This is our project report on the subject of hardening project systems on a Linux basis and with the Oracle database on top. Since it has come to us completely out of the blue, even as "Oracle users" and "Linux users" with many years of experience, we first looked around and wondered what is to be learned in the security environment! It is the story of criminal energies, self-restrictions, risks to be taken, unknown threats, dear habits, external determination, reality, practice, performance, overhead, overview, tools and the question of who is supposed to maintain all this?

Join us on the road which should lead to greater security - but at what cost?
