Implementing Identity Management on AWS

By: Jon Lehtinen

Overview of this book

AWS identity management offers a powerful yet complex array of native capabilities and connections to existing enterprise identity systems for administrative and application identity use cases. This book breaks down the complexities involved by adopting a use-case-driven approach that helps identity and cloud engineers understand how to use the right mix of native AWS capabilities and external IAM components to achieve the business and security outcomes they want. You will begin by learning about the IAM toolsets and paradigms within AWS. This will allow you to determine how to best leverage them for administrative control, extending workforce identities to the cloud, and using IAM toolsets and paradigms on an app deployed on AWS. Next, the book demonstrates how to extend your on-premise administrative IAM capabilities to the AWS backplane, as well as how to make your workforce identities available for AWS-deployed applications. In the concluding chapters, you’ll learn how to use the native identity services with applications deployed on AWS. By the end of this IAM Amazon Web Services book, you will be able to build enterprise-class solutions for administrative and application identity using AWS IAM tools and external identity systems.

Chapter 4: Access Management, Policies, and Permissions

The Access Management model of AWS is based on policies. At a high level, we can use these policies to determine what an AWS identity object or resource can do to or with a resource or service within an AWS account. Of course, this quickly becomes very complicated once we must apply and manage policies across the multiple places where they may have been applied. We may also need to customize the existing access policies within an AWS account, or even create new policies from scratch to accommodate our own use cases. This chapter does not represent a complete compendium of knowledge regarding the complexities of access management in AWS, but it will introduce you to the foundational concepts required to understand and solve several common authorization use cases.

With this knowledge as your foundation, you will be able to strategically select further areas of study based on your own personal or professional requirements.
