Towards Automated Security Evaluation within the Industrial Reference Architecture

The current developments towards the visions of Industrie 4.0 will create open and dynamic architectures being supervised by Industrial Automation and Control Systems. Due to this new connectivity and flexibility, future industrial production systems need to be inspected during all phases of the whole lifecycle from a security point of view as well. Frequent reconfiguration and adaptation based on smart services impose advanced requirements on the audits and certification with regard to security. To facilitate that, this work presents an approach for the modeling of security requirements and capabilities within the Industrial Reference Architecture and evaluates it based on the concrete system architectures of a number of industrial use cases. The result is the Sec4ICS tooling-based concept for the automated assessment of security-related functionalities within industrial systems.
