This Standard specifies the requirements needed to add Security Functions to an IP Service.

This document defines the set of parameters that need to be agreed between the Subscriber and Service Provider for each Security Function. It also defines Security Functions that, when enabled, enforce the Policy on a per-Service Flow basis by performing any of the following actions: IP, Port and Protocol Filtering, DNS Protocol Filtering, Domain Name Filtering, URL Filtering, Malware Detection and Removal, Data Loss Prevention, Protective DNS or decryption and re-encryption by a Middlebox Security Function. The capabilities required to support these Security Functions are also defined.

This document will supersede and replace MEF 88, Application Flow Security for SD-WAN Services by generalizing Security Functions to support any type of IP Service, including SD-WAN.
