A Security Architecture is a conceptual design that addresses various aspects of security in a system and resulting application, set of applications and components that make up the system. It is being used to support the design, development, implementation and operation of these systems, which can include Manufacturing Platforms. For Digital Manufacturing Platforms it addresses necessities and potential risks identified following potential scenario's or within a specific environment. It tries to present a comprehensive perspective of various security concepts on the conceived OT and IT architecture which includes networks, systems and equipment connected to these networks, the communication protocols and operating systems being used, the application development and operational process and recommends the use of security measures using security controls. Having a Security Architecture also helps both the design and integration process, supports identification of incidents and the security monitoring, speeds up discussions with partners for a level play field and best practices and is generally reproducible. Digital Manufacturing Platforms tend to try to bridge operational systems with information technology, such as the use of analytics, data collection and distribution and visualization that can lead to automated actions by these systems on the basis of unattended and unsupervised decisions and control implementations. To avoid physical harm, collateral damage other safety or cybersecurity issues, having a Security Architecture supporting the Digital Manufacturing Platforms should allow developers and companies at least to consider the various aspects and challenges of security in an organized and comprehensible manner. Architectures can follow standards such as IEC62443, ISO27k or NIST800.16, or any alternative scheme, but that needs to complete towards the digital and operational platforms.
