This course focuses on using real-world data for protecting data and systems from cyberattacks. The course will be divided into two main thematic parts: cyber threat intelligence, which focuses on methods on using information about past cyberattacks and known attacker groups, and empirical research in human factors in security, focusing on studying human behavior in security-critical systems. The course is aimed at students with a background in computer science/data science with basic knowledge of cybersecurity.
