Microsoft Sentinel uses automated workflows to respond to security threats quickly and consistently. Playbooks are collections of procedures built on Azure Logic Apps that run when a security event occurs. Security teams use automation rules to define the specific criteria that automatically trigger these playbooks, though analysts can also run them manually on-demand. When an event triggers a playbook, the workflow uses dynamic content from the alert to orchestrate response tasks, enrich data, and send notifications to external systems.
Building a playbook starts by navigating to the automation section of the Sentinel workspace. Creators define triggers based on alerts, incidents, or entities to start the workflow. Within the Logic App, dynamic content allows subsequent actions to use data generated by earlier steps, ensuring a real-time, context-aware response. Error handling must also be configured to guarantee that the workflow completes successfully or fails gracefully even when encountering unexpected issues.
To interact with secure resources, playbooks must authenticate using an identity that has the appropriate permissions. The choice of identity depends on the security requirements of the environment:
To manage and execute these automated workflows, administrators must assign specific roles to users and service accounts. The Microsoft Sentinel Contributor role provides broad management capabilities across the workspace, while the Microsoft Sentinel Responder role allows users to perform incident handling. To run playbooks manually on incidents, an account must be assigned the Microsoft Sentinel Automation Contributor role along with its standard user permissions. Linking playbooks directly to your analytics rules ensures that these authorized configurations execute automatically as soon as a threat is detected.

Playbooks are collections of procedures built on Azure Logic Apps that run when a security event occurs, while automation rules define the specific criteria that automatically trigger these playbooks. Analysts can also run playbooks manually on-demand, but automation rules are the trigger conditions that initiate the automated workflows.
Managed identity is the recommended option for security and ease of integration because it provides secure, token-based access without managing credentials. Service principal is useful when detailed, granular control over permissions is required for accessing Azure resources.
