RE: Question on security document
Folks,
I
agree that this is in many respects an editorial issue, but it is one with
profound capability
for
creating severe technical discrepancies which will delay the creation of
interoperable
implementations. We must not only resolve the
technical content (which we are near
to
doing), but document it in such a manner that people will build it only one way,
the
way we want.

Hi
Folks:
I
hope we do not delay closure on the technical content in order to correct what
seem to be editorial issues.
Charles
Franco,
The problem is that the format of the document does
not differentiate between
the tutorial information and the language that is
to go into the Standard RFCs.
I
would expect that we should have a formal clause for each document
saying
something to the effect:
"and because of the knowledge carried in the above
tutorial, the [FCIP, iSCSI, iFCP]
document should contain the following text to
properly describe the expected
behavior. For the actual standard
requirements, see [FCIP, iSCSI, iFCP]."
This clearly separates the result of the discussion
(text to be shoved into a
Standard RFC which has no authority in this
document, but will have authority when it is
shoved into the Standard RFC, perhaps with
editorial or technical modifications)
and the tutorial discussion itself (which
explains
without any capitalized requirements why it is nice
to do each of the things
proposed in the text to be included in the Standard
RFC).
Bob
We have routinely taken our
text into the security draft, and we had it reviewed and scrubbed off
there by a good group of security experts. We routinely took selected
things back into the authoritative document (iFCP in our case, but it
could have been any one the three protocols). The use of the very same
textual conventions is key to this high-bandwidth interaction, as well as
to keeping the documents in sync as we repeat the cycle over and
over.
The security draft also serves the purpose of keeper of the
knowledge, hence it does not fit the normative text role.
Rationale text and data (e.g., the speed/cycles figures) will hopefully be
a good companion text to many Standard RFC's readers. As well as new RFC
writers (good data outlives bad theory :-).
I don't see a conflict
between MUST words and Informational RFC, the latter clearly and
unambiguously dominates over the former.

Paul,
I rather prefer to
see the security mandates carried in the primary documents, as our
IETF mentors originally proposed. That way, there is less possibility
of inconsistent language that may change the primary documents.
Then the security document would be a tutorial and remain
informational. This will simplify the standardization process,
because each of us will only have to read the security document
for guidelines to our development of the security section of
the primary documents. If we were to make the security
document the standard, then each of us will have to read the
entire document to make sure that some global restriction does not
fall unintentionally on a particular protocol.
If we do
choose to make the security document the authoritative document
(which I would vote against), then it needs a major rewrite to
clarify, separate, and make more precise the requirements for each
protocol.
Charles,
If the security document was
intended as a draft of the security sections for each protocol, it
needs a major rewrite to separate the particular language to be
dropped into each document from the tutorial information. It
then needs to formulate much more clearly and formally the language
that will be dropped into the primary documents. That would be
okay with me, but the draft should indicate that the language to be
dropped into the primary documents is only proposed and that the
actual applicable standards information is contained in the primary
document.
