Overview of MIME types
The TightGate-Schleuse offers the possibility to regulate the file exchange between TightGate-Pro and the workstation PCs. The file transfer is used for this purpose. However, to prevent unregulated file exchange, you can specify which types of files (MIME types) may be transferred at TightGate-Pro. The following overview shows which setting options are available for file transfer and which MIME types can be used.
Hint
The MIME type consists of the specification of a media type and a subtype, separated by a slash. E.g. text/html or image/jpeg.
Selection methods
The selection methods are not MIME types themselves, they are merely used to make a quick preselection.
| Selection | Description |
|---|---|
| ALL | All MIME types are selected. The preallocation for the special types is not changed unpack and no-macros. |
| NONE | All MIME types are deselected. The default setting for the special types is not changed unpack and no-macros. |
| COPY | Copies the selection of MIME types from file download for the file upload. |
Special types
| Selection | Description |
|---|---|
| unpack | If unpack is selected, archives are checked individually. The archive file is only sent to the user if all MIME types in the archive are permitted. As soon as a MIME type in the archive is not permitted for the user, the transfer is cancelled. 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 in which the user ID is a member are permitted and 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-macros | Is no-macros is selected, all permitted Office documents are checked for the presence of macros. If a macro is detected, the transfer is prevented by the lock. The check is only carried out for Office documents of type Office 2007 (docx, xlsx and pptx) and for all OpenDocument formats. Caution: The old Windows Office formats (doc, xls and ppt) are not checked |
Media types and MIME types
The MIME type consists of the specification of a media type and a subtype, separated by a slash. E.g. text/html or image/jpeg. Entire media types or individual subtypes can be selected.
| Media type | Description |
|---|---|
| application | Files that are linked to a specific application programme |
| audio | Audio files |
| image | Images, graphics, photos |
| message | Messages |
| text | Files with ASCII text |
| video | Video 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 the file formats that are linked to a specific programme or must be executed with special programmes or plug-ins. Subtypes that begin with an "x-" are files that are executed on a server.
