Professional Cloud Security Engineer

  • Topic 1 Question 271

    You work for a multinational organization that has systems deployed across multiple cloud providers, including Google Cloud. Your organization maintains an extensive on-premises security information and event management (SIEM) system. New security compliance regulations require that relevant Google Cloud logs be integrated seamlessly with the existing SIEM to provide a unified view of security events. You need to implement a solution that exports Google Cloud logs to your on-premises SIEM by using a push-based, near real-time approach. You must prioritize fault tolerance, security, and auto scaling capabilities. In particular, you must ensure that if a log delivery fails, logs are re-sent. What should you do?

    • Create a Pub/Sub topic for log aggregation. Write a custom Python script on a Cloud Function Leverage the Cloud Logging API to periodically pull logs from Google Cloud and forward the logs to the SIEM. Schedule the Cloud Function to run twice per day.

    • Collect all logs into an organization-level aggregated log sink and send the logs to a Pub/Sub topic. Implement a primary Dataflow pipeline that consumes logs from this Pub/Sub topic and delivers the logs to the SIEM. Implement a secondary Dataflow pipeline that replays failed messages.

    • Deploy a Cloud Logging sink with a filter that routes all logs directly to a syslog endpoint. The endpoint is based on a single Compute Engine hosted on Google Cloud that routes all logs to the on-premises SIEM. Implement a Cloud Function that triggers a retry action in case of failure.

    • Utilize custom firewall rules to allow your SIEM to directly query Google Cloud logs. Implement a Cloud Function that notifies the SIEM of a failed delivery and triggers a retry action.
