Re: Deny access to copy files

It looks very difficult situation. If programmers can *read* a file,
then can copy it no matter what file permissions you put. They can
just copy the code from the IDE and paste into a text file on USB
drive (its so non-technical). There can be many ways to hide data into
image files (or other file format) and email it or copy it. If its
very important then you may have to ban USB devices and disallow
internet access all together. Even a small access to outside world can
be exploited considering the people are programmers.

I am working for a software house, they are developing a software product
and their requirement is to restrict programmers to take the code out of
office premises due to company policy. I am trying to configure a windows
based machine which denies access to copy files to external storage devices
connected to USB. There is an NTFS permission "Read + Execute" I guess this
could do the work but is there any other way to do it?
They also don't need programmers to take the code with them in their email.
I can restrict SMTP and POP ports but when it comes to web based emails I am
clueless, How can I restrict web based emails like hotmail, gmail, yahoo
there are so many of these and if I somehow manage to block all web based
email sites someone can write a script to send emails, if not a script HTTP
tunneling would bypass any checks and bounds defined by my proxy/gateway
machine. How can I block such thing?
Any help would be highly appreciated.
