Abstract
On top of information technology (IT) security risks faced by almost all companies, manufacturers need to deal with additional challenges from operating their own factories. For example, typical difficulties arise from legacy systems, proprietary communication protocols and real-time requirements in highly automated production environments. At the same time, budget constraints need to be considered, as manufacturers often face strong competition (plants are usually unprofitable at low utilisation, and therefore each competitor has a strong incentive to lower prices down to the marginal cost of production). This paper explains the combined IT and operational technology (OT) security concept used by a corporation with a global manufacturing footprint operating in various industry sectors. Lessons learned from testing some security tools are included. In order to scale know-how and make security more affordable for companies in similar situations, the concept of a curated marketplace is introduced, and its implementation described.
