This document provides context for the DetNet WG and has guided the
development of WG data plane documents, but does not itself define any
protocol formats or mechanisms.

   This document addresses DetNet-specific security considerations from
   the perspective of both the DetNet component designer and the DetNet
   system-level designer. this document provides an
   association of threats against various use cases by industry, and
   also against the individual service properties as defined in the
   DetNet Use Cases.

   This document also addresses common DetNet security considerations
   related to the IP and MPLS data plane technologies (the first to be
   identified as supported by DetNet), thereby complementing the
   Security Considerations sections of the various DetNet Data Plane
   (and other) DetNet documents.

There was significant discussion on what should be in this document and
if it was sufficient.  In the end, the document was indirectly reviewed
by several in the security directorate, as part of their reviews of the
previously submitted (for publication) data plane document and the
general feeling was that this document was in sufficient maturity to be
submitted for publication/

The document is one of the foundation documents for other DetNet WG
activities. It notably has had contributions from end-user part of the

I have reread this document as it progressed as well as in its final
form.  All significant comments have been addressed. The document is
ready for publication.

While this document has be read/commented on by some in the security
directorate, we certainly expect that it will receive an additional
review as part of normal IESG processing.

yes, see:

I think the document has good support from active contributors.

Some of the informational references are to outdated versions.

No, N/A.

There are no yang models.
