Standard Definition
ISO/IEC 27000:2014
Effect of uncertainty on objectives [4](based on the ISO Guide 73:2009[5]).
- An effect is a deviation from the expected — positive or negative.
- Uncertainty is the state, even partial, of deficiency of information related to, understanding or * knowledge of, an event (2.25), its consequence, or likelihood.
- Risk is often characterized by reference to potential events and consequences, or a combination of these.
- Risk is often expressed in terms of a combination of the consequences of an event (including changes in circumstances) and the associated likelihood of occurrence.
- In the context of information security management systems, information security risks can be expressed as effect of uncertainty on information security objectives.
- Information security risk is associated with the potential that threats will exploit vulnerabilities of an information asset or group of information assets and thereby cause harm to an organization.
