Cyber risks are increasingly widespread as healthcare organizations play a defining role in society. Several studies have revealed an increase in cybersecurity threats in the industry, which should concern us all. When it comes to cybersecurity, the consequences can be felt throughout the organization, from the smallest processes to the overall ability of the organization to function. Typically, a cyberattack results in the disclosure of confidential information that undermines your competitive advantage and overall trust. Healthcare as a critical sector has, like many other sectors, a late bet on its transformation to cybersecurity across the board. This dissertation reinforces this need by presenting a value-added solution that helps strengthen the internal processes of healthcare units, enabling their primary mission of saving lives while ensuring the confidentiality and security of patient and institutional data. The solution is presented as a technological composite that translates into a methodology and innovative artifact for integration, monitoring, and security of critical medical infrastructures based on operational use cases. The approach that involves people, processes, and technology is based on a model that foresees the evaluation of potential assets for integration and monitoring, as well as leveraging the efficiency in responding to security incidents with the formal development of a process and mechanisms for alert and resolution of exposure and attack scenarios. On a technical level, the artifact relies on the integration of a medical image archiving system (PACS) into a SIEM to validate application logs that are linked to rules to map anomalous behaviors that trigger the incident management process on an IHS platform with custom-developed features. The choice for integration in the validation prototype of the PACS system is based not only on its importance in the orchestration of activities in the organization of a health institution, but also with the recent recommendations of various cybersecurity agencies and organizations for the importance of their protection in response to the latest trends in cyberattacks. In line with the results obtained, this approach will have full applicability in a real operational context, following the latest practices and technologies in the sector.
