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
solutions

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
capabilities and associated interfaces; and an exchange protocol
between products. Where possible the working group may reuse and/or
reference existing data models, like OASIS OpenC2 and other IETF
standards (e.g., NETCONF, RESTCONF, DOTS, I2NSF, etc.) that define
the atomic actions of a course of action playbook.
2. Goals and Deliverables
This working group has the following major goals and deliverables
o CACAO Use Cases and Requirements
* Specify the use cases and requirements
o CACAO Functional Architecture: Roles and Interfaces
* Specify the system functions and roles that are needed to
enable Collaborative Courses of Action
o CACAO Protocol Specification
* Identify and standardize the configuration for at least one
protocol that can be used to distribute course of action
playbooks over the interfaces identified in the CACAO
functional architecture. The WG may choose to use one or more
protocols to address the requirements of both a direct delivery
and publish-subscribe method
o CACAO JSON Data Model
* Create a JSON data model that can capture and enable
collaborative courses of action
o CACAO Interoperability Test Documents
* Define and create a series of tests and documents to assist
with interoperability of the various systems involved.
The working group may decide to not publish the use cases and
requirements; and test documents. That decision will be made during
the lifetime of the working group.
