Configuring Duo as SAML Provider and Multi Factor Authentication for Splunk Cloud

Applicability

Splunk Cloud

Description

As per Splunk Cloud version 7.1.2, native Multi-Factor Authentication feature is not supported with Splunk Cloud. It is currently only supported with On-Prem environment only.

This article aims to assist with general guidance on setting Duo Access Gateway with Splunk Cloud. Links to Duo's official guides are provided as references.

Investigation

Firstly, to avoid confusion, the following community post mentions internal documents of SPL-154283:
https://community.splunk.com/t5/Security/Does-Splunk-Cloud-support-DUO-two-factor-authentication/m-p/253258

However, the guidance is that in SPL-154283 the ability to set MFA settings with Duo/RSA is phased out and results in the statement on this docs:

Splunk Cloud Platform does not support multifactor authentication with Duo Security.

In addition to that, this related documentation on Duo's website "Two-Factor Authentication for Splunk Enterprise" is also not supported for Splunk Cloud. https://duo.com/docs/splunk

Splunk Cloud does not support Duo MFA.

Finally, the steps outlined in aforementioned guides are neither applicable nor supportable in Splunk Cloud.

Resolution

Duo Access Gateway can be utilized as SAML Identity Provider, and MFA can be achieved with Duo Prompt.

Please find Duo's guide "Duo Protection for Splunk SSO with Duo Access Gateway" to configure SAML SSO with Splunk Cloud below:
