Hi Thomas,

I agree with your support for continuing development of Henk's RATS
architecture
document.  Also your suggestion of profiles.

With respect to Network Endpoint Assessment, folks would benefit from
reading
RFC 5209 NEA Overview and Requirements:

https://datatracker.ietf.org/doc/rfc5209/

Which was the requirements document of the IETF NEA WG, who standardized
the TCG-contributed TNC protocol suite 10 years ago.

Cheers,
- Ira
