What is SCIM Provisioning: In-Depth Guide [2024]

The ability to outsource and automate repetitive daily tasks is at the core of why scim provisioning exists.

In the case of large and medium scale enterprises, when an employee joins a new company for example, they usually require access to all of the necessary tools needed to perform their duties.

This then means that new accounts have to be created with all the right user privileges and packages.

We could flashback to the pandemic when everyone practically went remote and we had to rely on a bunch of software tools to stay productive at work.

Even now, employees of large and medium firms still rely on several different cloud based apps to carry out their daily jobs.

However, we can imagine that when dealing with thousands of users spanning several different cloud based user accounts, this repetitive cycle of handling new cloud identities can easily get complex and untidy if not properly automated. Besides, it could create footprints for security attacks.

What is SCIM provisioning?

One effective way to solve this problem of creating many different user accounts per need is through SCIM provisioning. SCIM provisioning involves setting up an automated workflow that caters to the following needs:

1. Assigning new user accounts or provisioning users
2. Updating roles and access levels as needed
3. Safely removing user identites when they are no longer in use, also known as de-provisioning users.

The System for Cross-domain Identity Management(SCIM) is an open web standard that serves this purpose of providing a way to easily authenticate users of your app across third party services.

How SCIM Works

The SCIM server is a made up of restful API with available endpoints. Information is exchanged over a secure communication protocol. The SCIM client is expected to make a HTTP request call to the server and receive a matching response.

By providing a standardized API and data model, SCIM makes automated user provisioning, de-provisioning and management possible across various clouds apps.

Let's throw more light into the illustration above. We usually have 3 key players involved in the workflow of creating user accounts (otherwise called provisioning) using SCIM standard:

1. the SCIM Client which is the Identity Service Provider (IdP)
2. the SCIM service provider
3. and the cloud apps.

The IdP which has a record of the organizations' user identities initiates requests to the SCIM service provider. Next, the SCIM service provider makes the appropriate changes automatically to all the connected cloud applications.

SCIM defines resources such as User, Group, and ServiceProviderConfig

Each of these resources we just mentioned come with a set of attributes. For example, a User resource includes attributes like userName, emails, displayName, name.

We can also extend the schema contents to include attributes that are specific to our own usecases so it doesn't have to be fixed.

Now, let's have a look at some of the common API operations that can be performed on the SCIM server:

1. Create: This operation provisions new user and makes a record of their identity on the SCIM data store.
2. Read: The read operation fetches user identities from the data store.
3. Update: This make changes to the user identities e.g user changing roles when an employee is promoted.
4. Delete: The delete operation removes existing resource types from the SCIM data store e.g deleting employee records.

How to implement a custom SCIM Server?

Since SCIM is an open standard, it means we can build our own SCIM server customized to suit specific needs. Once the fundamental ingredients as defined in the specification documents are fulfilled, implementing your customized SCIM server is achievable.

Here is a general overview of the steps to implement your custom SCIM:

1. Understand the SCIM standard and RFCs
2. Define your organizational specific requirements identifying which user and group management functionalities you need
3. Select the technology stack to build your own SCIM variant ensuring it supports Restful API and secure communication protocols
4. Design your data model making sure it is in line with SCIM's core resource type which are: Users and Group.
5. Next, implement the core SCIM endpoints based on the specifications.
6. Implement security. Ensure authentication workflow is secured with OAuth or other means and all exchanges are conducted on HTTPS.
7. Develop error handling and logging.
8. Test and proper documentation
9. Deployment, monitoring and scalability

A minor slack in this custom implementation might open up a window for security mishaps. Thus, most efficient developer teams usually opt for outsourcing this crucial part of the piece.

In the following sections, we will talk in more details about using a third party SCIM services and everything you need to know to make the right choice.

How to Evaluate SCIM providers?

What truly makes the difference is a SCIM provider that fulfills your organizational needs to a considerably large extent. Of course, jumping on just about any shiny new product in the market is not advisable.

Therefore, in this part, we shall talk about the important features you need to look out for when weighing and eventually selecting a SCIM provider to go with.

Key features to look for in SCIM providers

1. Compatibility with existing systems: You'll want to look out for a provider that makes it easier to plug into your existing company software without breaking it. This ensures to get SCIM up and running without delays.

2. Ease of integration and deployment: A simplified integration process reduces downtime. This is especially important in a business environment where swift deployment provides a competitive advantage.

3. Security features and compliance : When selecting a SCIM provider, it is essential to ensure they offer robust security features and are compliant with relevant industry standards and regulations such as GDPR and HIPAA Compliance to name a few.

4. Scalability and performance: Consider a SCIM provider that can meet the growing needs of your organization or user base.

5. Customer support and documentation: Timely customer support and well crafted documentation is an indication that the SCIM provider is reliable and ready to assist.

Factors influencing the choice of a SCIM provider

1. Company size and requirements: A small startup would need to provision less user accounts compared to a medium or large enterprise. So, it's important to pick a SCIM provider with a cost effective package.

2. Budget and pricing considerations: The allocated amount a company plans to spend on SCIM resources needs to work with the pricing of the chosen SCIM provider.

3. Specific use cases and industry needs: It's essential to align the features offered by the SCIM provider with your specific industry to know if it can effectively support your organization's identity management requirements.

How to make the right choice?

In conclusion, we have talked about how SCIM simplifies identity management and ensures productivity as well as how SCIM works.

Most importantly, we have discussed things to consider in choosing a SCIM provider along with recommendations based on specific use cases.

Common pitfalls to avoid during selection process

Choosing a SCIM provider can be a weighty decision. Let's look at some common pitalls engineering teams face. 

• Overlooking compliance of SCIM providers: The SCIM protocol is an open standard. This means it states some guidelines and rules for implementing it. Meanwhile, different SCIM providers might translate the guidelines in their own way.

Engineering teams wouldn't want to be in a rush rather should make sure to check that the SCIM provider actually follows the standard.

• Failure to evaluate compatibility: One common mistake developer teams make is not doing a proper analysis on their existing legacy software to determine if it can easily support SCIM integration. This leads to delay in the overall implementation timeline, risk of server errors and cost implications.

• Setting wrong expectations: The SCIM standard is not a one-size-fits-all. Thus, expecting that it will instantly solve all your identity management problems is not the most realistic thing to do. For instance, your IdP (Identity Provider) or SCIM client might not work out of the box with every SCIM service without adding extra customizations here and there. So it's to important to manage expectations.
