Final answer:
The defender for Cloud initiatives is defined in Azure Policy. Azure Policy helps enforce compliance with organizational standards and regulations in Azure.
Step-by-step explanation:
The defender for Cloud initiatives is defined in Azure Policy. Azure Policy is a service in Microsoft Azure that enables you to create, assign, and manage policies to enforce compliance within your Azure environment. It helps you keep your cloud resources compliant with organizational standards and regulations.
While Secure Score is a security analytics tool that gives you insights into your organization's security posture across Azure services, it does not specifically define the defender for Cloud initiatives.
Workbooks in Azure Monitor provide a flexible way to create, view, and share visualizations and reports using data from your Azure resources. They can be used to analyze events, metrics, and logs to gain insights into the security of your Cloud initiatives, but they do not define the defender for Cloud initiatives.
Similarly, Compliance Logs record information related to compliance activities and events but do not define the defender for Cloud initiatives.
