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) Project.

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 set of manual or automated actions
   applicable to a given system or human processes.

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

   COA Project 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.

2.  Introduction

   Threat Actors and Intrusion Sets are constantly 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
   and networks and address and contain problems identified during and
   after an incident response.
