Tutorial: Azure AD SSO integration with CrowdStrike Falcon Platform

In this tutorial, you'll learn how to integrate CrowdStrike Falcon Platform with Azure Active Directory (Azure AD). When you integrate CrowdStrike Falcon Platform with Azure AD, you can:

  • Control in Azure AD who has access to CrowdStrike Falcon Platform.
  • Enable your users to be automatically signed-in to CrowdStrike Falcon Platform with their Azure AD accounts.
  • Manage your accounts in one central location - the Azure portal.

Prerequisites

To get started, you need the following items:

  • An Azure AD subscription. If you don't have a subscription, you can get a free account.
  • A valid CrowdStrike Falcon subscription.

Scenario description

In this tutorial, you configure and test Azure AD SSO in a test environment.

  • CrowdStrike Falcon Platform supports SP and IDP initiated SSO.

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

  1. Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
  2. On the left navigation pane, select the Azure Active Directory service.
  3. Navigate to Enterprise Applications and then select All Applications.
  4. To add new application, select New application.
  5. In the Add from the gallery section, type CrowdStrike Falcon Platform in the search box.
  6. Select CrowdStrike Falcon Platform from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Configure and test Azure AD SSO for CrowdStrike Falcon Platform

Configure and test Azure AD SSO with CrowdStrike Falcon Platform using a test user called B.Simon. For SSO to work, you need to establish a link relationship between an Azure AD user and the related user in CrowdStrike Falcon Platform.

To configure and test Azure AD SSO with CrowdStrike Falcon Platform, perform the following steps:

  1. Configure Azure AD SSO - to enable your users to use this feature.
    1. Create an Azure AD test user - to test Azure AD single sign-on with B.Simon.
    2. Assign the Azure AD test user - to enable B.Simon to use Azure AD single sign-on.
  2. Configure CrowdStrike Falcon Platform SSO - to configure the single sign-on settings on application side.
    1. Create CrowdStrike Falcon Platform test user - to have a counterpart of B.Simon in CrowdStrike Falcon Platform that is linked to the Azure AD representation of user.
  3. Test SSO - to verify whether the configuration works.

Configure Azure AD SSO

Follow these steps to enable Azure AD SSO in the Azure portal.

  1. In the Azure portal, on the CrowdStrike Falcon Platform application integration page, find the Manage section and select single sign-on.

  2. On the Select a single sign-on method page, select SAML.

  3. On the Set up single sign-on with SAML page, click the pencil icon for Basic SAML Configuration to edit the settings.

    https://falcon.eu-1.crowdstrike.com/saml/metadata
    https://falcon.laggar.gcw.crowdstrike.com/saml/metadata

    b. In the Reply URL text box, type one of the following URLs:

    Reply URL
    https://falcon.crowdstrike.com/saml/acs
    https://falcon.us-2.crowdstrike.com/saml/acs
    https://falcon.eu-1.crowdstrike.com/saml/acs
    https://falcon.laggar.gcw.crowdstrike.com/saml/acs
  5. Click Set additional URLs and perform the following step if you wish to configure the application in SP initiated mode:

    In the Sign-on URL text box, type one of the following URLs:

    Sign-on URL
    https://falcon.crowdstrike.com/login
    https://falcon.us-2.crowdstrike.com/login
    https://falcon.eu-1.crowdstrike.com/login
    https://falcon.laggar.gcw.crowdstrike.com/login
  6. On the Set up single sign-on with SAML page, In the SAML Signing Certificate section, click copy button to copy App Federation Metadata Url and save it on your computer.

Create an Azure AD test user

In this section, you'll create a test user in the Azure portal called B.Simon.

  1. From the left pane in the Azure portal, select Azure Active Directory, select Users, and then select All users.
  2. Select New user at the top of the screen.
  3. In the User properties, follow these steps:

    3. Select the Show password check box, and then write down the value that's displayed in the Password box.
    4. Click Create.

Assign the Azure AD test user

In this section, you'll enable B.Simon to use Azure single sign-on by granting access to CrowdStrike Falcon Platform.

  1. In the Azure portal, select Enterprise Applications, and then select All applications.
  2. In the applications list, select CrowdStrike Falcon Platform.
  3. In the app's overview page, find the Manage section and select Users and groups.
  4. Select Add user, then select Users and groups in the Add Assignment dialog.
  5. In the Users and groups dialog, select B.Simon from the Users list, then click the Select button at the bottom of the screen.

  7. In the Add Assignment dialog, click the Assign button.

Configure CrowdStrike Falcon Platform SSO

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 Azure AD single sign-on configuration with following options.

SP initiated:

  • Click on Test this application in Azure portal. 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 in Azure portal 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 about the My Apps, see Introduction to the 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 Cloud App Security.
