  2. Risk matrix - Wikipedia

    en.wikipedia.org/wiki/Risk_matrix

    A risk matrix is a matrix that is used during risk assessment to define the level of risk by considering the category of likelihood (often confused with one of its possible quantitative metrics, i.e. the probability) against the category of consequence severity. This is a simple mechanism to increase visibility of risks and assist management ...

  3. IT risk management - Wikipedia

    en.wikipedia.org/wiki/IT_risk_management

    Risk management as a methodology has been criticized for its subjectivity, particularly in assessing the value of assets and the likelihood and impact of threats. The probabilistic models often used may oversimplify complex risks. Despite these criticisms, risk management remains an essential tool for managing IT risks. [1]

  4. IT risk - Wikipedia

    en.wikipedia.org/wiki/IT_risk

    Many NIST publications define risk in IT context in different publications: FISMApedia [9] term [10] provide a list. Between them: According to NIST SP 800-30: [11] Risk is a function of the likelihood of a given threat-source’s exercising a particular potential vulnerability, and the resulting impact of that adverse event on the organization.

  5. Risk assessment - Wikipedia

    en.wikipedia.org/wiki/Risk_assessment

    Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [2]

  6. Common Vulnerability Scoring System - Wikipedia

    Subsequent System Integrity Impact (SI): [N] none, [L] low, or [H] high. Subsequent System Availability Impact (SA): [N] none , [L] low , or [H] high . Additionally to these base metrics, there are optional metrics regarding public availability of an exploit, environment specific thread modelling, system recovery, and others.

  7. Probabilistic risk assessment - Wikipedia

    en.wikipedia.org/wiki/Probabilistic_risk_assessment

    Probabilistic risk assessment (PRA) is a systematic and comprehensive methodology to evaluate risks associated with a complex engineered technological entity (such as an airliner or a nuclear power plant) or the effects of stressors on the environment (probabilistic environmental risk assessment, or PERA).

  8. DREAD (risk assessment model) - Wikipedia

    en.wikipedia.org/wiki/DREAD_(risk_assessment_model)

    It was initially proposed for threat modeling but was abandoned when it was discovered that the ratings are not very consistent and are subject to debate. It was discontinued at Microsoft by 2008. [2] When a given threat is assessed using DREAD, each category is given a rating from 1 to 10. [3]

  9. Risk breakdown structure - Wikipedia

    en.wikipedia.org/wiki/Risk_breakdown_structure

    Risk analysis is more easily achieved if, after identification, the risks are placed in proper perspective within the RBS by categorizing the risks in the various levels. Risk analysis involves the use of techniques for prioritizing the risk, determining the probability of the risk, and calculating the impact of the risk.
