1. Introduction
Interface to Network Security Functions (I2NSF) defined a framework
and interfaces for interacting with Network Security Functions
(NSFs). The I2NSF framework allows heterogeneous NSFs developed by
different security solution vendors to be used in the NFV environment
by utilizing the capabilities of such products and the virtualization
of security functions in the NFV platform. In the I2NSF framework,
each NSF initially registers the profile of its own capabilities into
the system in order for themselves to be available in the system. In
