Explanation:
According to the FortiClient EMS 7.2/7.4 Administration Guide (specifically the Quarantine Management and Malware Protection sections), the correct administrative workflow to restore a blocked file and ensure it is no longer flagged as malicious is to use the Quarantine Management feature on the EMS server.
1. Analysis of the Exhibit
Event Type: The exhibit shows an Antivirus Event where a file named testfile.txt was flagged as Malware: EICAR_TEST_FILE.
Location: The file was found in a local user directory (C:\Users\administrator\Desktop\Resources\testfile.txt).
System State: The endpoint is managed by EMS (indicated by the Policy: Default and EMS status icons).
2. Why Option D is the Correct Choice:
Centralized Control: In a managed environment, the administrator uses the EMS console to oversee security incidents. To restore a file that has been quarantined, the administrator must navigate to Quarantine Management > Files.
Allowlist & Restore Action: By selecting the specific blocked file (testfile.txt) and clicking Allowlist & Restore, two things happen simultaneously:
Restoration: EMS sends a command to the FortiClient endpoint to release the file from the local quarantine folder and return it to its original path.
Allowlisting: The file's hash is added to the Allowlist (managed under Quarantine Management > Allowlist), which prevents FortiClient from re-quarantining the file during future real-time or on-demand scans.
Accessibility: This is the documented method to make a file 'accessible on the endpoint' while ensuring it is not immediately re-blocked by the security engine.
3. Why Other Options are Incorrect:
A . Restore access directly using FortiClient: While FortiClient has a local quarantine tab, the 'Release' button is typically greyed out or restricted when the client is managed by EMS to ensure centralized security policy enforcement.
B . Allow the webserver URL in the exclusion list: The exhibit shows an Antivirus/Malware event, not a Web Filter event. The file has already been downloaded to the local disk and is being blocked by the Real-Time Protection engine, so a Web Filter URL exclusion would have no effect on the local file block.
C . Exclude testfile.txt from the malware protection profile: While adding a path exclusion to the Malware Protection profile is a valid way to prevent future scans of a directory, it does not automatically restore a file that has already been moved to quarantine. The proper workflow for an existing block is to use the Quarantine Management tool first.
