The aim is to outline the framework of a generic methodology for speci
fying countermeasures in health care environments. The method is speci
fically aimed at the enhancement of security in existing health care s
ystems, and a key element is the use of predetermined 'profiles' by wh
ich these may be classified. Example scenarios are presented to illust
rate how the concept could be applied in practice. The paper is based
upon work that was initially carried out as part of the Commission of
European Communities SEISMED (Secure Environment for Information Syste
ms in MEDicine) project, the aim of which is to provide security recom
mendations for European health care establishments (HCEs).
