Deployment & Architecture
Deployment Model: Cloud SaaS (vendor-hosted)
Cisco Duo (Commercial) has no FedRAMP authorization on record. DFARS 252.204-7012(b)(2)(ii)(D) requires an external cloud service provider to meet security requirements equivalent to the FedRAMP Moderate baseline — an authorization is the straightforward way to show that, but it is not the only one. Without one, the burden is on you to establish, document, and defend equivalency, and to meet the clause's incident-reporting and media-preservation obligations. Most contractors find an authorized alternative cheaper than carrying that burden.
Migration Checklist
- 1ISSO must document current Duo Commercial deployment scope and identify all CUI systems protected by commercial MFA in the authorization boundary diagram.
- 2Contracts officer must verify DFARS 252.204-7012 flowdown requirements are included in Duo Federal procurement and ensure vendor provides FedRAMP authorization documentation.
- 3ISSO must update System Security Plan to remove Duo Commercial from authorization boundary and add risk acceptance documentation for continued commercial use if migration delayed.
- 4System administrator must inventory all enrolled devices and users in Duo Commercial, documenting any device certificates or tokens that contain CUI-derived authentication metadata.
- 5ISSO must create POA&M entry for Duo Commercial non-compliance with target completion date and interim compensating controls including enhanced logging and monitoring.
- 6System administrator must configure parallel Duo Federal environment ensuring all authentication policies match current commercial configuration to prevent CUI access disruptions.
- 7ISSO must validate Duo Federal operates within FedRAMP boundary and update boundary documentation to reflect compliant MFA infrastructure protecting CUI systems.
- 8System administrator must execute migration cutover during planned maintenance window with rollback procedures documented and tested for CUI system availability.
- 9ISSO must verify POA&M closure criteria are met including removal of commercial infrastructure and confirmation of FedRAMP authorization status.
- 10Legal counsel must review contracts for potential DFARS compliance violations related to commercial Duo usage and document remediation timeline for customer notification.
