Abstract: In an example, a component analyzer can compute a respective part score for each part of the platform based on a part property table, and a respective connection score for each connection of the platform based on a connection property table. The component analyzer can provide the respective part and connection scores as score data to an architecture modeling engine to compute a probability model based on the score data and an architecture model. The probability model can include a part probability value and a connection probability value, and the architecture model can characterize a target architecture of the platform. A survivability analysis engine can evaluate the probability model and the architecture model to determine a likelihood that one or more potential cyber-attacks on the platform based on the target architecture are successful or unsuccessful in compromising at least one part of the platform.
