Re: Deny access to copy files

Hello Ahmed,

Sounds more like you try washing your hands without getting wet :)
I can hardly imagine, that the programmers should be able to read but
not to copy, so if they need to programm they need access to the code.
I think its more frustrating for programmers to know that they have to
work with "handcuffs".
I think the problem lies much deeper :
do you trust your programmers?
If not, hire another, if yes, no such measurements needed, or better
say not more than written agreements about security policy.
About blocking web access:
As i can remember that one of the core problems of security is that
you cannot protect your data efficiently from attackers within the
company.
I can remember about agreements which contain things like:
-not connecting mobile storage devices to the workstation (this can be
monitored)
-not connecting mobile devices to the internal network (this can also
be monitored)
-not taking parts of code out of the company (which can also be
monitored)

Of course, bad-intentioned people will be able to bypass such
agreements but i preffer to assume that in your staff are good people
only.
One more - what about using interfaces for programming? Doing so,
every one holds only a small, unusable piece of the "puzzle".
