An information security incident can impact more than one asset or only a part of an asset. There has been quite a bit written about information security risk assessments. A threat refers to a new or newly discovered incident that has the potential to harm a system or your company overall.

Thus, impact valuation is not performed separately, but is embedded within the asset valuation process. If the impact is expressed in monetary terms, the likelihood being dimensionless, then risk can be also expressed in monetary terms. What follows is a brief description of the major types of security assessment, along with what differentiates them from commonly confused cousins. Vulnerability is “a weakness of an asset or group of assets that can be exploited by one or more threats. Organizations express risk in different ways and with different scope depending on which level of the organization is involved—information system owners typically identify and rate risk from multiple threat sources applicable to their systems, while mission and business and organizational characterizations of risk may seek to rank or prioritize different risk ratings across the organization or aggregate multiple risk ratings to provide an enterprise risk perspective. Thus, risk R is a function of four elements: (1) V, the value of the assets; (2) T, the severity and likelihood of appearance of the threats; (3) V, the nature and extent of the vulnerabilities and the likelihood that a threat can successfully exploit them; and (4) I, the likely impact of the harm should the threat succeed: that is, R = f(A, T, V, I). A direct impact may result because of the financial replacement value of a lost (part of) asset or the cost of acquisition, configuration, and installation of the new asset or backup, or the cost of suspended operations resulting from the incident until the service provided by the asset(s) is restored. Harm, in turn, is a function of the value of the assets to the organization. Risk response is a planning and decision making process whereby stakeholders decide how to deal with each risk. Finally, it also describes risk handling and countermeasures. Wikipedia: > "Security risk management involves protection of assets from harm caused by deliberate acts. Threat is an event, either an action or an inaction that leads to a negative or unwanted situation. Impact is related to the degree of success of the incident. Also the organization’s geographical location will affect the possibility of extreme weather conditions. In practice, qualitative analysis is often used first to obtain a general indication of the level of risk and to reveal the major risks.
