  In the factory of the future traditional and formerly isolated Operational
Technology (OT) hardware will become connected with all kinds of networks. This
leads to more complex security challenges during design, deployment and use of
industrial control systems. As it is infeasible to perform security tests on
production hardware and it is expensive to build hardware setups dedicated to
security testing, virtualised testbeds are gaining interest. We create a
testbed based on a virtualised factory which can be controlled by real and
virtualised hardware. This allows for a flexible evaluation of security
strategies.
