This topic provides specific instructions for using Azure AD to authenticate your Cortex XSIAM users. As Azure AD is third-party software, specific procedures and screenshots may change without notice. We encourage you to also review the Azure AD documentation.

To configure SAML SSO in Cortex XSIAM, you must be a user who can access the Cortex XSIAM tenant and have either the Account Admin or Instance Admin role assigned.

Within Azure AD, assign users to security groups that match the user groups they will belong to in Cortex XSIAM. Users can be assigned to multiple Azure AD groups and receive permissions associated with multiple user groups in Cortex XSIAM. Use an identifying word or phrase, such as Cortex XSIAM, within the group names. For example, Cortex XSIAM Analysts. This allows you to send only relevant group information to Cortex XSIAM, based on a filter you will set in the group attribute statement.

  1. In Cortex XSIAM go to SettingsConfigurationsAccess ManagementSingle Sign-On.

  2. In the Login Options tab, toggle SSO Disabled to on.

  3. Expand the SSO Integration settings.

  4. Copy and save the values for Single Sign-On URL and Audience URI (SP Entity ID). Both values are needed to configure your IdP settings.

  5. You can not save the enabled SSO Integration at this time, as it requires values from your IdP.

  1. From within Azure AD, create a Cortex XSIAM application and Edit the Basic SAML Configuration.

  2. Paste the Single sign-on URL and the Audience URI (SP Entity ID) that you copied from the Cortex XSIAM SSO settings. The Single sign-on URL from Cortex XSIAM should be pasted in the Reply URL and the Sign on URL fields . The Audience URI (SP Entity ID) value from Cortex XSIAM should be pasted in the Identifier (Entity ID) and Relay State fields. This allows users to log in to Cortex XSIAM directly from Azure AD.

  3. In the SAML Certificates section, click Edit and verify that Azure is configured to sign both the response and the assertion.

  4. To have Azure AD send group membership for the user in the SAML token, you must + Add a group claim in the Attributes & Claims section. Send the Security groups, using the source attribute Group ID. Use the word or phrase you selected when configuring Azure AD security groups (such as Cortex XSIAM) to create a filter. Customize the name of the group claim as memberOf.
