FCSS_SOC_AN-7.4 Fortinet FCSS - Security Operations 7.4 Analyst Free Practice Exam Questions (2025 Updated)

Understanding FortiAnalyzer Fabric Topology:

The FortiAnalyzer Fabric topology is designed to centralize logging and analysis across multiple devices in a network.

It involves a hierarchy where the supervisor node manages and coordinates with other Fabric members.

Analyzing the Options:

Option A:Downstream collectors forwarding logs to Fabric members is not a typical configuration. Instead, logs are usually centralized to the supervisor.

Option B:For effective management and log centralization, logging devices must be registered to the supervisor. This ensures proper log collection and coordination.

Option C:The supervisor does not primarily use an API to store logs, incidents, and events locally. Logs are stored directly in the FortiAnalyzer database.

Option D:For the Fabric topology to function correctly, all Fabric members need to be in analyzer mode. This mode allows them to collect, analyze, and forward logs appropriately within the topology.

Conclusion:

The correct statements regarding the FortiAnalyzer Fabric topology are that logging devices must be registered to the supervisor and that Fabric members must be in analyzer mode.

Understanding Incident Creation in FortiAnalyzer:

FortiAnalyzer allows for the creation of incidents to track and manage security events.

Incidents can be created both automatically and manually based on detected events and predefined rules.

Analyzing the Methods:

Option A:Using a connector action typically involves integrating with other systems or services and is not a direct method for creating incidents on FortiAnalyzer.

Option B:Incidents can be created manually on the Event Monitor page by selecting relevant events and creating incidents from those events.

Option C:While playbooks can automate responses and actions, the direct creation of incidents is usually managed through event handlers or manual processes.

Option D:Custom event handlers can be configured to trigger incident creation based on specific events or conditions, automating the process within FortiAnalyzer.

Conclusion:

The two valid methods for creating an incident on FortiAnalyzer are manually on the Event Monitor page and using a custom event handler.

Understanding Playbook Triggers:

Playbook triggers are the starting points for automated workflows within FortiAnalyzer or FortiSOAR.

These triggers determine how and when a playbook is executed and can pass relevant information (trigger variables) to subsequent tasks within the playbook.

Types of Playbook Triggers:

EVENT Trigger:

Initiates the playbook when a specific event occurs.

The event details can be used as variables in later tasks to customize the response.

Selected as it allows using event details as trigger variables.

INCIDENT Trigger:

Activates the playbook when an incident is created or updated.

The incident details are available as variables in subsequent tasks.

Selected as it enables the use of incident details as trigger variables.

ON SCHEDULE Trigger:

Executes the playbook at specified times or intervals.

Does not inherently use trigger events to pass variables to later tasks.

Not selected as it does not involve passing trigger event details.

ON DEMAND Trigger:

Runs the playbook manually or as required.

Does not automatically include trigger event details for use in later tasks.

Not selected as it does not use trigger events for variables.

Implementation Steps:

Step 1: Define the conditions for the EVENT or INCIDENT trigger in the playbook configuration.

Step 2: Use the details from the trigger event or incident in subsequent tasks to customize actions and responses.

Step 3: Test the playbook to ensure that the trigger variables are correctly passed and utilized.

Conclusion:

EVENT and INCIDENT triggers are specifically designed to initiate playbooks based on specific occurrences, allowing the use of trigger details in subsequent tasks.

By using the EVENT and INCIDENT triggers, you can leverage trigger events in later tasks as variables, enabling more dynamic and responsive playbook actions.

Understanding the Custom Event Handler Configuration:

The event handler is set up to generate events based on specific log data.

The goal is to generate events specifically for spam emails detected by FortiMail.

Analyzing the Issue:

The event handler is currently generating events for both spam emails and clean emails.

This indicates that the rule's filtering criteria are not correctly distinguishing between spam and non-spam emails.

Evaluating the Options:

Option A:Selecting the "Anti-Spam Log (spam)" in the Log Type field will ensure that only logs related to spam emails are considered. This is the most straightforward and accurate way to filter for spam emails.

Option B:Typingtype==spamin the Log filter by Text field might help filter the logs, but it is not as direct and reliable as selecting the correct log type.

Option C:Disabling the rule to use the filter in the data selector to create the event does not address the issue of filtering for spam logs specifically.

Option D:Selecting "Within a group, the log field Spam Name (snane) has 2 or more unique values" is not directly relevant to filtering spam logs and could lead to incorrect filtering criteria.

Conclusion:

The correct change to make in the rule is to select "Anti-Spam Log (spam)" in the Log Type field. This ensures that the event handler only generates events for spam emails.

Understanding the Event Handler Configuration:

The event handler is set up to detect specific security incidents, such as spearphishing, based on logs forwarded from other Fortinet products like FortiSandbox.

An event handler includes rules that define the conditions under which an event should be triggered.

Analyzing the Current Configuration:

The current event handler is named "Spearphishing handler" with a rule titled "Spearphishing Rule 1".

The log viewer shows that logs are being forwarded by FortiSandbox but no events are generated by FortiAnalyzer.

Key Components of Event Handling:

Log Type: Determines which type of logs will trigger the event handler.

Data Selector: Specifies the criteria that logs must meet to trigger an event.

Automation Stitch: Optional actions that can be triggered when an event occurs.

