> First of all, that's security, not safety. Lots of software exists in an environment where it isn't going to be attacked. I use the terms interchangeably on purpose, because safety and security are really two sides of the same coin. In the past, I've worked in security and I now work in a domain where safety is critical. It's my experience that the two fields have considerable overlap. We can always get better at interdisciplinary sharing of knowledge.
