Fig. 4From: Bayesian network model to distinguish between intentional attacks and accidental technical failures: a case study of floodgatesConstructed Qualitative BN Model. (In this Figure, the presence of contributory factors and observations (or test results) colored in dark red would increase the likelihood of the problem (colored in red) due to an attack on the sensor. Furthermore, the presence of contributory factors and observations (or test results) colored in orange would increase the likelihood of the problem due to sensor failure)Back to article page
