Variable to which a value is assigned as the result of measurement [1]. The term “measures” is used to refer collectively to base measures, derived measures, and indicators. [2]
Measurement refers to a process to determine a value. [2]
In the context of Information Security the process of determining a value requires information about the effectiveness of an information security management system and its associated controls using a measurement method, a measurement function, an analytical model, and decision criteria.
- Measurement function is algorithm or calculation performed to combine two or more base measures. [3]
- Measurement method is logical sequence of operations, described generically, used in quantifying an attribute with respect to a specified scale [4]. The type of measurement method depends on the nature of the operations used to quantify an attribute. Two types can be distinguished:
- subjective: quantification involving human judgment;
- objective: quantification based on numerical rules.
- Measurement results are one or more indicators and their associated interpretations that address an information need.
- Decision criteria refer to thresholds, targets, or patterns used to determine the need for action or further investigation, or to describe the level of confidence in a given result [5].
- Analytical model is algorithm or calculation combining one or more base measures and/or derived measures with associated decision criteria.
