Which feature allows for automated responses to specific security events in Azure?

The feature that allows for automated responses to specific security events in Azure is Azure Automation. This service enables users to automate processes through the creation of runbooks, which can execute predefined tasks based on triggers or schedules. For security events, you can configure Azure Automation in conjunction with other services to create workflows that respond automatically when specific conditions are met.

For instance, when an alert is generated as a result of a security incident, Azure Automation can be employed to execute a runbook that might isolate a virtual machine, remediate vulnerabilities, or even send notifications to administrators—all of which streamline security incident response efforts and reduce the time taken to address threats. This capacity to automate responses is essential in enhancing operational efficiency and minimizing the potential impact of security incidents.

Other choices, while relevant to security management in Azure, do not provide the core functionality of automating responses. Azure Activity Log captures activities within the Azure environment but does not facilitate automated actions. Azure Security Alerts provides insights into potential threats, alerting you to issues but does not perform automatic remediation. Azure Resource Health serves to inform you about the health of your resources but does not interact with security events directly for automated responses.
