Google Cloud Certified - Professional Security Operations Engineer (PSOE) Exam 認定 Security-Operations-Engineer 試験問題 (Q49-Q54):

質問 # 49
Your company's SOC recently responded to a ransomware incident that began with the execution of a malicious document. EDR tools contained the initial infection. However, multiple privileged service accounts continued to exhibit anomalous behavior, including credential dumping and scheduled task creation. You need to design an automated playbook in Google Security Operations (SecOps) SOAR to minimize dwell time and accelerate containment for future similar attacks. Which action should you take in your Google SecOps SOAR playbook to support containment and escalation?

A. Configure a step that revokes OAuth tokens and suspends sessions for high-privilege accounts based on entity risk.
B. Create an external API call to VirusTotal to submit hashes from forensic artifacts.
C. Add an approval step that requires an analyst to validate the alert before executing a containment action.
D. Add a YARA-L rule that sends an alert when a document is executed using a scripting engine such as wscript.exe.

正解：A

解説：
Comprehensive and Detailed Explanation
The correct answer is Option C. The incident description makes it clear that endpoint containment (by EDR) was insufficient, as the attacker successfully pivoted to privileged service accounts and began post- compromise activities (credential dumping, scheduled tasks).
The goal is to automate containment and minimize dwell time.
* Option A is an enrichment/investigation action, not a containment action.
* Option B is the opposite of automation; adding a manual approval step increases dwell time and response time.
* Option D is a detection engineering task (creating a YARA-L rule), not a SOAR playbook (response) action.
Option C is the only true automated containment action that directly addresses the new threat. The anomalous behavior of the privileged accounts would raise their Entity Risk Score within Google SecOps. A modern SOAR playbook can be configured to automatically trigger on this high-risk score and execute an identity- based containment action. Revoking tokens and suspending sessions for the compromised high-privilege accounts is the most effective way to immediately stop the attacker's lateral movement and malicious activity, thereby accelerating containment and minimizing dwell time.
Exact Extract from Google Security Operations Documents:
SOAR Playbooks and Automation: Google Security Operations (SecOps) SOAR enables the orchestration and automation of security responses. Playbooks are designed to execute a series of automated steps to respond to an alert.
Identity and Access Management Integrations: SOAR playbooks can integrate directly with Identity Providers (IdPs) like Google Workspace, Okta, and Microsoft Entra ID. A critical automated containment action for compromised accounts is to revoke active OAuth tokens, suspend user sessions, or disable the account entirely. This action immediately logs the attacker out of all active sessions and prevents them from re-authenticating.
Entity Risk: Detections and anomalous activities contribute to an entity's (e.g., a user or asset) risk score.
Playbooks can be configured to use this risk score as a trigger. For example, if a high-privilege account's risk score crosses a critical threshold, the playbook can automatically execute identity containment actions.

質問 # 50
You are a security engineer at a financial technology company. You need to create a centralized dashboard to provide security posture visibility for your leadership team. The dashboard must meet these requirements:
- Provide insights from Security Command Center (SCC) findings and security-related events captured in Cloud Logging.
- Support large volumes of historical data.
- Be able to join SCC findings and audit logs.
You want to use the most effective visualization solution that uses Google Cloud managed services. What should you do?

A. Use the built-in SCC dashboard to visualize the SCC finding, and extract log counts for specific log events from Cloud Audit Logs.
B. Create custom metrics in Cloud Monitoring based on the SCC findings, and configure log-based metrics for security-related events. Build Cloud Monitoring dashboards to visualize these custom and log-based metrics.
C. Export SCC findings and Cloud Audit Logs to BigQuery. Connect Looker Studio to the BigQuery datasets, and create the visualizations and filters.
D. Ingest the SCC findings and Cloud Audit Logs into a Cloud Storage bucket. Write a Python script that reads the data and uses Matplotlib to create the visualizations.

正解：C

解説：
The most effective approach is to export SCC findings and Cloud Audit Logs into BigQuery, which supports large-scale storage and querying of historical data. You can then connect Looker Studio to BigQuery to create a centralized dashboard that visualizes and joins SCC findings with audit logs. This leverages fully managed Google Cloud services and provides scalability, flexibility, and real-time reporting for leadership visibility.

