Overview

Small contractors often use self-hosted OpenVPN or WireGuard for remote access. While the protocols are cryptographically secure, self-managed deployments typically lack the centralized logging, monitoring, configuration management, and audit capabilities required by NIST 800-171.

CUI Risk Assessment

Self-managed VPN deployments rarely meet NIST 800-171 audit, monitoring, and configuration management requirements. No FedRAMP authorization.

Deployment & Architecture

Deployment Model: Self-hosted (open-source)

OpenVPN / WireGuard (Self-hosted) 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

  1. 1ISSO must document current OpenVPN/WireGuard deployment in existing SSP and create POA&M entry for migration within 180 days per DFARS 252.204-7012 requirements.
  2. 2Contracts officer should review all active contracts containing CUI to identify remote access requirements and coordinate with customers on VPN solution changes.
  3. 3IT administrator must export all user certificates, configuration files, and access logs from current OpenVPN/WireGuard deployment for compliance documentation.
  4. 4ISSO shall evaluate FedRAMP-authorized VPN alternatives and document selection rationale in SSP Section 10 (System Environment).
  5. 5System administrator must implement chosen compliant VPN solution with centralized logging configured to meet NIST 800-171 AU-3 requirements.
  6. 6ISSO should update authorization boundary diagram to include new VPN infrastructure and remove legacy self-hosted components.
  7. 7IT staff must configure SIEM integration for new VPN solution to satisfy NIST 800-171 controls 3.3.1 (audit record creation) and 3.3.8 (audit record protection).
  8. 8Security team shall conduct user training on new VPN client installation and multi-factor authentication integration per AC-3 requirements.
  9. 9ISSO must update incident response procedures to include new VPN solution monitoring and log analysis capabilities.
  10. 10System administrator should decommission OpenVPN/WireGuard infrastructure after 30-day parallel operation and user acceptance validation.

Frequently Asked Questions

Is self-hosted OpenVPN compliant for CMMC?

The VPN protocol is secure, but meeting NIST 800-171 requires centralized logging, monitoring, configuration management, and audit trails that self-hosted deployments rarely provide. Consider managed, FedRAMP authorized alternatives.
