Publication History

Overview

This page provides the publication history of OpenC2 TC work products, with links to the most recent “approved” version as well as the current work-in-progress for the product. An entry is provided for each work product. For each document the reference includes the full title, a brief descripotions, and a table with the following information for “approved” versions:

  • Version
  • Approval Level -- A link to a specific version of the document. The first row in each table is a link to the current working version on GitHub, reflecting either the latest change to in-progress content, or the starting point for future changes, depending on the document's current development status. Subsequent rows are identified by approval level, which is one of:
    • OASIS Standard (OS) -- an official OASIS publication approved by the OASIS membership (none of the TC’s work products have yet reached this level).
    • Committee Specification (CS) -- an official OASIS publication approved by a special majority vote of the TC as a complete and usable document.
    • Committee Specification Draft (CSD) -- an official OASIS publication approved by a majority vote of the TC, a mostly-stable and usable but unfinished specification.
    • Committee Specification / Public Review Draft (CSPRD) -- an official OASIS publication approved by a majority vote of the TC and specified for release for public review (this terminology only applies to the TC’s original three specifications).
    • Working Draft (WD) -- a snapshot version of a work-in-progress document posted to OASIS by the work product editors NOTE: for OS-, CS-, and CSD-level documents this item will be a link to the published HTML version of the work product; for WD-level documents the public link to the WD package in the TC’s document repository will be used.
  • Publication Date -- the date when this version / approval level document was published. For an OS, CS, or CSD this will be the date contained in the published HTML version of the document. Unapproved WDs will instead have the date the WD package was uploaded to OASIS.

Tables are ordered in reverse chronological order, newest version first.



Open Command and Control (OpenC2) Language Specification

The Language Specification is an overarching OpenC2 document, which defines the basic conventions of the language, the set of available actions, and the base set of targets to which actions can be applied. This 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.

OpenC2 Actuator Profile for Stateless Packet Filtering (SLPF)

OpenC2 Actuator Profiles specify the subset of the OpenC2 language relevant in the context of specific actuator functions. This actuator profile specifies the set of actions, targets, specifiers, and command arguments that integrates Stateless Packet Filtering functionality with the OpenC2 command set.

OpenC2 Actuator Profile for Packet Filtering (PF)

OpenC2 Actuator Profiles specify the subset of the OpenC2 language relevant in the context of specific actuator functions. Packet filtering is a cyber defense mechanism that denies or allows traffic based on static or dynamic properties of the traffic, such as address, port, protocol, etc. This profile defines the Actions, Targets, Specifiers and Options that are consistent with the Version 1.0 of the OpenC2 Language Specification in the context of packet filtering (PF).

Specification for Transfer of OpenC2 Messages via HTTPS

OpenC2 transfer specifications utilize existing protocols and standards to implement OpenC2 in specific environments. This specification describes the use of HTTP over TLS as a transfer mechanism for OpenC2 messages.

Specification for Transfer of OpenC2 Messages via MQTT

OpenC2 transfer specifications utilize existing protocols and standards to implement OpenC2 in specific environments. 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.

Specification for JSON Abstract Data Notation (JADN)

JSON Abstract Data Notation (JADN) is a UML-based information modeling language that defines data structure independently of data format. Information models are used to define and generate physical data models, validate information instances, and enable lossless translation across data formats. A JADN specification consists of two parts: type definitions that comprise the information model, and serialization rules that define how information instances are represented as data. The information model is itself an information instance that can be serialized and transferred between applications. The model is documented using a compact and expressive interface definition language, property tables, or entity relationship diagrams, easing integration with existing design processes and architecture tools.
