Data to Protect and Sensitivity:

Messages:
- Sensitivity: Can vary depending on the application. Messages might contain sensitive business data, personal information, financial transactions, or operational data.
- Protection: Confidentiality, integrity, and availability of messages are critical. Encryption in transit and at rest, access control, and data loss prevention measures are important.
Configuration Data:
- Sensitivity: High. Configuration data includes access credentials, security settings, and cluster configurations.
- Protection: Confidentiality and integrity are crucial. Secure storage and access control are necessary.
