What is the definition of a threat in a security context?

In a security context, the definition of a threat is best characterized as the potential to do harm to a system. This understanding acknowledges that a threat represents any circumstance or event that could exploit vulnerabilities and cause damage to the integrity, confidentiality, or availability of a system or its data.

This potential is not conditional on the ability to carry out an attack, rather it is simply the existence of a danger that could manifest negatively. An example would be a natural disaster, such as a flood or earthquake, or malicious actions, such as hacking or malware. Recognizing a threat as merely a potential allows organizations to assess risks and implement appropriate measures to mitigate possible impacts before they occur.

The other options delve into aspects related to threats but do not align with the fundamental definition. They address aspects like existing capabilities or results of threats, but they do not capture the essence of a threat itself, which is fundamentally about the possibility of harm.
