34. You are implementing a detection engineering pipeline in your GCP environment. Your goal is to identify lateral movement activity involving service accounts accessing multiple GKE clusters in a short time span, which deviates from baseline behavior. You want to prioritize these detections based on risk. What is the most effective approach to achieve this using Google Cloud tools?
Use Google SecOps to detect access anomalies using Risk Analytics and prioritize high-risk service account behavior.
Query Cloud Audit Logs in Logs Explorer to find IAM role changes across clusters.
Enable OS Login to restrict SSH-based access between nodes in GKE.
Set up a budget alert in Cloud Billing for unexpected compute costs across clusters.
35. Your SecOps team is building a baseline of user activity by correlating login events across different systems. While evaluating identity-related logs, you observe that user.name appears as an email address in some sources (e.g., alice@example.com) and as a shortname in others (e.g., alice). You want to ensure consistent enrichment and user tracking across your detection pipelines in Google SecOps. Which action should you take to ensure reliable correlation and enrichment of user identity across different log sources?
Normalize usernames during log ingestion using a Cloud Function in Pub/Sub
Apply a log exclusion filter to remove logs with unmatched usernames
Use aliasing fields to map user.name values to a canonical username in enrichment rules
Use Event Threat Detection to automatically correlate usernames from different sources
36. A data science team in your organization needs to read BigQuery tables from a dataset in a different project. The dataset resides in Project A, and the team works within Project B. You want to use IAM best practices to grant read-only access to the tables without granting broader dataset or project permissions. What is the recommended way to grant access?
Grant the roles/bigquery.admin role to the users on Project A
Assign the roles/viewer role at the project level in Project A
Share the dataset using a public link and allow all users to access it
Assign the roles/bigquery.dataViewer role on the dataset to the users or group from Project B
37. A security engineer is tasked with creating a Cloud Monitoring alert for suspicious activity in their Google Cloud organization. The alert should trigger if a user performs more than 50 "delete" operations on Cloud Storage objects within a 5-minute window. Which log-based metric and threshold would best achieve this?
A counter metric on storage.objects.get events with a threshold of 50.
A counter metric on storage.objects.delete events with a threshold of 50.
A distribution metric on storage.objects.list events with a threshold of 50.
A counter metric on storage.buckets.delete events with a threshold of 1.
38. Your company has adopted multiple GCP services, and your team uses Security Command Center to monitor potential threats. However, your CISO wants to move toward a more automated response model for high-confidence detections (e.g., leaked service account keys or public storage buckets) to reduce mean time to respond (MTTR). Which solution most effectively aligns with this goal?
Configure SCC to export high-severity findings to Pub/Sub and trigger Cloud Functions that execute remediation tasks.
Use Google Workspace Admin audit logs to detect unusual document sharing behavior.
Schedule a weekly manual review of SCC findings and notify owners via Google Chat.
Use Cloud Billing alerts to detect usage spikes and infer potential compromises.
39. Your organization is designing an automated response playbook in Google SecOps to handle credential leakage incidents. When a service account's key is found on a public GitHub repository, the team wants to automate containment while avoiding accidental disruption of production workloads. Which step is the most appropriate candidate for automation in the playbook?
Automatically remove IAM roles from all users in the project as a precaution.
Automatically disable the exposed key and notify the security team.
Automatically shut down all Compute Engine instances using the affected service account.
Automatically delete the service account associated with the exposed key.
40. Your security operations team has received an alert about a known C2 domain linked to recent phishing activity. You want to verify if any internal users have connected to this domain and reconcile this with asset activity to understand the blast radius and potential compromise. What is the most effective way to reconcile this external threat intelligence with user and asset activity in your Google Cloud environment?
Review the Web Security Scanner findings in SCC for URLs matching the C2 domain.
Check Cloud Billing reports for unusual egress charges indicating large data transfers.
Query VPC flow logs in BigQuery for connections to the domain and enrich with Cloud Identity data for user attribution.
Enable SCC’s default detectors and wait for automated alerts.
