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 FunctionsShow full document text
