MIME Header wild card

AhmedMaher

In Sophos UTM I used to put video/* in the blocked MIME type list and it would block all videos

I tried doing the same in Sophos XG by creating a new file type and add video/* in the MIME header field and a use it in a web policy to block video files but it does not work

Are wild cards supported in MIME headers like Sophos UTM?

    In 16.01 and 16.05.
    Left menu, web.
    Tab "Protection"
    The first grouping of settings is "Malware Scanning" where you can select the Scan Engine Selection, etc.
    Below the Scan Engine Selection there is "Advanced Settings" with a little triangle.  Click on it to expand.
    You should now see additional options including a "Scan audio and video files".

     

    When this is unchecked, if the web server has in the header that the file is a video/mpeg (for example), then the proxy will not virus scan the file and it will tunnel the content directly to the client.

    When this is checked, if the web server has in the header that the file is a video/mpeg (for example), then the proxy will treat it as a normal file download and will do either batch or real time scanning etc like any other file.

     

    I think what you were talking about is the "File Types" tab, which is a file type definition that can then be used in policy.  The checkboxes are just for multi-select deletion.

    Thank you, found it, bit obscure, but never mind, now wiser.
