I doubt it's possible. To keep them from physically bringing the code
with them, you'd have to disallow the use of any external storage
devices (this can probably be done with group policies), since they
could otherwise just copy the source to a text file saved on a USB
stick. Preventing them from digitally sending the source code over the
internet would be near-impossible (if not impossible). There are
simply too many different ways to do it (use webmail services, use
anonymous mail services, upload the plain text to a website, etc...).
The only way to prevent that is to scan every packet for the source
code contents, and that's just not practically feasible. Not to
meantion encrypted VPN, which would also have to be blocked somehow.
I'd say your best bet is to tell the programmers that bringing the
source code home is not acceptable, and make sure there are

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.
