A Cybersecurity Playbook/Workflow Metadata Template for Knowledge Management

This repository presents a standard metadata template to support programmatic knowledge management of security playbooks/orchestration workflows.

The template was first introduced in: Mavroeidis, V., Eis, P., Zadnik, M., Caselli, M., & Jordan, B. (2021, December). On the Integration of Course of Action Playbooks into Shareable Cyber Threat Intelligence. In 2021 IEEE International Conference on Big Data (Big Data) (pp. 2104-2108). IEEE.

An author's version (open access) of the paper is available at: https://arxiv.org/pdf/2110.10540.pdf

This template has been referenced, implemented, and possibly will be enhanced by several Cyber Threat Intelligence sharing and management technologies such as STIX, MISP, and the OASIS Threat Actor Context Ontology (to name a few).

Products that utilize this template or enhanced versions won't be reflected in this repository, meaning that this repository will remain unchanged and will stay here for educational purposes.

Element Description
playbook id A value that uniquely identifies the playbook. This will be a different ID than the one a structured playbook can possibly carry within.
description An explanation, details, and more context about what the playbook does and tries to accomplish.
playbook creation time The time at which the playbook was originally created.
playbook modification time The time at which the playbook was last modified.
revoked A boolean that identifies if the playbook is no longer valid.
playbook creator The entity that created this playbook. It can be, for example, a natural person or an organization. It may be represented using a unique identifier that identifies the creator.
playbook valid from The time from which the playbook is considered valid and the steps that it contains can be executed.
playbook valid until The time at which this playbook should no longer be considered a valid playbook to be executed.
labels A set of labels for the playbook (e.g., adversary persona names, associated groups, or malware family/variant/name that this playbook is related to).
organization type The type of organization that the playbook is intended for. This can be an industry sector.
playbook standard The standard/format/notation the playbook conforms to (e.g., CACAO, BPMN).
playbook abstraction The playbook's level of abstraction (e.g., template, executable).
playbook type The operational roles this playbook addresses (e.g., notification, detection, investigation, prevention, mitigation, remediation, attack).
playbook impact From 0 to 100, an integer representing the impact the playbook has on the organization. A value of 0 means specifically undefined. Impact values range from 1, the lowest impact, to a value of 100, the highest. For example, a purely investigative playbook that is non-invasive could have a low impact value of 1. In contrast, a playbook that performs changes such as adding rules into a firewall should have a higher impact value.
playbook severity From 0 to 100, an integer representing the seriousness of the conditions that this playbook addresses. A value of 0 means specifically undefined. Severity values range from 1, the lowest severity, to a value of 100, the highest.
playbook priority From 0 to 100, an integer representing the priority of this playbook relative to other defined playbooks. A value of 0 means specifically undefined. Priority values range from 1, the highest priority, to a value of 100, the lowest.
playbook The property that will carry the playbook itself. Playbook producers and consumers use this property to share and retrieve playbooks.
