I'm studying for the CCSP exam and I came across this description:
An event is any unscheduled adverse impact to the operating environment. An event is distinguished from a disaster by the duration of the impact. We consider an event's impact to last three days or less; a disaster's impact lasts longer. An event can become a disaster. Causes of either/both can be anthropogenic, natural forces, internal or external, malicious or accidental.
This doesn't sound right to me. I thought that an "event", in and of itself, was neither good nor bad... it is an unplanned change of state in the environment. An "incident" seems to better align with description above which the purpose/affect is negative in nature.
I tried searching through other material and couldn't find clarification. Perhaps I'm remembering it incorrectly?
