Document Download Filter
The Document Download Filter section looks like this:
Using this section, you can configure actions for inbound office documents that
may enter your corporate network from the Web and 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).
These documents may contain “active” content. Microsoft Word, Excel and
PowerPoint support ActiveX controls and macros, while PDF supports embed-
ded JavaScript.
This active content may be hostile rather than friendly, so for full protection
against files that are embedded into Microsoft Office or PDF documents, you
should use the filter provided by the Document Inspector to inspect these doc-
uments and block malicious content from entering your corporate network.
In addition to this filter, you can apply text categorization to these documents.
If you want to use this filter, make sure the checkbox next to the section 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 items to configure actions for office documents:
• Encrypted document found
From the drop-down list provided here, select an action, e. g. Block or
Allow. This action will be taken if the filter detects an inbound office docu-
ment that is potentially malicious.
• Apply Text Categorization
Mark the checkbox provided here, to apply text categorization actions to
inbound office documents.
To view or modify the actions that are currently configured for these actions,
click on the Text Categorization link in the checkbox inscription.
This will take you to the Text Categorizationtab, where you have access
to the corresponding settings.
