I separately emailed Martin this same question. He was kind enough to send me a link so sharing here. 

The below link provides an example of using OpenSCAP to consume RedHat data on vulnerabilities in RedHat Linux.

http://www.open-scap.org/page/Documentation#How_to_run_vulnerability_scan_on_Red_Hat_Enterprise_Linux

This may seem terribly obvious to experienced Scappers, but it is only obvious once you see it. I know this because some colleagues some colleagues of mine need to do a "vulnerability scan" for a government client and were looking at Nessus because they thought OpenSCAP was just for checking configuration. It took me a bit, too, to make the connection. 

Looking for more examples and documentation as this would be a useful thread for us newbies...

​To date, I've used OpenSCAP to check the configuration of Unix operating systems against government baselines.

But I assume OpenSCAP can consume any SCAP content including daily CVE feeds? I have not tried that yet. And superficial searching did not reveal any obvious documentation.

Does anyone know of a good example that would get a person started with using OpenSCAP to consume CVE feeds? Any recommendations of freely available feeds?

Thanks!
