This document expands upon the definition and specification of the Secure Access Service Edge (SASE) Service Framework, as specified in MEF 117.
For Service Providers, it has become important to deliver the SASE networking and Security Functions as a cohesive Service that can bring together a wide variety of implementations. This includes Security Functions, Policies and Connectivity Services. The document defines the behaviors of the SASE Service that are externally visible to the Subscriber irrespective of the implementation of the Service. A SASE Service based upon the framework defined in this document enables secure access and secure connectivity of Users, Devices, or Applications to resources for the Subscriber.
This document includes:
SASE Service Attributes – The enumeration and description of the information that is agreed between the Subscriber and the SASE Service Provider. The values of these Service Attributes are determined by agreement between the Subscriber and Service Provider, subject to constraints imposed by the Service Provider’s Service description.
SASE Service Framework – A framework for defining components of a SASE Service based on these Service definitions, Service components, and Service Attributes included in the document.This document supersedes and revises MEF 117 and changes to the standard are summarized in Appendix C.
