Web Interface - Settings - System - Content Scanning

Overview

This section allows sysadmins to enable scanning of incoming files using a remote anti-virus server. MOVEit DMZ will submit incoming files to the anti-virus server using the ICAP protocol. Files that are clean are then passed into the MOVEit DMZ filesystem.

Note: If you are using the AS2 Module to transfer files, be aware that content scanning does not apply to AS2 transfers. Use MOVEit Central to scan AS2 transfers for viruses.

Before you can configure content scanning for incoming files, you must have one of these anti-virus scanners configured on a machine that is accessible to the MOVEit DMZ system:

Sophos ICAP AV scanner
Symantec Scan Engine

For more information on the Content Scanning feature and associated logs and reporting, see the Feature Focus - Content Scanning topic.

Set Content Scanning

A name for the content scanner and the location (Server URL) for the content scanner are required settings. All of the Content Scanning settings apply to all MOVEit DMZ hosts on the system. The settings are described below:

Scan uploads: 'Yes' means content scanning is enabled for the MOVEit DMZ system, for all organizations. 'No' means content scanning is disabled for all organizations on the system.
Name: is a user-defined name for the content scanning activity, such as "AV scan."
Server URL: is the address of the anti-virus (ICAP) server. This address requires the prefix "icap://", for example: icap://scansrv:1344
Server allows "204" responses: the default setting 'Yes' will allow faster scanning, as the "204" response allows the server to return an updated header without body data.
Maximum file size to scan: the default setting of 15 MB (recommended) means that uploaded files that exceed 15 MB in size will not be fully scanned. MOVEit DMZ does not exclude files larger than the size selected, it actually scans up to the size selected on all files. IF no problem is found in the partial scan, the file is alowed into the DMZ filesystem. If you do not want to have a maximum size for file scanning, enter 0 for this option.
Server connection timeout: the default setting of 5 seconds means that if MOVEit DMZ cannot establish a connection with the anti-virus server within 5 seconds, a connection failure occurs. MOVEit DMZ will attempt to connect again until the maximum number of 'Server connection tries' is reached.
Server connection tries: the default setting of 3 means that MOVEit DMZ will try up to 3 times to create the initial connection to the anti-virus server.
Change Content Scanning: after making any entries or changes, click this button to apply the changes.
Test Content Scanning: tests the AV capability by sending a known fake infected file (EICAR.COM) to the ICAP server and ensuring that it is marked as infected. (To avoid problems with other AV packages that may be running on the system, the EICAR is stored encrypted.) Before testing, be sure to save any changes to the settings by clicking the Change Content Scanning button.
The following screen shows an example of the configuration for a Sophos ICAP AV scanner.

Logging

If a file was scanned, file detail pages will display the ICAP server information.

If a file fails the scan, the user who uploaded the file will see an error message at the top of the browser page.

Also, log file entries will report the user-configured name of the ICAP server used during the file upload. File records will also report the self-identification, version, and virus definition tag from the server.

New error code numbers (6100 - 6103) are used to report content scanning errors. This will help when filtering logs. If an upload fails due to content scanning, the corresponding log table records will contain the ICAP server name and, if possible, the name of the virus.

Notifications

Notification macros for content scanning, if enabled, can report the scan results in the following notifications: New File Upload Notification, File Upload Confirmation, File Non-Delivery Receipt, File Upload List Notification, File Upload List Confirmation, File Not Downloaded List, File Delivery Receipt. The standard templates for these notifications do not include the content scanning results. You can add the macros that report the scan results by creating custom notification templates. Custom notifications are set in an organization via Settings | Appearance | Notification | Custom.

Reporting

You can add a Content Scanning report which shows any content scanning violations. An example of a violation is a file that failed an anti-virus check. In this case, the report will show the name of the scanner, the file name, and the name of the virus (if known). If you are logged in as Admin, the report shows violations for your organization. If you are logged in as sysadmin, the report can show multiple organizations.
