When does FortiAnalyzer generate an event?
Correct Answer:
C
Understanding Event Generation in FortiAnalyzer:
FortiAnalyzer generates events based on predefined rules and conditions to help in monitoring and responding to security incidents.
Analyzing the Options:
Option A:Data selectors filter logs based on specific criteria but do not generate events on their own.
Option B:Connectors facilitate integrations with other systems but do not generate events based on log matches.
Option C:Event handlers are configured with rules that define the conditions under which events are generated. When a log matches a rule in an event handler, FortiAnalyzer generates an event.
Option D:Tasks in playbooks execute actions based on predefined workflows but do not directly generate events based on log matches.
Conclusion:
FortiAnalyzer generates an event when a log matches a rule in an event handler.

Which two options describe how the Update Asset and Identity Database playbook is configured? (Choose two.)
Correct Answer:
AD
Understanding the Playbook Configuration:
The playbook named "Update Asset and Identity Database" is designed to update the FortiAnalyzer Asset and Identity database with endpoint and user information.
The exhibit shows the playbook with three main components: ON_SCHEDULE STARTER, GET_ENDPOINTS, and UPDATE_ASSET_AND_IDENTITY.
Analyzing the Components:
ON_SCHEDULE STARTER:This component indicates that the playbook is triggered on a schedule, not on-demand.
GET_ENDPOINTS:This action retrieves information about endpoints, suggesting it interacts with an endpoint management system.
UPDATE_ASSET_AND_IDENTITY:This action updates the FortiAnalyzer Asset and Identity database with the retrieved information.
Evaluating the Options:
Option A:The actions shown in the playbook are standard local actions that can be executed by the FortiAnalyzer, indicating the use of a local connector.
Option B:There is no indication that the playbook uses a FortiMail connector, as the tasks involve endpoint and identity management, not email.
Option C:The playbook is using an "ON_SCHEDULE" trigger, which contradicts the description of an on-demand trigger.
Option D:The action "GET_ENDPOINTS" suggests integration with an endpoint management system, likely FortiClient EMS, which manages endpoints and retrieves information from them.
Conclusion:
The playbook is configured to use a local connector for its actions.
It interacts with FortiClient EMS to get endpoint information and update the FortiAnalyzer Asset and Identity database.

Which FortiAnalyzer connector can you use to run automation stitches9
Correct Answer:
D
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.
Refer to the exhibits.
You configured a spearphishing event handler and the associated rule. However. FortiAnalyzer did not generate an event.
When you check the FortiAnalyzer log viewer, you confirm that FortiSandbox forwarded the appropriate logs, as shown in the raw log exhibit.
What configuration must you change on FortiAnalyzer in order for FortiAnalyzer to generate an event?
Correct Answer:
B
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.

You notice that the custom event handler you configured to detect SMTP reconnaissance activities is creating a large number of events. This is overwhelming your notification system.
How can you fix this?
Correct Answer:
A
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.
