OASIS Members and other interested parties,
We are pleased to announce that Open Command and Control (OpenC2) Language Specification Version 1.0, Open Command and Control (OpenC2) Profile for Stateless Packet Filtering Version 1.0, and Specification for Transfer of OpenC2 Messages via HTTPS Version 1.0 from the OASIS Open Command and Control (OpenC2) TC [1] is now available for public review and comment. This is the third public review for these titles.
OpenC2 is a suite of specifications to achieve command and control of cyber defense functions. These specifications include the OpenC2 Language Specification, Actuator Profiles, and Transfer Specifications. The OpenC2 Language Specification and Actuator Profile(s) focus on the standard at the producer and consumer of the command and response while the transfer specifications focus on the protocols for their exchange.
- The OpenC2 Language Specification provides the semantics for the essential elements of the language, the structure for commands and responses, and the schema that defines the proper syntax for the language elements that represents the command or response.
- The Profile for Stateless Packet Filtering Version is a cyber defense mechanism that denies or allows traffic based on static properties of the traffic, such as address, port, protocol, etc. This profile defines the Actions, Targets, Specifiers, and Options that are consistent with version 1.0 of the OpenC2 Language Specification.
- The Specification for Transfer of OpenC2 Messages via HTTPS 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. HTTP over TLS is a widely deployed transfer protocol that provides an authenticated, ordered, lossless delivery of uniquely-identified messages. This document specifies the use of HTTP over TLS as a transfer mechanism for OpenC2 Messages.
