Invitation to comment on Specification for Transfer of OpenC2 Messages via MQTT v1.0

First public review of this draft specification - ends September 29th

OASIS and the OASIS Open Command and Control (OpenC2) TC are pleased to announce that Specification for Transfer of OpenC2 Messages via MQTT Version 1.0 is now available for public review and comment. This is the first public review for this specification.

Open Command and Control (OpenC2) is a concise and extensible language to enable the command and control of cyber defense components, subsystems and/or systems in a manner that is agnostic of the underlying products, technologies, transport mechanisms or other aspects of the implementation. Message Queuing Telemetry Transport (MQTT) is a widely-used publish / subscribe (pub/sub) transfer protocol. This specification describes the use of MQTT Version 5.0 as a transfer mechanism for OpenC2 messages.
