I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments.

The summary of the review is Ready.

From the abstract, This document defines an information model and a YANG data model for the Registration Interface between Security Controller and Developer's Management System (DMS) in the Interface to Network Security Functions (I2NSF) framework to register Network Security Functions (NSF) of the DMS with the Security Controller.  The objective of these information and data models is to support NSF capability registration and query via I2NSF Registration Interface.

The security considerations section complies with the requirements set forth in https://trac.ietf.org/trac/ops/wiki/yang-security-guidelines. I think this document is ready for publication.
