OASIS is pleased to announce that Open Command and Control (OpenC2) Architecture Specification Version 1.0 from the OASIS Open Command and Control (OpenC2) TC [1] has been approved as an OASIS Committee Specification.

Cyberattacks are increasingly sophisticated, less expensive to execute, dynamic and automated. The provision of cyber defense via statically configured products operating in isolation is untenable. Standardized interfaces, protocols and data models will facilitate the integration of the functional blocks within a system and between systems. Open Command and Control (OpenC2) is a concise and extensible language to enable machine-to-machine communications for purposes of 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.

The OpenC2 Architecture Specification describes the abstract architecture of OpenC2 to define a common understanding of the messages and interactions for all bindings and serializations.

This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation.

Members of the OpenC2 TC [1] approved this specification by Special Majority Vote. The specification had been released for public review as required by the TC Process [2]. The vote to approve as a Committee Specification with non-material changes passed [3], and the document is now available online in the OASIS Library as referenced above.

Our congratulations to the TC on achieving this milestone and our thanks to the reviewers who provided feedback on the specification drafts to help improve the quality of the work.
