User Identification

Enables the User Identification page in the Kiosk UI. Click Edit Settings to open the following popup where you can select which questions the user must answer.

When any field is enabled, a user will be presented with a form, at the start of a session, displaying the field and require input from the user. This information will be included in the session report available in Central Management.

Media Manifest

Media Manifest is a signed file that records all the file results of the content on the scanned media and can be validated by other OPSWAT products such as Client or OPSWAT Media Validation Agent without the need for re-scanning file content.

In Scan mode, the manifest will be copied to the scanned media after the scan completes.

In Transfer - USB mode, the manifest will be copied to the secondary media.

Regardless of operating mode, Media Manifest can only be copied to media that is writeable. If the USB device is read-only the Media Manifest feature will not work. Discs are not currently supported for this feature.

Generate Media Manifest - select this option to generate a Media Manifest.

• Certificate - upload the Public and Private key files used by MetaDefender Core to generate the Media Manifest

Country of Origin

The Country of Origin (COO) engine is utilized to detect Supply Chain Risk issues. The engine scans any executable files to determine the country the binary originated from. Any executable found to be originating from a country in the Forbidden list will be marked as Blocked.

Click the checkbox to enable, then select the Countries you wish to block files from. Use the arrow buttons in the middle to move selected countries between the two lists. Click Submit to save the setting.

Vulnerability

The vulnerability engine determines if there are any known Common Vulnerabilities and Exposures (CVE) associated with a file. Any CVEs detected will cause the file to be marked as Blocked.

• Enable Vulnerability - check this to enable vulnerability detection
• Severity Threshold - configure the minimum severity that will be reported:
  • Low - reports Low, Moderate, Important, and Critical CVEs
  • Moderate - report Moderate, Important, and Critical CVEs
  • Important - report Important and Critical CVEs
  • Critical - only report Critical CVEs

Zero-Day Protection

Zero-Day Protection detects any active content embedded in a file such as macros, hyperlinks, etc... and attempts to reconstruct a file without such potential threat vectors.

In Scan mode, files with active content will be marked as Blocked and detected items will be listed.

In Transfer - USB or Transfer - Vault mode, a copy of the original file without the active content will be created and copied over to the secondary media.

In all operation modes, the original file on the original media will remain un-changed.

To enable Zero-Day Protection, check the Enable Zero-Day Protection checkbox.

Data Loss Prevention

The Data Loss Prevention (DLP) engine can detect Personally Identifiable Information (PII) such as Social Security or Credit Card numbers. If the engine identifies any PII within a file, the file will be marked as Blocked and results will show how the certainty level of detection.

• Enable Personally Identifiable Information Protection - check this to enable PII detection
• Certainty Threshold - configure the minimum certainty that will be reported:
  • Low - report Low, Medium, and High certainty of detection
  • Medium - report Medium and High certainty of detection
  • High - only report High certainty of detection
