Secure design of Next Generation Infrastructures
Critical infrastructures are developing further into Next Generation Infrastructures (NGI). Today, we still have the chance to design NGI in a secure and safe way. Modelling denotes the action of designing and creating a conceptual model or a computational model or a CI model or a computer simulation. Other synonyms may apply as well.

[Click for more information]Simulation and Analysis (MS&A) may support the developers of NGI in:
- validating the robustness of their architecture and resilience of the design,
- verifying the robustness and resilience of the NGI with respect to its critical dependencies with other Critical Infrastructures (CI),
- validating the effectiveness of NGI emergency management processes in relation to new emergency challenges related to the NGI structure and See critical infrastructure

MS&A allows designers of NGI to experiment with different architectures and to explore the effect of various design choices including the security architecture. MS&A makes it possible to assess various options amongst different conditions, for instance varying in cyber threats, climate change effects, and other challenges.

Therefore, CIPRNet started with the idea that the secure design of NGI requires new infrastructure models and efforts to a) A single simulation model that interoperates with other simulations in a federation.

Discussions with both the NGI research communities and (critical) infrastructure operators made clear that the design of NGI mostly uses single fine-grained technical models at the one end of the spectrum, or coarse grain (EU-wide) grid assessment models with a nation being a grid node.
When looking at the life-cycle of infrastructures on the one hand, NGI stakeholders either look at the design and planning phase of infrastructures, and at the Modelling denotes the action of designing and creating a conceptual model or a computational model or a CI model or a computer simulation.

On the other hand, the federated models that are used by, for instance, the CIPRNet community, mostly address the prevention, preparation, response and recovery phases of crisis management. Some models bridge both worlds, e.g. analysis which aim to reduce infrastructure failure effect of uncertainty on objectives

Both communities face a set of similar challenges:

- The cyber A (network) component is an object in a CI model e.g. a generator, a pump, a transmission line, a physical transport, a node, a substation. Components have attributes and user-specified behaviour.

- NGI often looks at the economic impact of infrastructure design and infrastructure use and maintenance redesign. The interaction of these economic models less often takes place in the realm of crisis management support, but could help in what-if analysis during the preparation and recovery phases.
- Validation of models is not easy as there is a lack of proper reference data sets and studied outcomes.
