Assignments of EAI on IT architecture within enterprises

Abstract
This paper discusses the impact of IT security in our information society. It also demonstrates that IT security has become a very import economic factor for enterprises. As IT security should be seen as an enabling technology for new application areas like e-business, the paper presents the main problems that must be solved in the near future in order to overcome existing deficiencies. To this end, a tight cooperation between research groups and industrial partners is required to produce EAI (enterprise application integration) solutions that are pragmatic but also strong enough to fulfil security requirements.
