A set of discrete threat events, associated with a specific threat source or multiple threat sources, partially ordered in time. Response:

A "Threat Scenario" precisely describes a sequence or set of discrete threat events, linked to one or more threat sources, occurring over time. It's a structured narrative or model used to understand how a threat might materialize and impact an organization, often used in risk assessment.

A "Threat Event" is a single adverse event, not a set or sequence of events.

A "Threat Source" is the actor or entity causing a threat (e.g., hacker, natural disaster), not the sequence of events itself.

A "Threat Assessment" is the broader process of identifying and evaluating potential threats, not the specific definition of a timed sequence of threat events.
