Security And Privacy Assurance Suite
In the realm of organizational security, several crucial endeavours emerge. The first involves certifying the security attributes of services, ensuring they adhere to established standards for safeguarding user data and interactions. Simultaneously, security assessments and certifications for industrial sites are imperative, scrutinizing physical and digital safeguards to fortify critical infrastructure. Evaluating and certifying processes constitute another facet, embedding security measures into operational workflows to mitigate vulnerabilities. Additionally, the pursuit of economical solutions for security audits remains vital, allowing comprehensive evaluations of security systems, policies, and practices without excessive financial burdens.

Shared situational awareness, preparedness and coordinated incident response in alignment with the NIS Directive-established EU cybersecurity structures and mechanisms.
Cybersecurity incidents have shown that the healthcare sector is one of the most vulnerable to cyberattacks. National Cyber Security Authorities, regulators, policymakers and insurance companies lack a benchmarking methodology and relevant KPIs for assessing the cyber-security status of organisations belonging to a particular domain, especially health. At the same time, there is no unified platform to observe the security status of electronic devices and provide real-time forensics in healthcare environments, such as a group of hospitals and medical centres.
A cybersecurity solution that offers automated and up-to-date information on how a particular organisation stacks up against other entities belonging to the same domain along with tools for effectively monitoring and understanding a hospital’s cybersecurity status in real-time.
The Observatory, in a large scale of connected hospitals, serves as a key means of measurement of cybersecurity status among healthcare organizations. The Risk Assessment for Medical Applications (RAMA) provides a score and metadata that could help the assessed healthcare organization realize its security posture. The Global RAMA Score is a weighted sum of the Local RAMA aggregated scores of the HEIR-connected hospitals. As a result, the Global RAMA Score may be compared to the Local Rama Score of the connected hospitals, thus understanding the hospital’s cybersecurity status in real-time. Furthermore, the Active Policies of the Observatory can be used as a knowledge base for policy makers. There is no alternative solution to this issue, thus Observatory as a service is innovative. Finally, the cybersecurity status of hospitals may be used by insurance companies to offer more attractive contracts and handle cybersecurity claims.
As technology advances, there is a growing need for effective and efficient tools to deal with the increasing number and frequency of cyber-attacks. Specifically, the increasing sophistication of cyber-attacks led organizations to increasingly seek comprehensive threat detection and response capabilities to counter these sophisticated attacks effectively. Organizations across various sectors, including finance, healthcare, and e-commerce, recognize the importance of proactive threat detection and prevention. The market is highly competitive, with several established players and emerging startups offering real-time threat-monitoring solutions.

Forensics Visualisation Toolkit (FVT)
Difficult exploration from big volumes of multidimensional data could lead to slow reactions in cases of security breaches as well as not discovering potential threats.
Digital forensics analysis, also known as computer forensics or cyber forensics, focuses on investigating and analyzing digital devices and electronic evidence to uncover information related to cybercrimes, data breaches, and other digital incidents. It involves the identification, preservation, extraction, and interpretation of data from various digital sources. Digital forensics analysts utilize specialized tools, such as the Forensics Visualization Toolkit (FVT), and techniques to examine digital devices such as computers and network systems.
FVT offers a solution that can handle large number of heterogeneous events and provide intuitive visualisations for IT and non-IT experts that reveal hidden relationships and insights.
Local and Global RAMA
Although the healthcare sector has been capitalizing on digital advancements to improve patient outcomes and experiences substantially, poor security practices are still heavily used. Poor computer and user account security, remote access and home working, and lack of encryption are critical issues in the healthcare sector. These, in combination with the lack of up-to-date risk assessment techniques and security awareness, have led the healthcare sector to be one of the most impacted in terms of average data breach cost, as well as be the sector that faces the most significant influx of cyber-attacks, regarding both volume (69%) and complexity (67%).
HEIR advances the state-of-the-art by proposing a novel Risk Assessment for Medical Applications (RAMA) score, which acts as a benchmark and estimates medical devices' attack surface and resilience by incorporating several critical issues. The Local and Global RAMA Score incorporates several critical issues reported by a centralized client and estimates the attack surface and the resilience of the underlying medical devices per healthcare organization.
The Local and Global RAMA score are innovative risk assessment metrics that were defined and developed within HEIR. The proposed solutions were based on existing state-of-the-art solutions, such as the CVSS, and are tailored -but not explicit- for the healthcare sector.
Access to sensitive medical data needs to be strictly controlled in order to be compliant with regulatory laws. Data access policies may change over time, and therefore should not be hardcoded into application logic. Additionally, traditional role-based access control (RBAC) systems do not give fine-grained access to such attributes within healthcare models.
