In the FCM (Factor-Criteria-Metrics) model the quality of software is decided by some Factors, each Factor is decided by some Criteria, each Criteria is decided by some Metrics. The measure method based on Multi-data and Layer has certain likeness with network safety valuation, because the core task of network safety valuation is to measure the target network on the aspects of managing strategy and technique , the two safety valuation factors, whether it matches the request of appointed safety protection grade. In this paper, we proposed a network security evaluation based on Factor-Criteria-Metrics.[1]


FCM (Factor-Criteria-Metrics) Model
source: Queen Mary University of London


The model is usually constructed in a tree-like fashion. The upper branches hold important high-level quality factors of software products, such as reliability and usability, that we would like to quantify. Each quality factor is composed of lower-level criteria, such as modularity and data commonality. The criteria are easier to understand and measure than the factors; thus, actual measures (metrics) are proposed for the criteria. The tree describes the pertinent relationships between factors and their dependent criteria, so we can measure the factors in terms of the dependent criteria measures. This notion of divide-and-conquer has been implemented as a standard approach to measuring software quality [ISO 9126].
