Tutorial: Microsoft Entra SSO integration with CrowdStrike Falcon Platform

  • บทความ

In this tutorial, you'll learn how to integrate CrowdStrike Falcon Platform with Microsoft Entra ID. When you integrate CrowdStrike Falcon Platform with Microsoft Entra ID, you can:

  • Control in Microsoft Entra ID who has access to CrowdStrike Falcon Platform.
  • Enable your users to be automatically signed-in to CrowdStrike Falcon Platform with their Microsoft Entra accounts.
  • Manage your accounts in one central location.

Prerequisites

To get started, you need the following items:

  • A Microsoft Entra subscription. If you don't have a subscription, you can get a free account.
  • A valid CrowdStrike Falcon subscription.
  • Along with Cloud Application Administrator, Application Administrator can also add or manage applications in Microsoft Entra ID. For more information, see Azure built-in roles.

Note

This integration is also available to use from Microsoft Entra US Government Cloud environment. You can find this application in the Microsoft Entra US Government Cloud Application Gallery and configure it in the same way as you do from public cloud.

Scenario description

In this tutorial, you configure and test Microsoft Entra SSO in a test environment.

  • CrowdStrike Falcon Platform supports SP and IDP initiated SSO.

Note

Identifier of this application is a fixed string value so only one instance can be configured in one tenant.

To configure the integration of CrowdStrike Falcon Platform into Microsoft Entra ID, you need to add CrowdStrike Falcon Platform from the gallery to your list of managed SaaS apps.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
  2. Browse to Identity > Applications > Enterprise applications > New application.
  3. In the Add from the gallery section, type CrowdStrike Falcon Platform in the search box.
  4. Select CrowdStrike Falcon Platform from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Alternatively, you can also use the Enterprise App Configuration Wizard. In this wizard, you can add an application to your tenant, add users/groups to the app, assign roles, as well as walk through the SSO configuration as well. Learn more about Microsoft 365 wizards.

To configure single sign-on on CrowdStrike Falcon Platform side, you need to send the App Federation Metadata Url to CrowdStrike Falcon Platform support team. They set this setting to have the SAML SSO connection set properly on both sides.

Create CrowdStrike Falcon Platform test user

In this section, you create a user called Britta Simon in CrowdStrike Falcon Platform. Work with CrowdStrike Falcon Platform support team to add the users in the CrowdStrike Falcon Platform platform. Users must be created and activated before you use single sign-on.

Test SSO

In this section, you test your Microsoft Entra single sign-on configuration with following options.

SP initiated:

  • Click on Test this application, this will redirect to CrowdStrike Falcon Platform Sign-on URL where you can initiate the login flow.

  • Go to CrowdStrike Falcon Platform Sign-on URL directly and initiate the login flow from there.

IDP initiated:

  • Click on Test this application, and you should be automatically signed in to the CrowdStrike Falcon Platform for which you set up the SSO.

You can also use Microsoft My Apps to test the application in any mode. When you click the CrowdStrike Falcon Platform tile in the My Apps, if configured in SP mode you would be redirected to the application sign-on page for initiating the login flow and if configured in IDP mode, you should be automatically signed in to the CrowdStrike Falcon Platform for which you set up the SSO. For more information, see Microsoft Entra My Apps.

Next steps

Once you configure CrowdStrike Falcon Platform you can enforce session control, which protects exfiltration and infiltration of your organization’s sensitive data in real time. Session control extends from Conditional Access. Learn how to enforce session control with Microsoft Defender for Cloud Apps.
