1.  Introduction

   To defend against threat actors and their tactics, techniques, and
   procedures, organizations need to manually identify, create, and
   document prevention, mitigation, and remediation steps.  These steps
   when grouped together into a course of action playbook are used to
   protect systems, networks, data, and users.  The problem is, once
   these steps have been created there is no standardized and structured
   way to document them or easily share them across organizational
   boundaries and technological solutions.

   This working group will create a standard that implements the course
   of action playbook model for cybersecurity operations.  Each
   collaborative course of action, such as recommended prevention,
   mitigation and remediation steps, will consist of a sequence of cyber
   defense actions that can be executed by the various systems that can
   act on those actions.  These courses of actions should be
   referenceable by other cyber threat intelligence that provides
   support for related data such as threat actors, campaigns, intrusion
   sets, malware, attack patterns, and other adversarial techniques,
   tactics, and procedures.

   It is out of scope of the WG to define or recommend actual
   investigation, detection, prevention, mitigation, and remediation
   steps for a given threat.  The working group will not consider how
   shared actions are operationalized on specific systems, except where
   it is necessary for those actions to interact with the playbook
   including the response expected for a specific action or step.

   This solution will specifically enable:

   1.  the creation and documentation of course of action playbooks in a
       structured machine-readable format

   2.  organizations to digitally sign course of action playbooks

   3.  the securely sharing and distribution of course of action
       playbooks across organizational boundaries and technological

   4.  the creation and documentation of processing instructions for
       course of action playbooks in a machine readable format


   This solution will contain at a minimum a data model that can be used
   to specify course of action playbooks; a defined set of functional
