In the domain of Cyber-Physical Systems (CPS), there is a significant concern regarding cybersecurity, especially for smart manufacturing systems, allegedly a target of numerous recent cyber attacks. Given this situation, this paper introduces a simulation-based model to assess the repercussions on manufacturing systems’ performance under the presence of cybersecurity issues. The objective is to validate countermeasures regarded as a Dynamic Intrusion Response, which could potentially reduce the adverse impact of specific malicious cyber attacks. The effectiveness of adjusting dynamic scheduling policies in response to cyber-attacks has been evaluated through a simulation study based on a manufacturing system. The results reveal that adaptive real-time scheduling policies such as dynamic resource allocation and rerouting of jobs will efficiently reduce the adverse impact of cyber attacks on an open-shop manufacturing environment.
