Short answer While ZF takes and provides some measures to secure your app, you should still apply the same precautions that you'd use without Zend Framework.
The same concept is valid for the Zend Framework and for every other web application/library/whatever that manipulate user data.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
