Google Security-Operations-Engineer Google Cloud Certified - Professional Security Operations Engineer (PSOE) Exam Exam Practice Test

Comprehensive and Detailed Explanation

The core task is to evaluate a new tool for fast, low-customization deployment across the entire Google SecOps platform (SIEM and SOAR). This requires checking the two main integration points: data ingestion (SIEM) and automated response (SOAR).

SIEM Ingestion (Option B): To minimize customization for the SIEM, you must verify that Google SecOps can ingest and understand the tool's logs out-of-the-box. This is achieved by checking the Google SecOps documentation for a default parser for that specific tool. If a default parser exists, the logs will be automatically normalized into the Unified Data Model (UDM) upon ingestion, requiring zero custom development.

SOAR Orchestration (Option C): To minimize customization for SOAR, you must verify that pre-built automated actions exist. The Google SecOps Marketplace contains all pre-built SOAR integrations (connectors). By finding the tool in the Marketplace, you can verify which actions (e.g., "Quarantine Host," "Get Process List") are supported, confirming that response playbooks can be built quickly without custom scripting.

Options D and E describe high-effort, custom integration paths, which are the exact opposite of the "minimize customization for faster deployment" requirement.

Exact Extract from Google Security Operations Documents:

Default parsers: Google Security Operations (SecOps) provides a set of default parsers that support many common security products. When logs are ingested from a supported product, SecOps automatically applies the correct parser to normalize the raw log data into the structured Unified Data Model (UDM) format. This is the fastest method to begin ingesting and analyzing new data sources.

Google SecOps Marketplace: The SOAR component of Google SecOps includes a Marketplace that contains a large library of pre-built integrations for common third-party security tools, including EDR, firewalls, and identity providers. Before purchasing a new tool, an engineer should verify its presence in the Marketplace and review the list of supported actions to ensure it meets the organization's automation and orchestration workflow requirements.

Comprehensive and Detailed Explanation

The correct solution is Option A. This scenario requires both data segregation (Requirement 1) and resource sharing (Requirement 2), which is the exact use case for Google SecOps SOAR "Environments."

Google SecOps SOAR (formerly Siemplify) provides a multi-tenancy feature called Environments within a single SOAR tenant. This feature is designed for organizations that need to logically separate data and operations, such as for different business units, geographical regions, or, as in this case, a newly acquired company.

Fulfills Requirement 1 (Data Segregation): Creating a new SOAR environment for Company A ensures that all their ingested alerts and generated cases are isolated within that environment. Analysts assigned only to Company A's environment will not be able to see cases or data from the parent organization's environment.

Fulfills Requirement 2 (Playbook Sharing): Playbooks are managed at the global (tenant) level and can be shared or assigned across multiple environments. This allows Company A's analysts to access and re-purpose the pre-existing playbooks developed by the parent organization, minimizing rework.

Fulfills Requirement 3 (Minimize Effort): This is the built-in, low-effort solution. In contrast, Option D (a second tenant) would be high-effort, costly, and would make sharing playbooks extremely difficult, as tenants are fully isolated. Option B (a new role) controls permissions (e.g., view, edit) but does not inherently segregate data access. Option C (a service account) is for programmatic API access, not for human analysts working in the UI.

Exact Extract from Google Security Operations Documents:

SOAR Environments: Google SecOps SOAR supports multi-tenancy through the use of Environments.6 Environments enable you to maintain data isolation between different logical entities (such as customers, departments, or business units) within the same SOAR instance.7 Each environment functions as a separate workspace, with its own set of cases, alerts, assets, and incident data. This ensures that users and teams operating in one environment cannot access or view data in another, unless they are explicitly granted permission.

Global Resources and Playbooks: While data such as cases is segregated by environment, key SOAR components like playbooks are managed at the global scope. This allows you to create, test, and manage playbooks centrally and then make them available for use across any or all of your environments. This capability enables resource re-use and standardization of response procedures, even in a multi-tenant configuration.

The most direct and efficient method to "quickly gather more context and assess the reputation" of an unknown IP address is to check it against the platform's integrated threat intelligence. The **Alerts & IoCs page**, specifically the **IoC Matches** tab, is the primary interface for this.

Google Security Operations continuously and automatically correlates all ingested UDM (Universal Data Model) events against its vast, integrated threat intelligence feeds, which include data from Google Threat Intelligence (GTI), Mandiant, and VirusTotal. If the unfamiliar external IP address is a known malicious Indicator of Compromise (IoC)—such as a command-and-control (C2) server, malware distribution point, or known scanner—it will have already generated an "IoC Match" finding.

