How do you identify the weakest links in your IoT network? How do we justify cost and benefits of security mitigation measures in a digital manufacturing plant?
In this talk, we will share about our innovative approach to quantitatively measure the vulnerability and damage of the Confidentiality, Integrity and Availability (CIA) of data.
Our work based on critical infrastructures is applicable to IoT and SCADA networks. Manufacturing enterprises will be able to fine tune their cyber security implementations and spending, and reduce under or over protection. Our data-driven approach to conceptualise and develop the essential metrics, namely, Damage Index (DI) and Vulnerability Index (VI) that quantify the extent of damage an IoT or Manufacturing networks due to a cyber attack. We will also share a use case of computing the metrics for an academic lab that undertakes commercial manufacturing projects in Singapore is demonstrated. This work builds a strong foundation for development of an adaptive cyber security architecture with optimal use of IT resources for manufacturing enterprises.
