Risk

Computer security

 * 1) In the field of computer security, the term risk is “the expectation of loss expressed as the probability that a particular threat will exploit a particular vulnerability with a particular harmful result.”
 * 2) Risk is a combination of the likelihood that a particular vulnerability in an organization’s systems will be either intentionally or unintentionally exploited by a particular threat agent and the magnitude of the potential harm to the organization’s operations, assets, or personnel that could result from the loss of confidentiality, integrity, or availability.
 * 3) Risk is "a measure of the extent to which an entity is threatened by a potential circumstance or event, and typically a function of: (i) the adverse impacts that would arise if the circumstance or event occurs; and (ii) the likelihood of occurrence." Risk in the 21st century results from a complex mix of man-made and naturally occurring threats and hazards, including terrorist attacks, accidents, natural disasters, and other emergencies. Within this context, critical infrastructure and key resources (CIKR) may be directly exposed to the event themselves or indirectly exposed as a result of the dependencies and interdependencies among CIKR.
