Configure Splunk Enterprise SAML Single Sign-on (SSO)

---

Single Sign-On (SSO) solution by miniOrange provides secure Single Sign-On access into Splunk Enterprise web application for your users using a single set of login credentials with Security Assertion Markup Language (SAML) as an authentication scheme. miniOrange supports many different types of identity providers for logins using SAML for authentication. You can log into Splunk Enterprise using miniOrange credentials or Azure AD credentials or any of your existing identity providers (IdP). With miniOrange SSO services, along with Splunk Enterprise you can also login into other On-Premise and Cloud Applications using your existing Identity Providers/User Store (Azure Active Directory, Okta, Ping) credentials with certificates and encryption . Follow the given SSO setup guide to integrate SAML SSO for your Splunk Enterprise account.

miniOrange and Splunk Enterprise Single Sign-on (SSO) integration supports the following features. You can configure Splunk for either or both types of SSO.

• SP Initiated Single Sign-On (SSO) (for SSO access directly through the Splunk web application)
• IdP Initiated Single Sign-On (SSO) (for SSO access through the miniOrange Identity User Portal)

Follow the Step-by-Step Guide given below for configuring the Splunk Enterprise Platform Single Sign-on (SSO) with SAML 2.0 authentication Scheme

1. Configure Splunk Enterprise in miniOrange

• Login into miniOrange Admin Console.
• Go to Apps and click on Add Application button.



• In Choose Application Type click on SAML/WS-FED application type.



• Search for Splunk Enterprise in the list, if you don't find Splunk Enterprise in the list then, search for custom and you can set up your application via Custom SAML App.

Prerequisites to configure single sign-on for Splunk Platform to authenticate into Idp using SAML as an authentication scheme:

• Before you can configure SAML as an authentication scheme for single sign-on, you must have the following:
• A running Splunk application platform instance that has access to the supported IdP with administrator access. Contact the Splunk Enterprise Support team and request that they enable SAML 2.0 for your account.
• miniOrange or your Active Directory configured to provide the role, realName, and mail attributes for the SSO user.
• The user you use to log into the application platform must hold a role with the

  change_authentication

  capability.
• The Splunk platform instance must be able to contact the SAML IdP over the network.
• Obtain the SP Metadata file from the Splunk application platform:
  1. Log into the Splunk application as an administrator level user. From the systems bar click on Settings > Authentication Methods.
  
  
  
  
  2. For External Authentication Method, select SAML, then click on the link Configure Splunk to use SAML that appears.
  
  
  
  
  3. Click on the SAML Configuration button on the top right corner
  5. The SAML configuration dialog box appears.
  6. Download the SP Metadata File as shown in the below image which you will need further to configure the SAML SSO in miniOrange:
  
  
  
• Go back to your miniOrange Admin Dashboard to configure the SSO for Splunk platform to authenticate using SAML by adding the Splunk application in admin portal as a Service Provider.
• In Basic Settings tab fill the following details:

SP Entity ID or Issuer:	Splunk-[yourSplunkEnterpriseSubdomain] Eg. - If your site is https://xyz.splunkcloud.com/, use Splunk-xyz
ACS URL:	[yourSplunkEnterpriseDomain]/saml/acs Eg. - If your site is https://xyz.splunkcloud.com/, use https://xyz.splunkcloud.com/saml/acs
Audience URI:	mo
Single Logout URL:	[yourSplunkEnterpriseDomain]/saml/logout Eg. - If your site is https://xyz.splunkcloud.com/, use https://xyz.splunkcloud.com/saml/logout
Sign Response:	ON

5. Adaptive Authentication with Splunk Enterprise

A. Restricting access to Splunk Enterprise with IP Blocking

You can use adaptive authentication with Splunk Enterprise Single Sign-On (SSO) to improve the security and functionality of Single Sign-On. You can allow a IP Address in certain range for SSO or you can deny it based your requirements and you can also challenge the user to verify his authenticity. Adaptive authentication manages the user authentication bases on different factors such as Device ID, Location, Time of Access, IP Address and many more.

You can configure Adaptive Authentication with IP Blocking in following way:

• Login to Self Service Console >> Adaptive Authentication.
• Add a Policy Name for your Adaptive Authentication Policy.



• Select your Action for behavior Change and Challenge Type for user from the Action for behavior Change Section.





Action for behavior Change Options :




Attribute	Description
Allow	Allow user to authenticate and use services if Adaptive authentication condition is true.
Challenge	Challenge users with one of the three methods mentioned below for verifying user authenticity.
Deny	Deny user authentications and access to services if Adaptive authentication condition is true.




Challenge Type Options :




Attribute	Description
User second Factor	The User needs to authenticate using the second factor he has opted or assigned for such as OTP over SMS PUSH Notification OTP over Email And 12 more methods.
KBA (Knowledge-based authentication)	The System will ask user for 2 of 3 questions he has configured in his Self Service Console. Only after right answer to both questions user is allowed to proceed further.
OTP over Alternate Email	User will receive a OTP on the alternate email he has configured threw Self Service Console. Once user provides the correct OTP he is allowed to proceed further.



• Now Enable Enable IP Restriction option from the IP RESTRICTION CONFIGURATION section to configure custom IP range.



• Select the Action you want to perform if the IP address is out of the range. i.e. Allow, Challenge & Deny.
• Specify the IP Address range for which you want above setting to reflect. You can add more than one IP Address ranges by clicking on following button +.
• Scroll to the end and click on save.

B. Adaptive Authentication with Limiting number of devices.

Using Adaptive Authentication you can also restrict the number of devices the end user can access the Services on. You can allow end users to access services on a fixed no. of devices. The end users will be able to access services provided by us on this fixed no. of devices.

You can configure Adaptive Authentication with Device Restriction in following way


• Login to Self Service Console >> Adaptive Authentication.
• Add a Policy Name for your Adaptive Authentication Policy.
• Select your Action for behavior Change and Challenge Type for user from the Action for behavior Change Section.




• Scroll down to Device Configuration section and enable Allow User to Register Device option to allow users to register their devices.
• Enter the Number of Devices which are allowed to register in field next to Number of Device Registrations Allowed
• Choose Action if number of devices exceeded (This will override your setting for Action for behavior Change.)
1. Challenge: The user needs to verify himself using any of the three methods mentioned in table in step 5.1
2. Deny : Deny users access to the system
• Enable option Send email alerts to Users if number of Device registrations exceeded allowed count if you want to alert the user about no of devices exceeding the limit. Save the configuration.

C. Add Adaptive Authentication policy to Splunk Enterprise.

• Login to Self Service Console >> Policies.
• Click on Edit option for predefined app policy.



• Set your application name in the Application and select password as Login Method.

• Get email alerts if users login from unknown devices or locations : Admin need to enable this option to enable receiving alerts for different alert options.
  
  
  

Option	Description
Challenge Completed and Device Registered	Enabling this option allows you to send an email alert when an end-user completes a challenge and registers a device.
Challenge Completed but Device Not Registered	Enabling this option allows you to send an email alert when an end-user completes a challenge but do not registers the device.
Challenge Failed	Enabling this option allows you to send an email alert when an end-user fails to complete the challenge.






• Next subsection is Send email alerts which allows us to enable or disable alerts for admin and end-users. To enable alerts for admins, you can enable the “Administrators” switch button.
