I2NSF NSF Monitoring YANG Data Model
draft-ietf-i2nsf-nsf-monitoring-data-model-02
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.
Editorial Note (To be removed by RFC Editor)
Please update these statements within the document with the RFC
number to be assigned to this document:
"This version of this YANG module is part of RFC 6087;"
"RFC XXXX: I2NSF NSF Monitoring YANG Data Model"
"reference: RFC 6087"
Please update the "revision" date of the YANG module.
