Hello Yoshimura-san and list,
Since the Microsoft SOH is one of two possible ways to carry
attributes (the other being the pure TNC/NEA protocol), it seems like
the IETF or TCG will have to provide
a mapping document to make sure that the two protocols are able to
convey the attributes (and their corresponding datatypes) in an
interoperable fashion. Which means
there may be a "mapping document" like the one the IDS is working on
that will be coming from "somewhere", possibly a separate document, or
an informational appendix
in one of the two transport documents (MS-SOH or NEA )
Also, since the NEA working group did not reach consensus on the HCD
CONFIGURATION STATE attribute, we will need to reserve a place for
this in our own PWG/IDS
extensible attribute list that we should be building. (These will
have to be under the PWG SMI tree)
On the question of version numbers, a vendor can choose whatever
method of version logic is required, just so it fits within the data
types specified. The only operational
requirement is that the "version logic" should allow a device to
UNIQUELY express software module version numbers, and that these
version numbers are UNIQUE-enough
to allow remediation - so the remediation system must understand the
same vendor-specific version logic.
Because of the unique-ness requirement, if you only use the first 16
octets of a version number, then these 16 octets MUST be unique across
all past and future software
releases. At least that's the only way I know to allow robust
remediation.
Best Regards,
Randy
