When using Microsoft Defender for Cloud, what is crucial for integrating security across hybrid environments?

Integrating security across hybrid environments using Microsoft Defender for Cloud requires proper management and oversight of both on-premises and cloud resources. Azure Arc onboarding is crucial for this integration, as it extends Azure services and management capabilities to any infrastructure, whether on-premises, multicloud, or edge.

By utilizing Azure Arc, organizations can bring their on-premises servers and Kubernetes clusters into the Azure management ecosystem, allowing them to apply consistent security policies, monitoring, and compliance assessments across all environments. This consolidation helps ensure a unified security posture and simplifies the administration of security operations, making it easier to manage threats and respond to incidents in a hybrid setup.

Log Analytics workspace deployment, Azure Active Directory integration, and the deployment of Azure policies are important tasks, but they serve different purposes. Log Analytics helps in gathering and analyzing log data, Azure Active Directory is pivotal for identity and access management, and Azure policies are essential for governance and resource compliance. While each of these components plays a role in security, they do not provide the same level of holistic integration across completely different environments that Azure Arc onboarding does.
