Trick to keep in mind+3 XP
Read, write, run: C is who may read it, I is who may change it, A is whether it runs when needed.
Each letter names a different kind of damage. A leak breaks who can read the data, a silent edit breaks whether you can trust what is stored, and an outage breaks whether people can use the service at all. When a scenario describes an incident, ask which of those three things actually went wrong. Other properties can be missing without the others being touched.
Read it once, then a question tests whether the trick stuck.
