Comprehensive and Detailed Explanation
The correct solution is Option B. The key requirements are "comprehensive monitoring" and "as soon as possible" in a "multi-cloud environment."
Google Security Operations provides Curated Detections, which are out-of-the-box, fully managed rule sets maintained by the Google Cloud Threat Intelligence (GCTI) team. These rules are designed to provide immediate value and broad threat coverage without requiring manual rule writing, tuning, or maintenance.
Within the curated detection library, the Cloud Threats category is the specific rule set designed to detect threats against cloud infrastructure. This category is not limited to Google Cloud; it explicitly includes detections for anomalous behaviors, misconfigurations, and known attack patterns across multi-cloud environments, including AWS and Azure.
Enabling this category is the fastest and most effective way to meet the requirement. Option A (using Gemini) requires manual effort to generate, validate, and test rules. Option C (Applied Threat Intelligence) is a different category that focuses primarily on matching known, high-impact Indicators of Compromise (IOCs) from GCTI, which is less comprehensive than the behavior-based rules in the "Cloud Threats" category. Option D is procedurally incorrect; Customer Care provides support, but detection content is delivered directly within the SecOps platform.
Exact Extract from Google Security Operations Documents:
Google SecOps Curated Detections: Google Security Operations provides access to a library of curated detections that are created and managed by Google Cloud Threat Intelligence (GCTI). These rule sets provide a baseline of threat detection capabilities and are updated continuously.
Curated Detection Categories: Detections are grouped into categories that you can enable based on your organization's needs and data sources. The 'Cloud Threats' category provides broad coverage for threats targeting cloud environments. This rule set includes detections for anomalous activity and common attack techniques across GCP, AWS, and Azure, making it the ideal choice for securing a multi-cloud deployment. Enabling this category allows organizations to start identifying threats immediately.
