I meant the difference between safety-critical and security-critical systems, safety goals and security goals etc. It's all Sicherheit in German.
Schutz is protection. Can refer to both I guess. E.g. Datenschutz would be about security, while Arbeitsschutz is about safety.
Datenschutz is about legal protections for personal information (protection of the rights of the individual). Datensicherheit is about technical measures to ensure security of information (security).