質問 # 51
Your organization plans to ingest logs from an on-premises MySQL database as a new log source into its Google Security Operations (SecOps) instance. You need to create a solution that minimizes effort. What should you do?

A. Configure and deploy a Bindplane collection agent.
B. Configure and deploy a Google SecOps forwarder.
C. Configure a third-party API feed in Google SecOps.
D. Configure direct ingestion from your Google Cloud organization.

正解：B

解説：
To ingest logs from an on-premises source like MySQL into Google Security Operations (SecOps), you need a secure and supported way to forward those logs to the cloud. The recommended method is to deploy a Google SecOps forwarder on-premises. The forwarder collects logs from local sources (databases, syslog, etc.) and securely sends them to SecOps.

質問 # 52
Your organization has mission-critical production Compute Engine VMS that you monitor daily.
While performing a UDM search in Google Security Operations (SecOps), you discover several outbound network connections from one of the production VMs to an unfamiliar external IP address occurring over the last 48 hours. You need to use Google SecOps to quickly gather more context and assess the reputation of the external IP address. What should you do?

A. Perform a UDM search to identify the specific user account that was logged into the production VM when the connections occurred.
B. Examine the Google SecOps Asset view details for the production VM.
C. Search for the external IP address in the Alerts & IOCs page in Google SecOps.
D. Create a new detection rule to alert on future traffic from the external IP address.

正解：C

解説：
The fastest way to gather context and assess the reputation of the unfamiliar external IP is to search for the IP in the Alerts & IOCs page in Google SecOps. This page integrates with Google Threat Intelligence and enrichment data, allowing you to quickly evaluate whether the IP is malicious and see any related alerts or indicators in your environment.

質問 # 53
You are conducting proactive threat hunting in your company's Google Cloud environment. You suspect that an attacker compromised a developer's credentials and is attempting to move laterally from a development Google Kubernetes Engine (GKE) cluster to critical production systems. You need to identify IoCs and prioritize investigative actions by using Google Cloud's security tools before analyzing raw logs in detail.
What should you do next?

A. In the Security Command Center (SCC) console, apply filters for the cluster and analyze the resulting aggregated findings' timeline and details for IoCs. Examine the attack path simulations associated with attack exposure scores to prioritize subsequent actions.
B. Review threat intelligence feeds within Google Security Operations (SecOps), and enrich any anomalies with context on known IoCs, attacker tactics, techniques, and procedures (TTPs), and campaigns.
C. Investigate Virtual Machine (VM) Threat Detection findings in Security Command Center (SCC). Filter for VM Threat Detection findings to target the Compute Engine instances that serve as the nodes for the cluster, and look for malware or rootkits on the nodes.
D. Create a Google SecOps SOAR playbook that automatically isolates any GKE resources exhibiting unusual network connections to production environments and triggers an alert to the incident response team.

正解：A

解説：
Comprehensive and Detailed 150 to 250 words of Explanation From Exact Extract Google Security Operations Engineer documents:
The key requirements are to "proactively hunt," "prioritize investigative actions," and identify "lateral movement" paths before deep log analysis. This is the primary use case for Security Command Center (SCC) Enterprise. SCC aggregates all findings from Google Cloud services and correlates them with assets.
By filtering on the GKE cluster, the analyst can see all associated findings (e.g., from Event Threat Detection) which may contain initial IoCs.
More importantly, SCC's attack path simulation feature is specifically designed to "prioritize investigative actions" by modeling how an attacker could move laterally. It visualizes the chain of exploits-such as a misconfigured GKE service account with excessive permissions, combined with a public-facing service-that an attacker could use to pivot from the development cluster to high-value production systems. Each path is given an attack exposure score, allowing the hunter to immediately focus on the most critical risks.
Option C is too narrow, as it only checks for malware on nodes, not the lateral movement path. Option B is a later step used to enrich IoCs after they are found. Option D is an automated response (SOAR), not a proactive hunting and prioritization step.
(Reference: Google Cloud documentation, "Security Command Center overview"; "Attack path simulation and attack exposure scores")
