Specification for Transfer of OpenC2 Messages via MQTT v1.0 from OpenC2 TC approved as a Committee Specification
"Transfer via MQTT" is ready for testing and implementation
OASIS is pleased to announce that Specification for Transfer of OpenC2 Messages via MQTT Version 1.0 from the OASIS Open Command and Control (OpenC2) TC [1] has been approved as an OASIS Committee 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.
This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation.
