Which Azure Arc feature can Hiram use to ensure his Azure VMs conform to security policies?

The feature that Hiram can use to ensure his Azure VMs conform to security policies is Azure Policy. This service is designed specifically to create and manage policies that govern resource properties within Azure to enforce compliance with organizational standards and to assess compliance at various levels.

By employing Azure Policy, Hiram can define rules that check for compliance in resources, automatically remediate non-compliant resources, and ensure that Azure VMs adhere to specific security posture requirements. This is essential for organizations looking to maintain security best practices across their cloud resources. The ability to audit and enforce policies helps in maintaining governance and security while leveraging the flexibility of Azure services.

In contrast, while Azure Monitor provides metrics and logging for tracking resource performance, it doesn’t specifically enforce security policies. Azure Security Center offers a range of security management and threat protection capabilities, but it centers more on assessing and responding to security issues rather than directly enforcing compliance through specified policies. Azure Sentinel serves as a security information and event management (SIEM) solution, focusing on threat detection and response but does not play a direct role in policy enforcement. Thus, Azure Policy stands out as the effective tool for ensuring compliance with security policies on Azure VMs.
