    Re: Restrict filetypes

    What we need is some kind of filter with the same technology as webfiltering like dansguardian that can scan mime type etc? Anyone any ideas on this?

    @face-man
    LOL Don't you just love script kiddies. They have the brains to embed the SWF but not the nouce to use a less obvious file name

    Linux has the 'file' command which can do this. For example:

    Code:
    root@anubis:/var/www/vle.carrhill.lancs.sch.uk/htdocs/moodledata/1# ls -l
    total 224
    -rwxrwxrwx 1 www-data www-data  5156 2006-09-06 07:04 800px-Canon_Digital_Ixus_40.jpg
    drwxr-xr-x 2 www-data root      4096 2006-09-12 19:23 backupdata
    -rwxr-xr-x 1 www-data root      7080 2006-05-19 16:10 cpt3.JPG

    -rwxr-xr-x 1 www-data root      5697 2006-05-19 16:10 diodes3.JPG
    -rwxr-xr-x 1 www-data root     20308 2006-05-19 16:10 diodes.JPG
    drwxr-xr-x 2 www-data root      4096 2006-05-16 12:50 flash
    -rwxr-xr-x 1 www-data root      4375 2006-05-19 16:10 game.JPG

    -rw-r--r-- 1 root     root      6624 2006-06-27 14:26 ipod2.JPG
    drwxr-xr-x 4 www-data root      4096 2006-05-16 12:50 moddata

    -rw-r--r-- 1 www-data root      6057 2006-05-19 16:10 rev2.jpg
    -rw-r--r-- 1 www-data root      8636 2006-05-19 16:10 rightlogo1.jpg
    -rw-r--r-- 1 www-data root      6625 2006-05-19 16:10 rightlogo1.OLD
    Scanned with 'file' gives:

    Code:
    root@anubis:/var/www/vle.carrhill.lancs.sch.uk/htdocs/moodledata/1# file *

    I believe 'file' is part of cygwin too, so it should be usable on windows.

    If you use software restriction policies in GPOs you can decide what counts as an executable.
    hmm - not working

    [set in user config > windows settings > security settings > software restrictions > enforcement]
