Recommendation ITU-T X.1209 describes high level scenarios and supporting capabilities for cybersecurity information sharing and exchange. This Recommendation provides capabilities important for supporting interoperability between applications for the sharing and exchange of cybersecurity information.

Capabilities are described which may be used in scenarios/situations supporting previously independent acting entities to participate in various coordinated efforts, such as the prevention or halting of targeted behaviour or the coordination of analysis and determination efforts.

The goal of the capabilities listed and described is to support more efficient and effective security operations by supporting the interoperable sharing and exchange of information between trusted parties working together to monitor, maintain and generally manage the security of systems and networks.
