Description
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.

ℹ️ Check
Ensure the SEL-2740S X.509 certificate is properly configured on the SEL-2740S by checking the "Certificates" page on the OTSDN Controller. If the SEL-2740S public keys were not provided by an approved certificate policy or authority, this is a finding.

✔️ Fix
Import a PEM or PFX X.509 Certificate from an approved service provider into the flow controller as the Root CA certificate so the flow controller can use it to generate and commission the SEL-2740S with an accepted chain of trust. To do this log into the flow controller with security administrator privileges and navigate to the Administration page and then to the X.509 page. Select Import and use the certificate type CA Cert.
