- The present study originated from a realisation about the unique nature of the medical domain and about the limitations of existing risk-management methodologies with respect to incorporating the special demands and salient features of the said domain. A further incentive for the study was the long-felt need for proper Information Technology (IT) risk management for medical domains, especially in the light of the fact that IT is playing an ever-greater part in the rendering of health-care services. This part, however, introduces new information-security challenges every day, especially as far as securing sensitive medical information and ensuring patients' privacy are concerned. The study is, therefore, principally aimed at making a contribution to improving IT risk management in the medical domain and, for this reason, culminates in an IT risk-management model specifically developed for and propounded in the medical domain. While developing this model, special care was taken not only to take into consideration the special demands of the said domain when assessing IT risks but also that it would be suited to the concepts, terminology and standards used in and applied to this domain every day. The most important objectives of the study can be summarised as follows: A thorough investigation into modern trends in information security in the medical domain will soon uncover the key role IT is playing in this domain. Regrettably, however, this very trend also triggers a steep increase in IT riskincidence figures, which, in this domain, could often constitute the difference between life and death. The clamant need for effective risk-management methods to enhance the information security of medical institutions is, therefore, self-evident. After having explored the dynamic nature of the medical domain, the requirements were identified for a risk-management model aimed at effectively vi managing the IT risks to be incurred in a typical medical institution. Next, a critical evaluation of current risk-assessment techniques revealed that a fresh approach to IT risk management in medical domains is urgently necessary. An IT risk-management model, entitled "RiMaHCoF" (that is, "Risk Management in Health Care — using Cognitive Fuzzy techniques"), was developed and propounded specifically for the medical domain hereafter. The proposed model enhances IT risk management in the said domain in the sense that it proceeds on the assumption that the patient and his/her medical information constitute the primary assets of the medical institution.
