Threat

A threat is an unwanted (deliberate or accidental) event that may result in harm to an asset. Often, a threat is exploiting one or more known vulnerabilities.

A threat can also be any perception of insecurity; such as a risk.

A threat is also an explicit or implicit message from a person to another that the first will cause something bad to happen to the other, often except when certain demands are met. Often a weapon is used. Examples are a robbery, kidnapping, hijacking, extortion, blackmail.

The message may be vague and implicit in an attempt to avoid blame, including legal consequences, while still clear enough to serve its purpose.
