This Standard specifies the requirements needed to add Application Flow Security to SD-WAN Services.
As such, it is based on the SD-WAN Service Attributes and Service Framework, as specified in MEF 70.1 SD-WAN Service Attributes and Service Framework, where Application Flows are comprehensively defined. This Standard defines Security Policy as a set of parameters, the values of which are agreed between the Subscriber and Service Provider (as part of the SWVC List of Policies Service Attribute) and that specify which Security Functions are to be applied to an Application Flow. It also defines Security Functions that, when enabled, enforce Security Policies on a per-Application 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, or decryption and re-encryption by a Middle-Box Function of a TLS-encrypted Application Flow. The capabilities required to support these Security Functions are also defined: Block List, Allow List, Quarantine List and Security Event Notification (SEN).
