I'd like to use this sort of information as machine-readable SCAP XML,
so CHIPSEC output can be fed into current enterprise CM/SIEM solutions.
Then, the question of what format is more of needing SCAP OVAL
definitions for Intel HW/FW assets, and then SCAP ARF-based report
plugin for CHIPSEC.

SCAP isn't needed for security researcher usage of CHIPSEC. BUT IMO,
SCAP would be very useful for system administrator's use of CHIPSEC, but
I'm not sure anyone is asking yet.

Currently, SCAP is not too useful for searching for firmware. Today, if
you want to look for BIOS or UEFI (or EFI 1.x) vulnerabilities in NVD,
it's only via full-text search, and hoping reporting of error happens to
include UEFI. Thus the need for SCAP OVAL definitions. (Then UEFI Forum
could not only report vulnerabilities as PDFs -- hosted on SourceForge's
reliable CDN :-) -- but also as CVEs in the NVD (which has also gone
down like SF, but XML content is mirrored by multiple orgs. CHIPSEC --
or Copernicus, if MITRE is maintaining it -- would be needed to fix
SCAP, as there aren't any other vulnerability reporting tools to
generate the needed ARF reports. Maybe -- I've not studied it closely
yet -- the BIOS profile by DMTF's SMASH-and-DASH team might be helpful
for SCAP OVAL starting point?

I presume Intel could make good marketing use of this improved
enterprise security feature. If/when Linaro ports CHIPSEC to AArch64, I
presume some of the anticipated green Linux server market will also like
to have this feature. :-)

Thanks,
Lee
