An OASIS Work Product Repository

Members of the OASIS Open Command and Control (OpenC2) Technical Committee use this GitHub repository as part of the TC's chartered work. Contributors must be Members of the TC. Work is governed by the OASIS policies and is not done under typical open source licensing. For more details, see the Contributions and Licensing sections below.

:blue_book: Open Command and Control (OpenC2) Language Specification :blue_book:

This repository supports the OpenC2 TC's work to define the elements of Open Command and Control (OpenC2) language and the mechanisms for extending it.

:twisted_rightwards_arrows: Repository Organization :twisted_rightwards_arrows:

OpenC2 work product repositories are organized a bit differently than typical open source software project repositories:

• The Published (default) branch represents the current, stable, approved version of the work product. If the product hasn't progressed past an OASIS Committee Specification Draft (CSD), this branch is essentially empty
• The Working branch is where all work-in-progress content is captured, and is the place to go for the current working version of this work product

More information about the TC's repository organizing conventions and branching strategy can be found in our Documentation Norms.

:left_speech_bubble: Description :left_speech_bubble:

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. It should be understood that a language such as OpenC2 is necessary but insufficient to enable coordinated cyber responses that occur within cyber relevant time. Other aspects of coordinated cyber response such as sensing, analytics, and selecting appropriate courses of action are beyond the scope of OpenC2.
