1. Introduction
Interface to Network Security Functions (I2NSF) defines a framework
and interfaces for interacting with Network Security Functions
(NSFs). Note that an NSF is defined as software that provides a set
of security-related services, such as (i) detecting unwanted
activity, (ii) blocking or mitigating the effect of such unwanted
activity in order to fulfill service requirements, and (iii)
supporting communication stream integrity and confidentiality
[i2nsf-terminology].
The I2NSF framework allows heterogeneous NSFs developed by different
security solution vendors to be used in the Network Functions
