Your company's analyst team uses a playbook to make necessary changes to external systems that are integrated with the Google Security Operations…

The most efficient and low-maintenance solution is to use the built-in scheduling capabilities of Google Security Operations SOAR. The Cron Scheduled Connector is specifically designed to generate an event (a case or alert) based on a defined cron schedule. A playbook trigger can then be configured to automatically initiate the existing playbook whenever a case from this specific connector is created. This approach leverages native platform features, requires no custom coding or external infrastructure, and directly reuses the existing playbook, thus minimizing maintenance overhead and maximizing efficiency.

A. Writing a custom job requires duplicating the logic from the existing playbook into a new script. This is inefficient and increases maintenance, as any future changes would need to be made in two places.

C. A user request is a manual action. This option fails to meet the core requirement of automating the task to run at a specific time without human intervention.

D. Using an external VM and a custom script introduces significant overhead. This includes managing the VM's lifecycle, patching, security, and maintaining the script and its API credentials, which is contrary to the requirement for minimal maintenance.

1. Google Cloud Documentation - SOAR Connectors: The "Cron Scheduled Connector" is described as a tool to "generate alerts on a schedule that you define." This is the intended mechanism for creating time-based triggers for automated workflows.

2. Google Cloud Documentation - SOAR Triggers: Triggers are the mechanism to automatically execute a playbook when a new case or alert is created. A trigger can be scoped to a specific rule

such as cases generated by the Cron Scheduled Connector.
