Cyber attacks and IT security management in 2025Radar Cyber Security

The document discusses the results of an expert survey about future cyber attacks and IT security challenges in 2025. Experts predict that (1) attacks on the Internet of Things will increase, (2) next generation malware will be more sophisticated and precise, and (3) social engineering attacks targeting users will rise. To combat these threats, IT security needs to offer advanced artificial intelligence for quick response and automated detection of targeted attacks, as well as new authentication methods. Experts say the biggest challenges are users' lack of security awareness, exploding data volumes, lack of coordination against cybercrime, and fast technological changes like the IoT. Companies must increase security training and continuously improve automated data analysis and secure cloud solutions to ensure IT security
