Setting up SCIM provisioning between CyberArk and IAM Identity Center

IAM Identity Center supports automatic provisioning (synchronization) of user information from CyberArk Directory Platform into IAM Identity Center. This provisioning uses the System for Cross-domain Identity Management (SCIM) v2.0 protocol. For more information, see Using SAML and SCIM identity federation with external identity providers.

You configure this connection in CyberArk using your IAM Identity Center SCIM endpoint and access token. When you configure SCIM synchronization, you create a mapping of your user attributes in CyberArk to the named attributes in IAM Identity Center. This causes the expected attributes to match between IAM Identity Center and CyberArk.

This guide is based on CyberArk as of August 2021. Steps for newer versions may vary. This guide contains a few notes regarding configuration of user authentication through SAML.

Note

Before you begin deploying SCIM, we recommend that you first review the Considerations for using automatic provisioning. Then continue reviewing additional considerations in the next section.

Prerequisites

You will need the following before you can get started:

  • CyberArk subscription or free trial. To sign up for a free trial visit CyberArk.

  • An IAM Identity Center enabled account (free). For more information, see Enable IAM Identity Center.

  • A SAML connection from your CyberArk account to IAM Identity Center, as described in CyberArk documentation for IAM Identity Center.

  • Associate the IAM Identity Center connector with the roles, users and organizations you want to allow access to AWS accounts.

SCIM considerations

The following are considerations when using CyberArk federation for IAM Identity Center:

  • Only roles mapped in the application Provisioning section will be synchronized to IAM Identity Center.

  • The provisioning script is supported only in its default state, once changed the SCIM provisioning might fail.

    • Only one phone number attribute can be synchronized and the default is “work phone”.

  • If the role mapping in CyberArk IAM Identity Center application is changed, the below behavior is expected:

    • If the role names are changed - no changes to the group names in IAM Identity Center.

    • If the group names are changed - new groups will be created in IAM Identity Center, old groups will remain but will have no members.

  • User synchronization and de-provisioning behavior can be set up from the CyberArk IAM Identity Center application, make sure you set up the right behavior for your organization. These are the options you have:

    • Overwrite (or not) users in Identity Center directory with the same principal name.

    • De-provision users from IAM Identity Center when the user is removed from the CyberArk role.

    • De-provision user behavior - disable or delete.

Step 1: Enable provisioning in IAM Identity Center

In this first step, you use the IAM Identity Center console to enable automatic provisioning.

To enable automatic provisioning in IAM Identity Center

  1. After you have completed the prerequisites, open the IAM Identity Center console.

  2. Choose Settings in the left navigation pane.

  3. On the Settings page, locate the Automatic provisioning information box, and then choose Enable. This immediately enables automatic provisioning in IAM Identity Center and displays the necessary SCIM endpoint and access token information.

  4. In the Inbound automatic provisioning dialog box, copy each of the values for the following options. You will need to paste these in later when you configure provisioning in your IdP.

    1. SCIM endpoint - For example, https://scim.us-east-2.amazonaws.com/11111111111-2222-3333-4444-555555555555/scim/v2

    2. Access token - Choose Show token to copy the value.

    Warning

    This is the only time where you can obtain the SCIM endpoint and access token. Ensure you copy these values before moving forward. You will enter these values to configure automatic provisioning in your IdP later in this tutorial.

  5. Choose Close.

Now that you have set up provisioning in the IAM Identity Center console, you need to complete the remaining tasks using the CyberArk IAM Identity Center application. These steps are described in the following procedure.

Step 2: Configure provisioning in CyberArk

Use the following procedure in the CyberArk IAM Identity Center application to enable provisioning with IAM Identity Center. This procedure assumes that you have already added the CyberArk IAM Identity Center application to your CyberArk admin console under Web Apps. If you have not yet done so, refer to the Prerequisites, and then complete this procedure to configure SCIM provisioning.

To configure provisioning in CyberArk

  1. Open the CyberArk IAM Identity Center application that you added as part of configuring SAML for CyberArk (Apps > Web App). See Prerequisites.

  2. Choose the IAM Identity Center application and go to the Provisioning section.

  3. Check the box for Enable provisioning for this application and choose Live Mode.

  4. In the previous procedure, you copied the SCIM endpoint value from IAM Identity Center. Paste that value into the SCIM Service URL field, in the CyberArk IAM Identity Center application set the Authorization Type to be Authorization Header.

  5. Set the Header Type to Bearer Token.

  6. From the previous procedure you copied the Access token value in IAM Identity Center. Paste that value into the Bearer Token field in the CyberArk IAM Identity Center application.

  7. Click Verify to test and apply the configuration.

  8. Under the Sync Options, choose the right behavior for which you want the outbound provisioning from CyberArk to work. You can choose to overwrite (or not) existing IAM Identity Center users with similar principal name, and the de-provisioning behavior.

  9. Under Role Mapping set up the mapping from CyberArk roles, under the Name field to the IAM Identity Center group, under the Destination Group.

  10. Click Save at the bottom once you are done.

  11. To verify that users have been successfully synchronized to IAM Identity Center, return to the IAM Identity Center console and choose Users. Synchronized users from CyberArk will appear on the Users page. These users can now be assigned to accounts and can connect within IAM Identity Center.

(Optional) Step 3: Configure user attributes in CyberArk for access control (ABAC) in IAM Identity Center

This is an optional procedure for CyberArk should you choose to configure attributes for IAM Identity Center to manage access to your AWS resources. The attributes that you define in CyberArk are passed in a SAML assertion to IAM Identity Center. You then create a permission set in IAM Identity Center to manage access based on the attributes you passed from CyberArk.

Before you begin this procedure, you must first enable the Attributes for access control feature. For more information about how to do this, see Enable and configure attributes for access control.

To configure user attributes in CyberArk for access control in IAM Identity Center

  1. Open the CyberArk IAM Identity Center application that you installed as part of configuring SAML for CyberArk (Apps > Web Apps).

  2. Go to the SAML Response option.

  3. Under Attributes, add the relevant attributes to the table following the below logic:

    1. Attribute Name is the original attribute name from CyberArk.

    2. Attribute Value is the attribute name sent in the SAML assertion to IAM Identity Center.

  4. Choose Save.

(Optional) Passing attributes for access control

You can optionally use the Attributes for access control feature in IAM Identity Center to pass an Attribute element with the Name attribute set to https://aws.amazon.com/SAML/Attributes/AccessControl:{TagKey}. This element allows you to pass attributes as session tags in the SAML assertion. For more information about session tags, see Passing session tags in AWS STS in the IAM User Guide.

To pass attributes as session tags, include the AttributeValue element that specifies the value of the tag. For example, to pass the tag key-value pair CostCenter = blue, use the following attribute.

<saml:AttributeStatement>
<saml:Attribute Name="https://aws.amazon.com/SAML/Attributes/AccessControl:CostCenter">
<saml:AttributeValue>blue
</saml:AttributeValue>
</saml:Attribute>
</saml:AttributeStatement>

If you need to add multiple attributes, include a separate Attribute element for each tag.
