The probability that a threat to an information system will materialize is called "Risk". Risk is the likelihood of a threat exploiting a vulnerability, resulting in damage or loss to an asset.
Threat refers to any potential danger or harm that could impact the confidentiality, integrity, or availability of an information system. A threat can be natural, accidental, or intentional, and can come from internal or external sources.
Vulnerability refers to weaknesses or flaws in a system's design, implementation, or operation that can be exploited by a threat to gain unauthorized access or cause damage.
A hole is a term sometimes used synonymously with vulnerability, but it is not a standard term in the field of information security.
In summary, risk is the probability that a threat will exploit a vulnerability, resulting in harm to an asset, and it is an essential concept in information security that helps security administrators assess and manage the security posture of an organization's information systems.
