, and MFA).
  • IAM group: This refers to a group of IAM users to make the permissions management task easier.
  • IAM role: This indicates an identity that has permission to access resources without any credentials. Usually, you assign an IAM role to an IAM group, IAM user, or a service account that requires temporary permissions.
  • Service account: This refers to a special type of IAM user, and its purpose is to allow applications to have access to resources.
  • IAM policy: This is a JSON-based definition that sets the permissions for accessing AWS resources. There are two types of IAM policies:
    • Identity...
