I. Anomaly Detectors
Cyber-physical infrastructures or Systems of Systems are composed of many different software layers and a multitude of services. Due to the complexity, dynamicity and governance of these systems, instrumenting each individual service for monitoring purposes and characterizing all the possible errors or attack that may manifest is often not feasible [23], despite being widely acknowledged as crucial. To such extent, anomaly detection [1] was proposed; it deals with the problem of finding patterns in data that do not conform to the expected behavior.
