AWS IAM Identity Center (AWS SSO)

Why AWS IAM Identity Center is Important:
AWS IAM Identity Center, formerly known as AWS Single Sign-On (AWS SSO), is a crucial service for managing user access and permissions across multiple AWS accounts and business applications. It simplifies identity management, enhances security, and improves user experience by providing a centralized access point.

What is AWS IAM Identity Center?
AWS IAM Identity Center is a cloud-based service that enables single sign-on access to multiple AWS accounts and third-party applications. It allows users to sign in once with their corporate credentials and gain access to all assigned AWS accounts and resources without the need for multiple login credentials.

How AWS IAM Identity Center Works:
1. Users are authenticated through their corporate directory (e.g., Active Directory) or an external identity provider (IdP) that supports SAML 2.0.
2. AWS IAM Identity Center federates the user identities and provides them with temporary AWS credentials.
3. Users can access assigned AWS accounts and resources using the AWS Management Console, CLI, or API.
4. Permissions are managed centrally through permission sets, which define the actions users can perform in each AWS account.

Answering Questions on AWS IAM Identity Center in an Exam:
1. Understand the purpose and benefits of AWS IAM Identity Center, such as centralized access management, reduced administrative overhead, and improved security.
2. Know how AWS IAM Identity Center integrates with corporate directories and external identity providers.
3. Familiarize yourself with the concept of permission sets and how they control user access to AWS resources.
4. Recognize scenarios where AWS IAM Identity Center is the most suitable solution for managing user access across multiple AWS accounts and applications.
