What is SCIM?
System for Cross-domain Identity Management (SCIM) is an open standard protocol that is designed to simplify the management of user identities across different systems and domains. SCIM is particularly useful in the context of identity and access management, where organizations need to manage user accounts, roles, and other identity-related information across various applications and services.
SCIM provides a standardized way to create, read, update, and delete (CRUD) user identities and associated data, such as groups and roles. It is commonly used in scenarios where user information needs to be synchronized between different systems, such as between an organization’s HR systems, email services, and cloud-based applications.
Key features and concepts of SCIM include the following:
- Resources. SCIM defines various types of resources such as users, groups, and schemas, which represent different aspects of identity and access management. These resources can be manipulated using standard HTTP methods (GET, POST, PUT, DELETE).
- Attributes. SCIM specifies a set of common attributes that can be used to describe user identities. These attributes can be extended to support custom attributes as needed.
- Filters. SCIM supports filtering to retrieve specific sets of resources based on certain criteria, making it easier to find and manage identities.
- Pagination. For large datasets, SCIM supports pagination to retrieve data in smaller, manageable chunks.
- Schema. SCIM uses a schema to define the structure and attributes of resources, ensuring consistency and compatibility across systems.
- Authentication and Authorization. SCIM doesn’t prescribe a specific authentication or authorization mechanism. It can work with various authentication methods, including OAuth, to ensure secure access to identity resources.
- Error Handling. SCIM defines a set of error codes and messages for handling errors in a standardized way.
SCIM is commonly used in identity and access management (IAM) solutions and is particularly valuable in scenarios where multiple applications or services need to share user data and where interoperability and standardization are important. By implementing SCIM, organizations can reduce the complexity of managing user identities across different systems, leading to improved security and operational efficiency.
SCIM has gained widespread adoption and is supported by many IAM vendors and cloud service providers, making it a valuable tool for modern identity management.
