Second review of this draft specification ends June 15th
OASIS and the OASIS Collaborative Automated Course of Action Operations (CACAO) for Cyber Security TC are pleased to announce that CACAO Security Playbooks v2.0 is now available for public review and comment. This 15-day review is the second public review for Version 2.0 of this specification.
About the specification draft
To defend against threat actors and their tactics, techniques, and procedures, organizations need to identify, create, document, and test detection, investigation, prevention, mitigation, and remediation steps. These steps, when grouped together, form a cyber security playbook that can be used to protect organizational systems, networks, data, and users.
This specification defines the schema and taxonomy for cybersecurity playbooks and how cybersecurity playbooks can be created, documented, and shared in a structured and standardized way across organizational boundaries and technological solutions.
