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.

Overview of Automation Stitches: Automation stitches in Fortinet solutions enable automated responses to specific events detected within the network. This automation helps in swiftly mitigating threats without manual intervention.

FortiGate Security Profiles:

FortiGate uses security profiles to enforce policies on network traffic. These profiles can include antivirus, web filtering, intrusion prevention, and more.

When a security profile detects a violation or a specific event, it can trigger predefined actions.

Webhook Calls:

FortiGate can be configured to send webhook calls upon detecting specific security events.

A webhook is an HTTP callback triggered by an event, sending data to a specified URL. This allows FortiGate to communicate with other systems, such as FortiAnalyzer.

FortiAnalyzer Integration:

FortiAnalyzer collects logs and events from various Fortinet devices, providing centralized logging and analysis.

Upon receiving a webhook call from FortiGate, FortiAnalyzer can further analyze the event, generate reports, and take automated actions if configured to do so.

Detailed Process:

Step 1: A security profile on FortiGate triggers a violation based on the defined security policies.

Step 2: FortiGate sends a webhook call to FortiAnalyzer with details of the violation.

Step 3: FortiAnalyzer receives the webhook call and logs the event.

Step 4: Depending on the configuration, FortiAnalyzer can execute an automation stitch to respond to the event, such as sending alerts, generating reports, or triggering further actions.

By understanding the interaction between FortiGate and FortiAnalyzer through webhook calls and automation stitches, security operations can ensure a proactive and efficient response to security events.

Understanding the Playbook and its Components:

The exhibit shows a playbook in which an event trigger starts actions upon detecting a malicious file.

The initial tasks in the playbook include CREATE_INCIDENT and GET_EVENTS.

Analysis of Current Tasks:

EVENT_TRIGGER STARTER: This initiates the playbook when a specified event (malicious file detection) occurs.

CREATE_INCIDENT: This task likely creates a new incident in the incident management system for tracking and response.

GET_EVENTS: This task retrieves the event details related to the detected malicious file.

Objective of the Next Task:

The next logical step after creating an incident and retrieving event details is to update the incident with the event data, ensuring all relevant information is attached to the incident record.

This helps SOC analysts by consolidating all pertinent details within the incident record, facilitating efficient tracking and response.

Evaluating the Options:

Option A: Update Asset and Identity is not directly relevant to attaching event data to the incident.

Option B: Attach Data to Incident sounds plausible but typically, updating an incident involves more comprehensive changes including status updates, adding comments, and other data modifications.

Option C: Run Report is irrelevant in this context as the goal is to update the incident with event data.

Option D: Update Incident is the most suitable action for incorporating event data into the existing incident record.

Conclusion:

The next task in the playbook should be to update the incident with the event data to ensure the incident reflects all necessary information for further investigation and response.

Understanding the Playbook and its Components:

The exhibit shows the status of a playbook named 'DOS attack' and its associated tasks.

The playbook is designed to execute a series of tasks upon detecting a DoS attack event.

Analysis of Playbook Tasks:

Attach_Data_To_Incident: Task ID placeholder_8fab0102, status is 'upstream_failed,' meaning it did not execute properly due to a previous task's failure.

Get Events: Task ID placeholder_fa2a573c, status is 'success.'

Create SMTP Enumeration incident: Task ID placeholder_3db75c0a, status is 'failed.'

Reviewing Raw Logs:

The error log shows a ValueError: invalid literal for int() with base 10: '10.200.200.100'.

This error indicates that the task attempted to convert a string (the IP address '10.200.200.100') to an integer, which is not possible.

Identifying the Source of the Error:

The error occurs in the file 'incident_operator.py,' specifically in the execute method.

This suggests that the task 'Create SMTP Enumeration incident' is the one causing the issue because it failed to process the data type correctly.

Conclusion:

The failure of the playbook is due to the 'Create SMTP Enumeration incident' task receiving a string value (an IP address) when it expects an integer value. This mismatch in data types leads to the error.
