The HYCU virtual appliance must obtain its public key certificates from an appropriate certificate policy through an approved service provider.

Rule version HYCU-ND-000500 · STIG v1 · 2026-05-23

Discussion

For user certificates, each organization obtains certificates from an approved, shared service provider, as required by OMB policy. For federal agencies operating a legacy public key infrastructure cross-certified with the Federal Bridge Certification Authority at medium assurance or higher, this Certification Authority will suffice.

Check

Open a new HYCU Web UI browser tab and verify there is no warning prompt before proceeding to the Web UI login page.

If a warning appears in the web browser stating, "Not secure", this is a finding.

Fix

Log in to the HYCU Web UI and generate a CSR within the gear menu and "SSL Certificates" menu.

Submit this CSR to a DOD PKI authority to have a new certificate created.

Note: By default, HYCU is configured with a self-signed certificate, but this can be replaced with a DOD-issued certificate. This certificate can be configured by logging in to the HYCU Web UI, navigating to the gear menu and "SSL Certificates" menu, and importing the DOD-issued certificate.
