                  I2NSF NSF Monitoring YANG Data Model
             draft-ietf-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, the potential sign of denial of service attacks, or system
   overload in a timely manner.  This monitoring functionality is based
   on the monitoring information that is generated by NSFs.  Thus, this
   document describes not only an information model for monitoring NSFs
   along with a YANG data diagram, but also the corresponding YANG data
   model for monitoring NSFs.
