Trust but verify. Good employment contracts, monitor use and access. Log and validate email. Us an IDS with code functions as search matches... A good contract will let you stop most code that leaks as the company it goes to can be estopped from making use of it. Make receipt of the code a big enough risk on its own.

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.
If you can't trust your developers: fire them. Trying to restrict them by enforcing policies is pointless. If they're unable to thwart whatever measure you throw at them either their environment is too ristrictive for them to be able to work efficiently (which is counter-productive for the company), or they're incompetent (in which case you may want to find someone better).
