Comprehensive and Detailed Explanation:

To ensure all logs (existing and future) are automatically processed by the SIEM system, the best approach is:

Use an organization-level aggregated sink → Captures logs from all existing and future projects automatically.

Send logs to a Pub/Sub topic → Since the SIEM ingests logs via Pub/Sub, this ensures logs are streamed in real-time.

Set an inclusion filter → To capture all logs needed by the security team.

????Why not other options?

B (Project-level logging sink)❌→ Requires manual setup per project, which doesn’t scale for new projects.

C (Log bucket instead of Pub/Sub)❌→ SIEM is expecting real-time log ingestion via Pub/Sub, not a storage-based approach.

D (Folder-level logging sink)❌→ Only applies to specific folders, not the entire organization.
