Security - SAML 2.0 IdP Integration

Introduction

ModelOp Center integrates with SAML 2.0 to enable enterprise-grade authentication and access control, allowing isolation of models by authorized groups.

Overview

The saml-support-service is an optional microservice in the ModelOp Center install. This service is the bridge between components using SAML 2.0 and components using OAuth 2.x. The roles of the saml-support-service include:

1. SAML 2.0 Service Provider (SP)

2. OAuth 2.x Authorization Server (AS).

When in the role of SP, the saml-support-service is responsible for initiating user authentication with a SAML request to the SAML identity provider (IdP). After receiving the SAML assertion, the saml-support-service validates it and parses the necessary information: the username, user attributes, etc.

When in the role of AS, the saml-support-service is responsible for creating OAuth 2.x tokens. The payload of the OAuth 2.x tokens will include the parsed necessary information from the SAML assertion.

The implementation of both roles is done using Spring.

ForgeRock: The SAML IdP responsible for authenticating users on behalf of ModelOp Center as well as providing necessary user information as part of the SAML assertion.
