Overview of MIME types

The TightGate-Schleuse allows you to regulate file exchange between TightGate-Pro and workstation PCs. The file transfer is used for this purpose. However, to prevent unregulated file exchange, you can specify at TightGate-Pro which types of files (MIME types) are permitted to be transferred. The following overview shows the available settings for file transfer and the supported MIME types.

Hinweis

A MIME type consists of a media type and a subtype, separated by a slash. For example, text/html or image/jpeg.

Selection methods

The selection methods are not MIME types themselves; they merely serve to make a quick preselection.

SelectionDescription
ALLAll MIME types are selected. The default settings for the special types remain unchanged unpack and no-macros.
NONEAll MIME types are deselected. The default settings for the special types unpack and no-macros.
COPYCopies the selection of MIME types from file download to file upload.

Special types

SelectionDescription
unpackIf unpack is selected, archives are checked individually. The archive file is only passed on to the user if all MIME types present in the archive are permitted. As soon as a MIME type in the archive is not permitted for the user, the process is aborted. The transfer log then shows which MIME type is not permitted. This principle works cumulatively. This means that all MIME types from all transfer groups of which the user ID is a member are permitted, not just the MIME types from the transfer group in which ‘unpack’ is permitted.
Caution: If ‘unpack’ is selected, no archives should be selected as MIME types, as otherwise the content check will fail and the archives will be transferred directly without being checked.
no-macrosIf ‘no-macros’ is selected, all permitted Office documents are checked for the presence of macros. If a macro is detected, the transfer is blocked by the gateway. The check is only carried out on Office 2007 documents (docx, xlsx and pptx) and on all OpenDocument formats.
Caution: The older Windows Office formats (doc, xls and ppt) are not checked

Media types and MIME types

The MIME type consists of a media type and a subtype, separated by a slash. E.g. text/html or image/jpeg. You can select entire media types or individual subtypes.

Media typeDescription
applicationFiles associated with a specific application programme
audioAudio files
imageImages, graphics, photos
messageMessages
textFiles containing ASCII text
videoVideo files

The media type determines the type of data structure, i.e. whether the data is stored in binary or ASCII format. The subtype refers to file formats that are tied to a specific programme or must be executed using special programmes or plug-ins. Subtypes beginning with “x-” are files that are executed on a server.
