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.

Implementing fine-grained access management for administrators

So far, we only have two levels of access for our administrators inside our AWS accounts once those administrators are placed inside a group that allows them to sign in to AWS SSO: AdministratorAccess and ReadOnly. If we defined group-based access that determines if a user is permitted to even access AWS SSO as coarse-grained access management, then the access granted by these two permission sets represents a very rudimentary example of role-based access control (RBAC). By layering on additional concepts, we can further refine our authorization model into something that is only allowed access to specific resources based upon the assumed role and the user's attributes, to achieve fine-grained access management through attribute-based access control (ABAC).

Permission sets and managed authorization policies

To achieve fine-grained access management through ABAC, we will need to marry an improved set of permission...
