The prevalence of security risks and the subsequent attacks on Cyber-Physical Systems (CPSs) have reached unprecedented levels. Anomaly-based Intrusion Detection Systems (Ab-IDS) emerged in response to this phenomenon, with the purpose of alerting actors in the event of an attack. However, with the advent of Industry 4.0 and smart manufacturing, CPSs have evolved into progressively more complex systems, giving rise to the Cyber-Physical System of Systems (CPSoS) that imposes a wide range of requirements. In light of this problem, we first identify a set of requirements in this problem space and further derive a novel architecture design for that aims to incorporate Ab-IDS into complex CPSoS environments.
