   A YANG Data Model for Monitoring I2NSF Network Security Functions
             draft-hong-i2nsf-nsf-monitoring-data-model-06

Abstract

   This document proposes an information model and the corresponding
   YANG data model for monitoring Network Security Functions (NSFs) in
   the Interface to Network Security Functions (I2NSF) framework.  If
   the monitoring of NSFs is performed in a comprehensive way, it is
   possible to detect the indication of malicious activity, anomalous
   behavior or the potential sign of denial of service attacks in a
   timely manner.  This monitoring functionality is based on the
   monitoring information that is generated by NSFs.  Thus, this
   document describes not only a YANG data diagram to specify an
   information model for monitoring NSFs, but also the corresponding
   YANG data model for monitoring NSFs.
