摘要: Several standards exist that target security assessment and certification. However, these support qualitative evaluation according to predefined levels. To trade-off between treatment strategies, we also need quantitative estimates of operational security. Quantitative evaluation, such as probabilistic analysis, is frequently used within the dependability domain. The quantify attributes has recently been raised. This relates both requirements in Quality Service (QoS) architectures, input decisions regarding design choice mechanisms. measure make mechanisms, separate treatments from primary functionality model, model strategies aspects using Aspect-Oriented Modeling (AOM). In this paper, develop a Bayesian Belief Network (BBN) based prediction system for estimating availability. Availability estimated variables mean time mis-use (MTTM), effort (METM), impact misuse (MI), frequency (MF). Misuses are addressed strategies. quality cost (TC) effect (TE).
