Federation
(OBJ 4.6)
Federation
- Links electronic identities and attributes across multiple identity management systems
- Enables users to use the same credentials for login across systems managed by different organizations
- Based on trust relationships between systems
- Federation extends beyond an organization's boundaries
- Partners
- Suppliers
- Customers
- Simplifies user access to various services
- A supplier or costumer can authenticate using their own network credentials
- Ensures security through trust relationships between networks
- To Configure a federation across multiple organizational networks, we usually rely on a technology like
- SAML
- OAuth
- OpenID Connect
Federation Process
- Login Initiation
- User accesses a service or application and chooses to log in Redirection to Identity Provider
- Service Provider (SP) redirects the user to their Identity Provider (IdP) for authentication
- Authentication of the user
- IdP validates the user's identity using stored credentials
- Validates the user’s identity
- Generation of Assertion
- IdP creates an assertion (token) with user identity and authentication status in a standardized format
- Return to Service Provider
- User returns to the original service or application with the assertion from the IdP
- Verification and Access
- Service Provider verifies the assertion and grants access based on the information it contains
- Login Complete
- User gains access to the service or application and potentially others within the federation without additional logins
Benefits
- Simplified user experience
- Reduced administrative overhead
- Increased security through reduced password reuse and improved management