By searching for the IP on this page, an analyst can immediately confirm if it is on a blocklist and gain critical context, such as its threat category, severity, and the specific intelligence source that flagged it. While Option B (finding the user) and Option C (viewing the asset) are valid subsequent steps for understanding the internal scope of the incident, they do not provide the *external reputation* of the IP. Option D is a *response* action taken only *after* the IP has been assessed as malicious.

To execute a playbook on a fixed schedule (once every day) with minimal maintenance, the standard method in Google SecOps SOAR is to utilize a Scheduled Connector (often referred to as a Cron Connector or "Simulate Alert" mechanism).

According to Google Security Operations SOAR documentation, playbooks are primarily triggered by alerts/cases. To run a playbook without an external security event, you must generate a synthetic alert on a schedule. The Cron connector allows you to "configure a schedule (using Cron syntax) to ingest a dummy alert."

You then configure a Playbook Trigger to match this specific dummy alert. When the connector fires at the scheduled time, it creates a case, which matches the trigger, and executes the playbook containing the necessary actions.

This solution is more efficient than Option A (Custom Job) or Option D (External Script) because it utilizes native "No-Code" configuration features, avoids managing external infrastructure, and keeps the logic within the visible Playbook visual editor rather than hidden in IDE code, complying with the "minimizes maintenance overhead" requirement.

The correct answer is A. The most effective and reliable method for a security engineer to "find reliable IoCs and malware behaviors" is to use Google Threat Intelligence (GTI). When a known indicator like a file hash is identified, the primary workflow is threat enrichment. Google Threat Intelligence, which is a core component of the Google SecOps platform and incorporates intelligence from Mandiant and VirusTotal, is the dedicated tool for this. Searching the hash in GTI provides a comprehensive report on the malware variant, including all associated reliable IoCs (e.g., C2 domains, IP addresses, related file hashes) and malware behaviors (TTPs, attribution, and context). This directly fulfills the user's need.

In contrast, Option D (UDM search) is the subsequent step. A UDM search is used to hunt for indicators within your own organization's logs. An engineer would first use GTI to gather the full list of IoCs and behaviors, and then use UDM search to hunt for all of those indicators across their environment. Option B (Web Search) is unreliable for professional operations, and Option C (manual analysis) is too slow for a "common malware variant" and the need to act "quickly."

(Reference: Google Cloud documentation, "Google Threat Intelligence overview"; "Investigating threats using Google Threat Intelligence"; "View IOCs using Applied Threat Intelligence")

Comprehensive and Detailed Explanation

The correct answer is Option C. The question asks for the immediate action to remediate the existing compliance drift, which is the VM that already has an external IP address.

Option C (Remediate): Reconfiguring the VM's network interface to remove the external IP directly fixes the identified misconfiguration. This action brings the resource back into compliance, which will cause the Security Command Center finding to be automatically set to INACTIVE on its next scan.2

Option A (Prevent): Applying the organization policy constraints/compute.vmExternalIpAccess is a preventative control.3 It will stop new VMs from being created with external IPs, but it is not retroactive and does not remove the external IP from the already existing VM. Therefore, it does not remediate the current finding.

Option B (Mask): Removing the tag simply hides the resource from the posture scan. This is a violation of compliance auditing; it masks the problem instead of fixing it.

Option D (Ignore): Marking a finding as fixed without actually fixing the underlying issue is incorrect and will not resolve the compliance drift. The finding will reappear as ACTIVE on the next scan.

Exact Extract from Google Security Operations Documents:

Finding deactivation after remediation: After you remediate a vulnerability or misconfiguration finding, the Security Command Center service that detected the finding automatically sets the state of the finding to INACTIVE the next time the detection service scans for the finding.4 How long Security Command Center takes to set a remediated finding to INACTIVE depends on the schedule of the scan that detects the findin5g.

Organization policy constraints: If enforced, the constraint constraints/compute.vmExternalIpAccess will deny the creation or update of VM instances with IPv4 external IP addresses.6 This constraint is not retroactive and will not restrict the usage of external IPs on existing VM instances. To remediate an existing VM, you must modify the instance's network interface settings and remove the external IP.

The most reliable, automated, and low-maintenance solution is to use the native Google Security Operations (SecOps) SOAR capabilities. A playbook block is a reusable, automated workflow that can be attached to other playbooks, such as the standard case closure playbook.

