In an age of digital information and communication, cybersecurity threats cannot be avoided even in the healthcare industry. In fact, healthcare information infrastructures (HCIIs) are targets due to their increasing digital interconnectivity. As such, there is an urgent need for health service operators to protect HCIIs. The EU-funded AI4HEALTHSEC project will develop a solution that improves the detection and analysis of cyberattacks and threats on HCIIs. The aim is to build situational awareness and incident handling and risk assessment among HCIIs.
