You can protect access to Splunk by integrating Splunk with Identity as a Service. Once integrated, users can use single sign-on to log in to their Splunk account through Identity as a Service. note This integration was tested using Identity as a Service version 5.14 and Splunk version 8.1.1. Other versions of Splunk may require integration and configuration steps that differ from those documented in this procedure. For other versions of Splunk, use this procedure as a starting point for integrating Splunk. In the event of other issues, contact for assistance. To integrate Splunk with Identity as a Service, you must do the following ## Step 1: Download the metadata from Splunk 1. Log in to your Splunk account as an administrator. 2. Click **Settings >** **Authentication Methods**. 3. If the Choose **Default Dashboard** dialog box appears, click **Save** and then click **Settings > Authentication Methods** again.

The **Metadata Configuration** dialog box appears. 12. If required, click **Merge with existing values** to merge new values with existing values for Alternative Assertion Consumer Services URLs and SAML attribute names. 13. Click **Save**. attention Note the **Service Provider Entity ID (Issuer)**. You need this in _Step 5: Configure Splunk for Identity as a Service authentication_. 14. Optional. Enter the **SAML Username Parameter Name** used to identity the user ID being requested for authentication. The user ID can then be passed as a parameter, for example, Username=jdoe. Alternately, if the SAML username is NameID, the SAML Request XML NameID element value is used to the identify the IDaaS userID. 15. Enter the **SAML Session Timeout** to the time when the SAML Assertion times out. The maximum is 720 minutes. 16. Enter the **Max Authentication Age (seconds)** to set the maximum amount of time that can elapse before a user is required to reauthenticate during a new login attempt. This applies for both SP-initiated and IDP-initiated login. Set this field to -1 to disable this feature. 17. From the **SAML NameID Attribute** drop-down list, select **UserID**. 18. From the **SAML NameID Encoding Format** drop-down list, select **Unspecified**. 19. From the **SAML Signing Certificate** the drop-down list, select the signing certificate. 20. From the **SAML NameID Encoding Format** drop-down list, select **SHA256**. 21. Deselect **Sign Complete SAML Response**. 22. Deselect **Enable Go Back Button** if you do not want users to be able to go back to the Splunk login page to log in. 23. Select **Show Default Assertion Consumer URL Service in the My Profile**.

Add **Alternative Assertion Consumer Service URLs**, as follows: 1. Click **Add**. 2. Enter a **Name**. 3. Enter a URL **Value**. 4. Select **Show in My Profile** to display the Alternative Consumer Service URL in a user's My profile page. 5. Optional. **Add an Application Logo**. 6. Click **Add**. 7. Repeat these steps to add more Alternative Assertion Consumer Service URLs. 25. Add a **SAML Attribute** for Groups, as follows: 1. Under **SAML Attributes**, click **Add**. The **SAML Attributes** dialog box appears. 2. In the **Name** field, enter SPGroups. attention Note the **Name**. You need this in _Step 5: Configure Splunk for Identity as a Service authentication_. 3. Click **Add** next to **Value(s)**. 4. Type **[** and select **[Groups]** to include a user's groups every time the user authenticates to Splunk. 26. Click **Submit**. ## Step 3: Add a resource rule See [Create resource rules](/docs/authentication-and-security/create-and-manage-resource-rules.md). ## Step 4: Download the metadata file from Identity as a Service 1.