This block would be configured with a conditional action. This action would check a case field (e.g., case.escalation_status == "escalated"). If the condition is true, the playbook automatically proceeds down the "Yes" branch, which would use an integration action (like "Send Email" for Gmail or Outlook) to send the case details to the director. After the email action, it would proceed to the "Close Case" action. If the condition is false (the case was not escalated), the playbook would proceed down the "No" branch, which would skip the email step and immediately close the case.

This method ensures the process is "reliably sent" and "automatic," as it's built directly into the case management logic. Options C and D are incorrect because they rely on manual analyst actions, which are not reliable and violate the "automatic" requirement. Option A is a custom, external solution that adds unnecessary complexity and maintenance overhead compared to the native SOAR playbook functionality.

(Reference: Google Cloud documentation, "Google SecOps SOAR Playbooks overview"; "Playbook blocks"; "Using conditional logic in playbooks")

Comprehensive and Detailed Explanation

The correct configuration is Option A. This answer addresses two key requirements from the question: the identity mechanism (Cloud Identity) and the required permission level (read-only access including detection rules).

Identity Mechanism (Google Group vs. Workforce Pool):

The prompt explicitly states the organization uses Cloud Identity as its identity provider (IdP). When Cloud Identity or Google Workspace is the IdP, the standard practice is to manage access using Google Groups. Users are added to a group, and IAM roles are granted to that group. Workforce identity federation (which uses workforce pools) is the mechanism used when integrating with a third-party IdP, such as Okta or Azure AD. Since the IdP is Cloud Identity, creating a Google Group is the correct approach. This eliminates options C and D.

Permission Level (roles/chronicle.viewer vs. roles/chronicle.limitedViewer):

The prompt requires "read-only access to all resources, including detection engine rules." The predefined Google SecOps IAM roles are specific about this distinction:

roles/chronicle.viewer (Chronicle API Viewer): Provides "Read-only access to Google SecOps application and API resources." This role includes permissions to view detection rules and retrohunts.

roles/chronicle.limitedViewer (Chronicle API Limited Viewer): Provides "Grants read-only access to Google SecOps application and API resources, excluding detection engine rules and retrohunts."

Therefore, roles/chronicle.limitedViewer (Option B) is incorrect because it excludes access to detection engine rules, which violates the prompt's requirement. The correct role is roles/chronicle.viewer (Option A), as it grants the necessary comprehensive read-only access.

"8The following example grants the Chronicle API Viewer role to to a specific group:"

gcloud projects add-iam-policy-binding PROJECT_ID \

--role roles/chronicle.viewer \

--member "group:GROUP_EMAIL"

The correct, low-impact solution for augmenting a Google-managed parser is to use a parser extension. The problem states that the base parser is still working, but needs to be supplemented to map two new fields.

Copying the entire parser (Option A) is a high-impact, high-maintenance solution ("Customer Specific Parser"). This action makes the organization responsible for all future updates and breaks the link to Google's managed updates, which is not a minimal-impact solution.

The intended, modern solution is the parser extension. This feature allows an engineer to write a small, targeted snippet of Code-Based Normalization (CBN) code that executes after the Google-managed base parser. This extension code can access the raw_log and perform the specific logic needed to extract the two unmapped fields and assign them to their proper Universal Data Model (UDM) fields.

This approach is the fastest to deploy and minimizes change management impact because the core parser remains managed and updated by Google, while the extension simply adds the custom logic on top. Option B, "Extract Additional Fields," is a UI-driven feature, but the underlying mechanism that saves and deploys this logic is the parser extension. Option D is the more precise description of the technical solution.

The key requirement is to hunt for unknown C2 nodes. This implies that the indicators will not exist in any current threat intelligence feed. Therefore, Option C is incorrect as it only hunts for known IoCs. Option A is also incorrect as Security Health Analytics (SHA) is a posture management tool, not a threat hunting tool.

Option D describes a classic and effective hypothesis-driven threat hunt. Attackers frequently use Newly Registered Domains (NRDs) for their C2 infrastructure, as these domains have no established reputation and are not yet on blocklists.

Google Security Operations (SecOps) allows an engineer to write a YARA-L rule that joins real-time event data (UDM network traffic) with contextual data (the entity graph or a custom lookup). An engineer can ingest WHOIS data or a feed of NRDs as context. The YARA-L rule would then compare outbound network connections against this context, looking for any communication with domains registered within the last 30-90 days. By executing this rule as a retrohunt, the engineer can scan all historical data to "generate a list of potential matches" for this high-risk, anomalous behavior, which is a strong indicator of unknown C2 activity.

