Cyber Threat Intelligence refers to the knowledge and insights gathered, analysed, and used to understand and predict cyber threats and attacks. This intelligence is crucial for organizations to proactively defend against potential cybersecurity threats and to respond effectively when attacks occur. This workshop focuses on the efforts of multiple EU-funded projects that have developed a Cyber Threat Intelligence (CTI) component, with a specific emphasis on IoT systems. The goal of this workshop is to equip participants with the skills and knowledge to gather, produce, elaborate, and share critical information about cyber threats and attacks, especially in IoT environments. The workshop also uniquely focuses on how CTI can be seamlessly incorporated into several vertical industries, addressing industry-specific challenges and needs.
