Resum

Healthcare is undergoing a digital transformation at several levels, which is beneficial in many ways including efficient medical data exchange and better treatment of patients among others. However, this transformation comes with a cost as digitalization often entails increased number of threats and attacks. Therefore, it should not come as a surprise that the number of security breaches over the past years has increased in the healthcare domain. As a matter of fact, the healthcare sector has become the prime target of many adversaries and hackers. The outbreak of Covid-19 spiked malicious actions targeting healthcare organizations by launching a series of phishing campaigns and ransomware attacks. Attacking also medical devices and their functionality integrity poses a serious threat as it puts human lives at risk. These cybersecurity incidents are reminders to the healthcare industry to closely reevaluate their current security posture and put forward security controls to fortify their defense against malicious actions. This chapter presents the most significant assets and threats for the healthcare domain as well as real-word cybersecurity incidents and subsequently provides a set of critical technical measures and mechanisms of top-priority that should be implemented by healthcare organizations. Complementary to technical solutions, this chapter outlines legislations and directives that are relevant to the healthcare domain and should be considered. Finally, this chapter identifies the need of information sharing and its benefits for healthcare including the better treatment of rare diseases. To this end, the blockchain technology is evaluated as a solution for information sharing and medical data exchange in a trustworthy and secure manner.