Notifications: Defines how alerts are communicated when an event is detected.

Issue Identification:

Since FortiSandbox logs are correctly forwarded but no event is generated, the issue likely lies in the data selector configuration or log type matching.

The data selector must be configured to include logs forwarded by FortiSandbox.

Solution:

B. Configure a FortiSandbox data selector and add it to the event handler:

By configuring a data selector specifically for FortiSandbox logs and adding it to the event handler, FortiAnalyzer can accurately identify and trigger events based on the forwarded logs.

Steps to Implement the Solution:

Step 1: Go to the Event Handler settings in FortiAnalyzer.

Step 2: Add a new data selector that includes criteria matching the logs forwarded by FortiSandbox (e.g., log subtype, malware detection details).

Step 3: Link this data selector to the existing spearphishing event handler.

Step 4: Save the configuration and test to ensure events are now being generated.

Conclusion:

The correct configuration of a FortiSandbox data selector within the event handler ensures that FortiAnalyzer can generate events based on relevant logs.

By configuring a FortiSandbox data selector and adding it to the event handler, FortiAnalyzer will be able to accurately generate events based on the appropriate logs.

Understanding the Issue:

The custom event handler for detecting SMTP reconnaissance activities is generating a large number of events.

This high volume of events is overwhelming the notification system, leading to potential alert fatigue and inefficiency in incident response.

Event Handler Configuration:

Event handlers are configured to trigger alerts based on specific criteria.

The frequency and volume of these alerts can be controlled by adjusting the trigger conditions.

Possible Solutions:

A. Increase the trigger count so that it identifies and reduces the count triggered by a particular group:

By increasing the trigger count, you ensure that the event handler only generates alerts after a higher threshold of activity is detected.

This reduces the number of events generated and helps prevent overwhelming the notification system.

Selected as it effectively manages the volume of generated events.

B. Disable the custom event handler because it is not working as expected:

Disabling the event handler is not a practical solution as it would completely stop monitoring for SMTP reconnaissance activities.

Not selected as it does not address the issue of fine-tuning the event generation.

C. Decrease the time range that the custom event handler covers during the attack:

Reducing the time range might help in some cases, but it could also lead to missing important activities if the attack spans a longer period.

Not selected as it could lead to underreporting of significant events.

D. Increase the log field value so that it looks for more unique field values when it creates the event:

Adjusting the log field value might refine the event criteria, but it does not directly control the volume of alerts.

Not selected as it is not the most effective way to manage event volume.

Implementation Steps:

Step 1: Access the event handler configuration in FortiAnalyzer.

Step 2: Locate the trigger count setting within the custom event handler for SMTP reconnaissance.

Step 3: Increase the trigger count to a higher value that balances alert sensitivity and volume.

Step 4: Save the configuration and monitor the event generation to ensure it aligns with expected levels.

Conclusion:

By increasing the trigger count, you can effectively reduce the number of events generated by the custom event handler, preventing the notification system from being overwhelmed.

By increasing the trigger count in the custom event handler, you can manage the volume of generated events and prevent the notification system from being overwhelmed.

Overview of Automation Stitches:

Automation stitches in FortiAnalyzer are predefined sets of automated actions triggered by specific events. These actions help in automating responses to security incidents, improving efficiency, and reducing the response time.

FortiAnalyzer Connectors:

FortiAnalyzer integrates with various Fortinet products and other third-party solutions through connectors. These connectors facilitate communication and data exchange, enabling centralized management and automation.

Available Connectors for Automation Stitches:

FortiCASB:

FortiCASB is a Cloud Access Security Broker that helps secure SaaS applications. However, it is not typically used for running automation stitches within FortiAnalyzer.

Understanding FortiAnalyzer Data Policy and Disk Utilization:

FortiAnalyzer uses data policies to manage log storage, retention, and disk utilization.

The Data Policy section indicates how long logs are kept for analytics and archive purposes.

The Disk Utilization section specifies the allocated disk space and the proportions used for analytics and archive, as well as when alerts should be triggered based on disk usage.

Analyzing the Provided Exhibit:

Keep Logs for Analytics:60 Days

Keep Logs for Archive:120 Days

Disk Allocation:300 GB (with a maximum of 441 GB available)

Analytics: Archive Ratio:30% : 70%

Alert and Delete When Usage Reaches:90%

Potential Problems Identification:

Disk Space Allocation:The allocated disk space is 300 GB out of a possible 441 GB, which might not be insufficient if the log volume is high, but it is not the primary concern based on the given data.

Analytics-to-Archive Ratio:The ratio of 30% for analytics and 70% for archive is unconventional. Typically, a higher percentage is allocated for analytics since real-time or recent data analysis is often prioritized. A common configuration might be a 70% analytics and 30% archive ratio. The misconfigured ratio can lead to insufficient space for analytics, causing issues with real-time monitoring and analysis.

Retention Periods:While the retention periods could be seen as lengthy, they are not necessarily indicative of a problem without knowing the specific log volume and compliance requirements. The length of these periods can vary based on organizational needs and legal requirements.

Conclusion:

Based on the analysis, the primary issue observed is theanalytics-to-archive ratiobeing misconfigured. This misconfiguration can significantly impact the effectiveness of the FortiAnalyzer in real-time log analysis, potentially leading to delayed threat detection and response.
