Document Upload Filter

The Document Upload Filter section looks like this:

Using this section, you can configure actions for outbound user-originating of-

fice documents that are potentially malicious.

The document formats that can be filtered include Microsoft Word 97-2003, Mi-

crosoft Excel 95-2003, Microsoft PowerPoint 95-2003 and all known versions

of Adobe Portable Document Format (PDF).

Furthermore, they include the following open document formats: Generic XML,

Microsoft OpenXML, Oasis Open Document Format, and the Simple Object

Access Protocol (SOAP), which is an XML-based communications protocol for

applications.

These documents may contain “active” content. Word, Excel, PowerPoint and

Microsoft Open XML support ActiveX controls and macros, while PDF and the

Oasis Open Document Format support embedded JavaScript.

This active content may be hostile rather than friendly, so for full protection

against files that are embedded in Microsoft Office, PDF or open format docu-

ments, you should use the filter provided by the Document Inspector to inspect

these documents and block malicious content from entering your corporate net-

work.

If you want to use this filter, make sure the checkbox next to the s ection heading

is marked. The checkbox is marked by default.

After specifying the appropriate settings, click on Apply Changes to make

them effective.

Use the following drop-down list to configure actions for office documents:

• Encrypted document found

Select an action here, e. g. Block or Allow. This action will be taken if the

filter detects an inbound office document that is potentially malicious.
