September 2018 | Ricarda Weber, Martin Wimmer

Thanks to modern digitisation and connectivity, it has never been easier to collect and analyse data relating to the state of production or automation equipment, for example in order to reduce the downtime of critical infrastructure. Digitisation and connectivity mean that infrastructures are connected to the internet and/or cloud computing platforms. However, opening up and interlinking networks comes with a dramatic increase in the risk of attacks on infrastructure systems.
