Sicherheit, insbesondere mehrseitige IT-Sicherheit

Security, in respect of information technology (IT) systems, refers to the fact that protection goals are achieved in spite of intelligent attacks. This paper commences with a brief discussion of the term security in the context of IT systems. Of particular importance is the broadening of the term's meaning which has resulted from the development and more widespread deployment of IT, in particular IT supported communication systems. This is followed by a description of potential attackers and, subsequently, an explanation and example of security requirements arising from several perspectives (multilateral security). The paper concludes with a brief discussion of the opportunities for implementing multilateral security in distributed systems.
