Google Cloud Certified - Professional Security Operations Engineer (PSOE) Exam 認定 Security-Operations-Engineer 試験問題 (Q140-Q145):

質問 # 140
During a proactive threat hunting exercise, you discover that a critical production project has an external identity with a highly privileged IAM role. You suspect that this is part of a larger intrusion, and it is unknown how long this identity has had access. All logs are enabled and routed to a centralized organization- level Cloud Logging bucket, and historical logs have been exported to BigQuery datasets.
You need to determine whether any actions were taken by this external identity in your environment.
What should you do?

正解：B

解説：
Comprehensive and Detailed 150 to 250 words of Explanation From Exact Extract Google Security Operations Engineer documents:
To definitively determine "whether any actions were taken" by a specific identity, you must search the audit logs directly for that identity's activity. The scenario specifies two data repositories: a centralized Cloud Logging bucket (for recent/retention-period logs) and BigQuery (for historical logs).
According to Google Cloud Observability and Security Operations documentation, Cloud Audit Logs (specifically Admin Activity and Data Access logs) capture "Who did what, where, and when." The primary identifier for the actor in these logs is the protoPayload.authenticationInfo.principalEmail.
Option C is the only method that directly queries the activity logs for the specific actor.
* Cloud Logging: You would use the Logging Query Language to filter: protoPayload.authenticationInfo.
principalEmail="[IDENTITY_EMAIL]".
* BigQuery: You would use SQL to query the exported tables: SELECT * FROM [DATASET.TABLE] WHERE protopayload_auditlog.authenticationInfo.principalEmail = "[IDENTITY_EMAIL]".
Options A and B focus on access potential (Recommender/Policy Analyzer) rather than historical actions.
Option D (VPC Flow Logs) records network traffic 5-tuples and does not contain identity information (principal email), making it unsuitable for attributing API actions to a specific user.

質問 # 141
A Google Security Operations (SecOps) detection rule is generating frequent false positive alerts.
The rule was designed to detect suspicious Cloud Storage enumeration by triggering an alert whenever the storage.objects.list API operation is called using the api.operation UDM field.
However, a legitimate backup automation tool that uses the same API, causing the rule to fire unnecessarily. You need to reduce these false positives from this trusted backup tool while still detecting potentially malicious usage. How should you modify the rule to improve its accuracy?

正解：C

解説：
The most accurate way to reduce false positives is to exclude the known trusted backup automation account by adding a condition such as principal.user.email != "backup- bot@foobaa.com". This keeps the rule active for all other accounts, ensuring you still detect suspicious or malicious Cloud Storage enumeration while preventing unnecessary alerts from legitimate automation.


質問 # 142
You are implementing Google Security Operations (SecOps) at your organization. You discover that the current detection rules are too noisy. Due to the high volume of alerts, some true positives might be missed. You want to ingest additional context sources to reduce false positives in your security detections and to improve the overall positive ratio of the alerts. What should you do?

正解：A

解説：
Ingesting high-value asset (HVA) data from the CMDB allows Google SecOps to prioritize alerts based on the sensitivity and criticality of the affected systems. This reduces noise by helping analysts focus on detections involving critical assets, improving the signal-to-noise ratio and ensuring true positives on important systems are not missed.


質問 # 143
You are developing a new detection rule in Google Security Operations (SecOps). You are defining the YARA-L logic that includes complex event, match, and condition sections. You need to develop and test the rule to ensure that the detections are accurate before the rule is migrated to production. You want to minimize impact to production processes. What should you do?

正解：C

解説：
The Google Security Operations (SecOps) platform provides an integrated, zero-impact workflow for developing and testing detections. The standard method is to use the "Test Rule" feature, which is built directly into the Rules Editor.
After the detection engineer has defined the complete YARA-L logic (including events, match, and condition sections), they can click the "Test Rule" button. This function performs a historical search (a retrohunt) against a specified time range of UDM data (e.g., last 24 hours, last 7 days). The platform then returns a list of all events that would have triggered the detection, without creating any live alerts, cases, or impacting production.
This allows the engineer to "ensure that the detections are accurate" by reviewing the historical matches, identifying potential false positives, and refining the rule's logic. This iterative "develop and test" cycle within the editor is the primary method for validating a rule before it is enabled. While UDM search (Option A) is useful for testing the events section logic, it cannot test the full match and condition logic of the rule. Setting a rule to "live but not alerting" (Option D) is a valid, later step, but the "Test Rule" feature is the correct initial development and testing tool.
(Reference: Google Cloud documentation, "Create and manage rules using the Rules Editor"; "Test a rule")


質問 # 144
You received an alert from Container Threat Detection that an added binary has been executed in a business critical workload. You need to investigate and respond to this incident. What should you do? (Choose two.)

正解：C、E

解説：
The correct response involves both notifying the workload owner and following the response playbook to ensure coordinated incident handling, and reviewing the finding while investigating the pod and related resources to understand the attack and determine the appropriate remediation. This approach ensures proper communication, structured incident response, and thorough technical investigation without prematurely deleting or silencing critical evidence.
