A power supply fails and takes a database offline. Under the standard definition, how should this be classified?

  1. A threat source, because a situation can exploit a weakness accidentally
  2. A vulnerability, because the hardware was old
  3. A residual risk, because the outage already happened
  4. It is not a threat, because no adversary was involved
Show the answer

Answer: A. A threat source, because a situation can exploit a weakness accidentally

A threat source can be intentional or accidental; a situation that exploits a weakness by chance still counts.
