Understanding the Requirements :

The objective is to create an incident and generate a report based on malicious attachment events detected by FortiAnalyzer from FortiSandbox analysis.

The endpoint hosts are protected by FortiClient EMS, which is integrated with FortiSandbox. All logs are sent to FortiAnalyzer.

Key Components :

FortiAnalyzer : Centralized logging and analysis for Fortinet devices.

FortiSandbox : Advanced threat protection system that analyzes suspicious files and URLs.

FortiClient EMS : Endpoint management system that integrates with FortiSandbox for endpoint protection.

Playbook Analysis :

The playbook in the exhibit consists of three main actions: GET_EVENTS, RUN_REPORT, and CREATE_INCIDENT.

EVENT_TRIGGER : Starts the playbook when an event occurs.

GET_EVENTS : Fetches relevant events.

RUN_REPORT : Generates a report based on the events.

CREATE_INCIDENT : Creates an incident in the incident management system.

Selecting the Correct Connector :

The correct connector should allow fetching events related to malicious attachments analyzed by FortiSandbox and facilitate integration with FortiAnalyzer.

Connector Options :

FortiSandbox Connector :

Directly integrates with FortiSandbox to fetch analysis results and events related to malicious attachments.

Best suited for getting detailed sandbox analysis results.

Selected as it is directly related to the requirement of handling FortiSandbox analysis events.

FortiClient EMS Connector :

Used for managing endpoint security and integrating with endpoint logs.

Not directly related to fetching sandbox analysis events.

Not selected as it is not directly related to the sandbox analysis events.

FortiMail Connector :

Used for email security and handling email-related logs and events.

Not applicable for sandbox analysis events.

Not selected as it does not relate to the sandbox analysis.

Local Connector :

Handles local events within FortiAnalyzer itself.

Might not be specific enough for fetching detailed sandbox analysis results.

Not selected as it may not provide the required integration with FortiSandbox.

Implementation Steps :

Step 1 : Ensure FortiSandbox is configured to send analysis results to FortiAnalyzer.

Step 2 : Use the FortiSandbox connector in the playbook to fetch events related to malicious attachments.

Step 3 : Configure the GET_EVENTS action to use the FortiSandbox connector.

Step 4 : Set up the RUN_REPORT and CREATE_INCIDENT actions based on the fetched events.
