SHARE ON:

As your organization expands its tech stack, sharing user data between tools becomes challenging. SCIM provisioning, a standard for cross-domain identity management, is designed to simplify employee access management. It streamlines tasks, making user management more efficient and reducing the risk of errors throughout the process.

The growing use of SaaS applications for better productivity and business expansion is clear. However, with sensitive customer data and valuable corporate data in these apps, ensuring secure and compliant access management is crucial. It's vital to streamline user provisioning and deprovisioning for creating, managing, and removing user accounts, profiles, and permissions across the corporate IT landscape, including SaaS apps.

Automating these processes is crucial to cut costs, minimize human error, and enhance security and scalability. That's where SCIM, or System for Cross-domain Identity Management, plays a crucial role. SCIM provisioning is an automated process that manages user accounts and access rights across systems using the SCIM protocol.

This blog discusses the intricacies of SCIM provisioning and how it differs from API-based provisioning. So, let's get started.

What is SCIM Provisioning?

SCIM, or System for Cross-Domain Identity Management, is a standardized protocol that automates user identity management tasks across diverse systems and domains. Its primary goal is to standardize and make the provisioning and de-provisioning of user accounts interoperable. In short, SCIM simplifies the management of user accounts and grants access rights using its standardized protocol.

SCIM Provisioning acts as a bridge between cloud-based applications, fostering a seamless connection between the Identity Provider (where user data is stored) and the Service Provider (SaaS apps like Salesforce, AWS, Zoom, etc.). 

Once SCIM Provisioning is set up, any 'Create,' 'Update,' or 'Delete' actions performed in the Identity Provider automatically synchronize with the Service Providers. In simpler terms, changes made to user data in the central platform are reflected instantly in various SaaS apps. This enhances data security and simplifies the management of user lifecycles.

Key Features of SCIM Provisioning

Key features of SCIM provisioning include:

• Standardized Protocol: SCIM provisioning provides a standardized set of rules and conventions for exchanging user identity information between identity providers (such as an organization's user directory) and service providers (applications or external systems that require user identity data).

• User Lifecycle Management: SCIM enables organizations to manage the entire lifecycle of user accounts, from creation and modification to deactivation or deletion. This helps in maintaining accurate and up-to-date user information across various platforms.

• Cross-Domain Integration: SCIM is particularly useful in scenarios where multiple domains or systems need to synchronize user identity data. It promotes interoperability by offering a consistent approach to identity management across different environments.

• Efficient Automation: By automating identity management tasks, SCIM reduces the manual effort required for provisioning and ensures that changes in user status are reflected promptly across connected systems.

• Interoperability: SCIM's standardized approach ensures interoperability between identity management and service systems supporting the protocol. This allows organizations to integrate various cloud applications seamlessly.

• Security: SCIM implementations often prioritize security, ensuring that user identity information is exchanged securely and authentically.

In short, SCIM provisioning simplifies the process of managing user identities in a cross-domain environment, offering a standardized and efficient solution for organizations that need to synchronize user data across various platforms and systems.

How Does SCIM Provisioning Work?

SCIM provisioning works by automating the exchange of user identity data between a client, such as a corporate identity and access management system or a third-party identity provider, and a service provider, like a SaaS vendor. It establishes a standardized schema for exchanging identity data items with SaaS applications, such as usernames or user IDs.

Utilizing a REST API, SCIM enables CRUD (Create, Read, Update, and Delete) actions to manage data throughout the entire identity lifecycle. The core concept is that SCIM ensures automatic synchronization, via the REST API, of any actions initiated on the client side, such as creating, updating, or deleting an account, with the service provider side (SaaS vendor), ensuring both remain aligned and up-to-date.

Let's consider an example involving SCIM Provisioning:

Imagine you're using an identity provider (IDP) to store user data, and you want to seamlessly integrate this data with various Software as a Service (SaaS) applications, such as Salesforce, AWS, and Zoom. By implementing SCIM Provisioning:

• Create Operation:

You add a new user to your IDP.

The SCIM-enabled IDP triggers a 'Create' operation by sending a request to the SCIM API endpoint of the SaaS apps you wish to access.

• Update Operation:

You modify user details in the IDP (e.g., change role or permissions).

The SCIM-enabled IDP initiates an 'Update' operation, automatically synchronizing the updated information with the corresponding user accounts in the connected SaaS applications.

• Delete Operation:

If a user leaves the organization, you remove their account from the IDP.

The SCIM-enabled IDP triggers a 'Delete' operation, promptly deprovisioning the user from the associated SaaS applications.

That's how SCIM Provisioning streamlines user account management across different systems, ensuring consistency and security in user data synchronization.

Key Advantages Of SCIM Provisioning 

SCIM provisioning offers a secure and efficient method for automating user onboarding across different domains, eliminating the necessity for costly custom integration and managing proprietary APIs. The synchronization between identity providers and SaaS providers aims to minimize operational costs and facilitate swift onboarding and offboarding processes.
