SSO (Single Sign-On) and Identity Federation: A Cloud Engineer's Perspective
- Single Sign-On (SSO) and Identity Federation are key concepts in modern identity management, particularly in cloud-based and hybrid IT environments.
- SSO is an authentication mechanism that allows users to access multiple applications or services with a single set of credentials (e.g., username and password).
- Identity Federation is the process of linking identities across multiple distinct systems or organizations, allowing users to authenticate in one domain and access resources in another without maintaining multiple sets of credentials.
- SSO improves the user experience, reduces IT overhead, enhances security, and simplifies compliance.
- Identity Federation enables cross-domain collaboration, centralized identity management, cloud integration, and scalability.
- The initial setup complexity, single point of failure, security concerns, and interoperability issues are the challenges of implementing SSO and identity federation.
- AWS SSO with Identity Federation is a common use case, requiring setting up SSO, enabling identity federation, integrating Cognito, securing the application, and testing the SSO setup.
- Role-based access control and IAM roles with federated users are crucial for secure access control.
- AWS Cognito is a scalable, customizable, and multi-provider authentication service that integrates directly with AWS services for secure access.
