In the context of cyber-physical systems, safety and security have been discussed and dealt with separately in the past, since security was not a critical issue of safety and vice versa. They are similar in some points, and it is natural to try dealing with them in parallel or in a unified manner. This paper considers symmetrical treatment of safety and security, especially in identifying possible harms. We compare the result of hazard analysis and threat analysis for a single model of a small IoT system. It shows that identified harms have much overlaps, which indicates the two analyses can be unified.
