    JDBC data sources contain database connection credentials. Changes to these configurations
    should be carefully reviewed.

    This could indicate:
    - Legitimate database configuration management
    - Unauthorized database connection configuration

  Identifies deployment and undeployment of JDBC data source configurations in SAP Cloud Integration.
  JDBC data sources contain database connection credentials and configuration that enable
  integration flows to access backend databases.

  Unauthorized JDBC data source manipulation could indicate:
  - Attacker adding rogue database connections for data exfiltration
  - Credential theft by accessing stored database passwords
  - Modification of connection strings to redirect traffic to attacker-controlled systems
