Part 3 (Applying Ethics to Cybersecurity) contains three introductory lectures. The first lecture demonstrates the challenges of applying frequently used frameworks to problems in cybersecurity. The insights gained in this lecture can be immediately applied on a contemporary dilemma (autonomous cars), which is presented afterwards. The second lecture introduces the cybersecurity objectives within the European Union and how they relate to commonly shared values. The third and final lecture of this part focuses on the handling of value conflicts. This lecture is followed up by a short video in which a security researcher describes a particular value conflict.
