Abstract:

The evolution of the ongoing energy transition reveals some critical limitations regarding cybersecurity in the energy sector. This is associated with opening the control system to the internet and thus creating opportunities for adversarials to break into the critical infrastructures. Additionally, new and untested technology could harm the entire system, but it is often skipped in favor of its needed technology and functionality. This can lead to unforeseeable security issues. To overcome these, innovation is needed to orchestrate information while supporting the operator in keeping an overview of the security status. One way to condense security information is to correlate the relevant information and provide interpretative information. To accomplish this, a trust model can fulfill these requirements.

A trust model can provide a viable solution: It aggregates the information to summarized, condensed information and additionally identifies the cause of possible deviations in the system to bridge the gap between the abundance of data, security, and new technology. This approach proposes a trust security model to strengthen and expand security in energy systems by collecting existing (security) information and aggregating it into so-called trust facets. Additionally, it will facilitate the identification of security issues in the energy control system through the concept of tracing. Tracing uncovers the origin of an attack by identifying the key metrics that lead to a deviation in the calculated trust values.
