AWS Single Sign-On (SSO) Tutorial
1. Introduction
AWS Single Sign-On (SSO) is a cloud service that allows you to manage SSO access to multiple AWS accounts and business applications. It simplifies the user experience by enabling users to log in once and gain access to the resources they need without multiple logins. AWS SSO is relevant for organizations aiming to improve security and efficiency while managing user access across various platforms.
2. AWS Single Sign-On (SSO) Services or Components
AWS SSO consists of several key components:
- User Portal: A centralized place for users to access their applications.
- Identity Source: AWS SSO can integrate with AWS Managed Microsoft AD, external identity providers, or your own identity sources.
- Application Integration: Support for a variety of applications, including AWS services and third-party applications.
- Access Management: Policies and permissions to manage user access effectively.
3. Detailed Step-by-step Instructions
Follow these steps to set up AWS Single Sign-On:
Step 1: Sign in to the AWS Management Console and navigate to AWS SSO.
aws sso-admin create-instance --instance-identifier your-instance-id
Step 2: Choose your identity source.
aws sso-admin update-instance-identity-store --instance-identifier your-instance-id --identity-store-type AWS_MANAGED
Step 3: Configure user access to your applications.
aws sso-admin create-permission-set --name your-permission-set-name --description "Description of permission set"
Step 4: Assign users to the permission set.
aws sso-admin assign-user-to-permission-set --instance-identifier your-instance-id --permission-set-arn your-permission-set-arn --principal-id your-user-id
4. Tools or Platform Support
AWS SSO integrates with various tools and platforms, including:
- AWS Management Console
- AWS CLI
- AWS SDKs
