Authentication and Authorization

InterSystems IRIS® supports a wide variety of authentication mechanisms. Authentication determines if users are who they say they are. Additionally, InterSystems IRIS® supports a robust role-based authorization system, which determines an authenticated user can create, use, view, change, or delete.
