Common
Document Types
The Document Types section looks like this:
Using this section, you can configure which of the filters that are accessible
over the other sections of this tab should be applied to which document for-
mats.
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 XM
L,
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, w hile 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 Doc
ument Inspector to inspect
these documents and block malicious content from entering your corporate net-
work.
By default, all filters are configured to ap
ply to all formats.
After modifying these s ettings, click on Apply Changes to make the modifi-
cation effective.
Note that in order to use the filters for doc
uments in Microsoft Open XML or
Oasis Open Document Format, you need to enable the Archive Handler, see
