Seeking the Relation Between Performance and Security in Modern Systems: Metrics and Measures

Abstract

Nowadays, the security, safety and performance became a crucial part of the product life cycle (PLC) in which the requirements for these parameters are continuously growing. Therefore, it is a very challenging task to provide an efficient, well-balanced solution with fulfilling all these requirements. We are focused on the relations between security, safety and performance. This paper contains early-stage results and provides a summary of security requirements based on the selected current standards and recommendations such as IEC 62443 or NIST 800–57, and our best practices. Moreover, we introduce the relations between security and performance based on established requirements. We also provide examples of security impact on performance with using open data measurements. Last but not least, the results of this article might be used in the PLC, i.e., co-engineering, future system development or research on multiparametric methods.
