Common Criteria (CC) is the world-wide standard for IT security evaluations. It covers products ranging from firewalls to smartcards (credit and debit cards, Apple pay, ePassports etc), photocopiers to fighter jet parts, and software to hardware…
I’ve been in this world for 15+ years now, as consultant, evaluator, certifier, and trainer. It is pretty likely you are interacting with a device whose CC evaluation I’ve been involved in, on a daily, if not hourly, basis.
If you see a post about IT security, I was likely influenced by my experience in this domain.