Comprehensive and Detailed Explanation

This scenario describes a common configuration task where authorization is failing despite successful authentication. The problem stems from the fact that Google SecOps uses a dual-authorization model: one for the main platform (SIEM/Chronicle) and a separate one for the SOAR module. The SOC team needs both.

The prompt states admins already have access, which confirms that prerequisite steps like linking the project (Option A) and configuring Workforce Identity Federation (Option B) are already complete. The problem is specific to the new SOC team's group.

Fixing Instance Access (Option D):

The error "not getting authorized to access the instance" refers to the primary Google Cloud-level authorization. Access to the Google SecOps application itself is controlled by Google Cloud IAM roles on the linked project.1 The SOC team's group, which is federated from the third-party IdP, is represented as a principalSet in IAM. This principalSet must be granted an IAM role to allow sign-in. The roles/chronicle.viewer role is the minimum predefined role required to grant this application access.

Fixing SOAR Access (Option E):

Simply granting the IAM role (Option D) is not enough for the SOC team to perform its job. That role only gets them into the main SIEM interface. The SOAR module (for case management and playbooks) has its own internal role-based access control system. An administrator must also navigate within the SecOps platform to the SOAR Advanced Settings > Users & Groups and grant the SOC team's federated group a SOAR-specific permission, like "Basic" or "Analyst."

Both steps are required to fully "fix the issue" and provide the SOC team with functional access to the platform.

Exact Extract from Google Security Operations Documents:

Identity and Access Management: Access to a Google SecOps instance using a third-party IdP relies on Workforce Identity Federation, but authorization is configured in two distinct locations.

Google Cloud IAM: Authorization to the main SecOps instance (including the SIEM interface) is controlled by Google Cloud IAM.2 The federated identities (groups) from the third-party IdP are mapped to a principalSet. This principalSet must be granted an IAM role on the Google Cloud project linked to the SecOps instance. The roles/chronicle.viewer role is the minimum predefined role required to grant sign-in access.

Google SecOps SOAR: Authorization for the SOAR module (for case management and playbooks) is managed independently.3 An administrator must navigate to the SOAR Advanced Settings > Users & Groups and assign a SOAR-specific role (e.g., 'Basic' or 'Analyst') to the same federated IdP group.

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.

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.

To enforce a specific categorization requirement at the time of case closure, you must customize the Close Case dialog. This feature in Google SecOps SOAR allows administrators to mandate specific fields that analysts must complete before a case can be resolved.

The documentation on Case Management states: "You can customize the Close Case dialog box to require analysts to provide specific information before closing a case... You can add custom fields, such as Root Cause, and define the values that populate the list."

By adding the "five DLP event types" as options in the Root Cause dropdown within the Close Case settings, you ensure that analysts cannot close a DLP case without selecting one of these defined types. Options A, B, and C relate to tagging or naming during the active investigation phase and do not enforce the data entry requirement strictly "when the case is closed" as requested.

The correct solution is to create an Event Threat Detection (ETD) custom module. ETD is the Security Command Center (SCC) service designed to analyze logs for active threats, anomalies, and malicious behavior. The user's requirement is to use a list of known Indicators of Compromise (IoCs) and external signals, which directly aligns with the purpose of ETD.

In contrast, Security Health Analytics (SHA), mentioned in options A and B, is a posture management service. SHA custom modules are used to detect misconfigurations and vulnerabilities in resource settings, not to analyze log streams for threat activity based on IoCs.

Event Threat Detection provides pre-built templates for creating custom modules to simplify the detection engineering process. The "Configurable Bad IP" template is specifically designed for this exact use case. It allows an organization to upload and maintain a list of known malicious IP addresses (a common form of external IoC). ETD will then continuously scan relevant log sources, such as VPC Flow Logs, Cloud DNS logs, and Cloud NAT logs. If any activity to or from an IP address on this custom list is detected, ETD automatically generates a CONFIGURABLE_BAD_IP finding in Security Command Center for review and response. This approach is the native, efficient, and supported method for integrating IP-based IoCs into SCC, unlike option D which requires building a complex, manual pipeline.

