Abstract
The regional electricity grid is a central and vital component in any national electricity distribution. This grid consist of multiple cyber-physical systems (CPS) and hence is prone to attacks against any of these components, and has in some occurrences been compromised with devastating effects. As the electricity sector has started focusing more on easier controlling, monitoring and in general improving control systems, new technologies will be mixed with the old, legacy systems, mainly implementing the standard TCP/IP stack for these kind of operations. This in turn leads to integration with managerial systems for reporting, which in turn leads to the potential of exposing a critical infrastructure for cyber attacks. In this thesis, focus will be put on building a lab where attacks against the remote controlling and operations of a regional electricity grid can be performed, and, in time, how a variety of attacks will affect the stability of the regional power grid, potentially revealing how such an attack can affect the delivery of such a critical infrastructure. The result will give a detailed overview of how a simulated environment can be built and a set of attack scenarios that can be reproduced to see what effect the various attacks can have on a real system, building a baseline for a lab environment for further development.
