Definition should include the distinctions between risk, vulnerability, and threat.

Definition should state that

risk is the likelihood that a vulnerability will occur and that a loss occurs if that vulnerability is exploited
vulnerability refers to a flaw in a system that can leave it open to attack; it may also refer to any type of weakness in a computer system, in a set of procedures, or in anything that leaves information security exposed to a threat.
threat refers to an action that might exploit a vulnerability and cause potential harm (e.g., cyber, terrorism, pandemics, extreme weather, accidents, technical failures).
