Abstract

This memo extends the Manufacturer Usage Description (MUD) specification to allow manufacturers to define TLS and DTLS profile parameters. This allows a network security service to identify unexpected (D)TLS usage, which can indicate the presence of unauthorized software, malware, or security policy-violating traffic on an endpoint.
