Digital ethics is about thinking beyond what technology allows you to do and considering what you should do.
A technical opportunity does not automatically give you permission. Finding an exposed account, accessing an unlocked device or discovering information that is not meant for you does not make it appropriate to explore, copy or share.
Digital ethics includes honesty, privacy, consent, respect and fairness. It also means considering the effect your actions may have on people who may never know what happened.
When you are unsure, pause before acting. Ask whether you have permission, whether the information belongs to you, whether someone could reasonably be harmed, and whether there is a safer way to achieve what you need.
