This event, presented by DG HOME, aims to bring together practitioners, local authorities, policymakers, and researchers to discuss trends, risks, further research, and lessons learned from major public events in 2024. The focus will be on security research needs, new threats, advanced technologies, crisis preparedness, and ethical and legal considerations. Major public events, such as international sporting championships and large music events, pose significant security challenges due to their complexity and scale, attracting global attention and large crowds, making them potential targets for threats like terrorism and cyberattacks. The event highlights the critical need for cutting-edge security measures.