(Reference: Google Cloud documentation, "Overview of Event Threat Detection custom modules"; "Using Event Threat Detection custom module templates")

The requirement to detect activity that is *unusual* compared to a *user's established baseline* is the precise definition of **User and Endpoint Behavioral Analytics (UEBA)**. This is a core capability of Google Security Operations Enterprise designed to solve this exact problem with **minimal effort**.

Instead of requiring analysts to write and tune custom rules with static thresholds (like in Option A) or configure external metrics (Option B), the UEBA engine automatically models the behavior of every user and entity. By simply **enabling the curated UEBA detection rulesets**, the platform begins building these dynamic baselines from historical log data.

When a user's activity, such as data download volume, significantly deviates from their *own* normal, established baseline, a UEBA detection (e.g., `Anomalous Data Download`) is automatically generated. These anomalous findings and other risky behaviors are aggregated into a risk score for the user. Analysts can then use the **Risk Analytics dashboard** to proactively identify the highest-risk users and investigate the specific anomalous activities that contributed to their risk score. This built-in, automated approach is far superior and requires less effort than maintaining static, noisy thresholds.

Comprehensive and Detailed Explanation

The correct answers are B and D, as they accurately describe the two primary functions of a modern SecOps platform: SIEM (Detection) and SOAR (Response).

Option B: (Detection Strategy) A SIEM's fundamental purpose is to perform detection. To do this, it must first ingest telemetry (logs) as events. This is the foundational step for any detection and response strategy. Logs from all sources—on-premises (e.g., firewalls, Active Directory) and multi-cloud (e.g., AWS CloudTrail, Azure Activity Logs)—are ingested into Google SecOps, normalized into the Unified Data Model (UDM), and stored as events. This is what allows detection rules to run. (Option C is incorrect as logs are events, not entities).

Option D: (Response Strategy) A SOAR's fundamental purpose is to orchestrate and automate the response to a detection. A key part of this response is event enrichment (or more specifically, observable enrichment). When an alert is ingested by the SOAR, a playbook runs. This playbook uses integrations (e.g., with Mandiant or VirusTotal, which are part of GTI) to query for real-time context on the observables (IPs, hashes, domains) in the alert. This enrichment helps an analyst make a decision or allows the playbook to automate a containment action.

Option A is incorrect because GTI is ingested as context (in the entity graph and Fusion Feed), not as events. Option E is incorrect because "entity enrichment" (e.g., adding user data from AD) happens at the SIEM ingestion level, whereas SOAR integrations perform on-demand enrichment for alerts/events.

Exact Extract from Google Security Operations Documents:

Google SecOps data ingestion: Google Security Operations ingests customer logs, normalizes the data, and detects security alerts. Google SecOps ingests data using... Forwarders, Bindplane agent, Ingestion APIs, Google Cloud. Parsers convert logs from customer systems into a Unified Data Model (UDM) events.

Integrate Mandiant Threat Intelligence with Google SecOps: This document provides guidance on how to integrate Mandiant Threat Intelligence with Google Security Operations (Google SecOps). After you configure an integration instance, you can use it in playbooks.

Actions:

Enrich Entities: Use the Enrich Entities action to enrich entities using the information from Mandiant Threat Intelligence. This action runs on the following Google SecOps entities: Hostname, IP Address, URL, File Hash.

Enrich IOCs: Use this action to enrich indicators of compromise.

This scenario is best addressed using Data Tables (formerly Reference Lists), which allow for dynamic list management with built-in expiration capabilities directly accessible by the Detection Engine.

According to Google Security Operations documentation regarding Data Tables: "Data tables are multicolumn data constructs that let you input your own data into Google Security Operations. They can act as lookup tables with defined columns and the data stored in rows."

The prompt specifically requires handling a restriction period where "Restrictions last five days from the most recent flagging time." Data tables natively support this via Time-to-Live (TTL) settings. The documentation states: "You can specify a Time To Live (TTL) for list entries. When the TTL expires, the entry is automatically removed from the list." Furthermore, "TTL applied at the table level is inherited by the rows. Any update to existing rows resets the TTL for that row," which perfectly automates the maintenance requirement.

To detect the login, you utilize row-based comparisons in YARA-L. The documentation explains the syntax for joining events with tables: "Using an equality operator ( =, != , >, >=, <, <= ) for row-based comparison. For example, $udm_variable.field_path = %data_table_name.column_name." This allows the rule to dynamically check the incoming user against the active "restricted" list without modifying the rule text itself, ensuring the solution is easily maintained.
