security analysis using Fault Trees (FT)

There are many previous work on using fault trees in reliability and availability modeling. Very few is on safety modeling and security modeling of cyber physical system. Fault trees are more powerful than reliability block diagrams (RBD) with shared nodes.

One potential idea is that I could transform the system model into fault trees and then compared them. Fault trees could be used to validate the system model. Fault trees are well suited for this purpose because they are specifically intended to capture the relationship between component failure and system faults, with an assumption that all basic events be statistically independent.

But there is a key problem here: What's your research object? At least there should be a real system or existing model you can investigate into, some people have there physical system like UAV, while some other people may have their SCADA simulation system. What do you have? Simulation model of NCS? Maybe.
