This is the charter for the Working Group: Collaborative Automated
Course of Action Operations (CACAO) for Cyber Security
Status of This Memo
This Internet-Draft is submitted in full conformance with the

1. Problem
Threat Actors and Intrusion Sets are advancing at an increasing rate
relative to cyber defense. Further, cyber defenders typically have
to manually identify and process prevention, mitigation, and
remediation steps in order to protect their systems, networks, data,
and users.
Due to this increase and sophistication of cyber attacks the need for
a secure mechanism that would enable system and network operators to
respond to threats in machine relevant time has raised significantly.
While some attacks may be well known to certain security experts and
cyber researchers they are often not documented in a way that would
enable automated mitigation or remediation. A documented language
for describing prevention, mitigation, and remediation actions is
critical for cyber defenders to respond more quickly and reduce the
exposure from an attack.
2. Working Group
To enable and assist cyber defense, the Collaborative Automated
Course of Action Operations (CACAO) for Cyber Security working group
will focus on creating a solution to securely document and share the
actions needed to prevent, mitigate, and remediate threats. This
effort will focus on providing an information model, data
serialization, and transport for defining, sharing, and processing
Collaborative Automated Course of Action Operations (CACAO).
Each collaborative course of action will consist of a sequence of
cyber defense actions that can be coordinated and deployed across a
set of heterogeneous cyber security systems such that both the
actions requested and the resultant outcomes may be monitored and
verified.
The primary focus of this proposed working group will be the
definition and the distribution of the sequence of actions (perhaps
in a tree or graph). Where possible we will leverage existing
efforts that _may_ define the atomic actions to be included in a
process or sequence.

3. Goals
This working group has the following major goals: * Identify and
document the use cases and requirements * Create an information and
data model that can capture and enable collaborative courses of
action (sometimes called playbooks) that can be used to automate some
parts of cyber defense * Identify and document the system functions
and roles that must exist with associated protocols to exchange
information between those system functions * Identify and document
the configuration for a series of protocols that can be used to
distribute courses of action in both direct delivery and publish-
subscribe methods * Define and create a series of tests and documents
to assist with interoperability
4. Deliverables
The working group plans to create informational and standards track
draft documents some of which may be published through the IETF RFC
stream.
Within the first year, the working group aims to: * Identify a
solution for capturing and distributing multiple sequenced atomic
actions, whether they be manual or automated. * Publish a standards
track draft solution that can be used by organizations and vendors to
create and distribute Courses of Action / Playbooks.
