Abstract

   This document describes the need for defining a standardized language
   and associated protocols to capture and automate a collection of
   coordinated cyber security actions and responses.  This collection of
   actions is called a Course of Action (COA) Playbook.

1.  Definitions

   System: A system is an heterogeneous set of any IT capabilities
   including hardware, software, endpoints (including IoT), networks,
   data centers and platforms with no assumptions on deployment form
   factor (physical, virtual, microservices), deployment scenario,
   geographic distribution, or dispersion.

   COA: A Course of Action is a manual or automated action applicable to
   a given system or human process.

   COA Playbook: A COA Playbook is the instantiation of a sequence of
   COAs that can be executed on a system or set of systems to protect it
   against Cyber threats and attacks.

   COA Playbook Template: A set of high level COA actions defined by an
   organization on how they might respond generically to a specific
   threat scenario without the specific details of the threat included.
   Example: high level steps for mitigating or remediating malware in
   general.

   CACAO: A Collaborative Automated Course of Action Operation
   represents a COA Playbook that can be coordinated and deployed with
   verified responses across a set of heterogeneous cyber security
   systems.

2.  Introduction

   To defend against threat actors and their tactics, techniques, and
   procedures, organizations need to identify, create, and document
   prevention, mitigation, and remediation steps.  These steps when
   grouped together into a course of action (COA) Playbook are used to
   protect systems, networks, data, and users.  The problem is, once
