I2NSF NSF Monitoring YANG Data Model
draft-ietf-i2nsf-nsf-monitoring-data-model-03
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 an information model for monitoring NSFs
along with a YANG data diagram, but also the corresponding YANG data
model for monitoring NSFs.
