The talk offers a clear and practical introduction to the field of cybersecurity; what it is, what it involves, and how it connects to everyday systems and research environments. We’ll explore how security teams operate (red, blue, and purple), how attacks are detected and countered, and how the global threat landscape looks in 2025 based on the latest ENISA findings. The goal is to make the subject approachable and relevant to researchers from any discipline, highlighting why cybersecurity matters to everyone working with data, networks, or connected systems.
