Which feature in Azure Sentinel is used to automate incident responses?

The feature in Azure Sentinel that automates incident responses is playbooks using Azure Logic Apps. Playbooks allow organizations to define automated workflows that integrate with various services and applications within and outside of Azure. This automation can help streamline responses to security incidents by executing specific actions automatically when certain conditions are met, such as sending notifications, creating tickets, or taking remedial actions.

Using playbooks enhances operational efficiency by reducing the time and effort required to respond to incidents, allowing security teams to focus on more complex issues that require human analysis. The flexibility of Azure Logic Apps allows for customization of these workflows, ensuring that they meet the specific needs of the organization.

In contrast, incident reports serve to document security incidents and their details but do not directly automate responses. Manual approvals involve human intervention to approve actions, which slows down response times and is not considered automation. Security dashboards are valuable for visualization and monitoring security metrics but do not provide automation features for incident management. Thus, playbooks using Azure Logic Apps are the clear solution for automating incident responses in Azure Sentinel.
