Re: [i2rs] Kathleen Moriarty's No Objection on draft-ietf-i2rs-yang-l3-topology-08: (with COMMENT)

["Susan Hares" <[e-mail]>]

Juergen: 

I recognize that dislike insecure communication.  You made a similar comment
during the WG LC and IETF review of
draft-ietf-i2rs-protocol-security-requirements.  However, the
draft-ietf-i2rs-protocol-security-requirements were passed by the I2RS WG
and approved by the IESG for RFC publication and it contains the non-secure
communication.  The mandate from the I2RS WG for this shepherd/co-chair is
clear.  

As the shepherd for the topology drafts, I try to write-up something that
might address Kathleen's Moriarty's concerns about the topology draft's
security issues about privacy and the I2RS ephemeral control plane data
store.   I welcome an open discussion on my ideas
(https://datatracker.ietf.org/doc/draft-hares-i2rs-yang-sec-consider).   The
yang doctor's YANG  security consideration template
(https://trac.ietf.org/trac/ops/wiki/yang-security-guidelines) and the
privacy related RFCs (RFC6973) note that some information is sensitive.
Hopefully, this document extends these guidelines to a new data store. 

Cheerily, 
Sue Hares

For what it is worth, I find the notion that data models may be written for
a specific non-secure transport plain broken. There is hardly any content of
a data model I can think of which is generally suitable for insecure
transports.

Can we please kill this idea of _standardizing_ information that is suitable
to send over non-secure transports? I really do not see how the IETF can
make a claim that a given piece of information is never worth protecting (=
suitable for non-secure transports).

Note that I am fine if in a certain trusted tightly-coupled deployment
information is shipped in whatever way but this is then a property of the
_deployment_ and not a property of the _information_.
