Software-Defined Network (SDN) is a network architecture which decouple network control and forwarding functions, enabling network control to become directly programmable. The SDN paradigm can bring new opportunities to en- hance security of power grid communication and SCADA/EMS networks, of- fering new approaches for preventing, detecting and mitigating cyberattacks. Based on this reality, the SDN-microSENSE project intends to provide a set of secure, privacy-enabled and resilient to cyberattacks tools, thus ensuring the normal operation of EPES. During the pilot massive false data injection attack will be launched concurrently against SCADA/EMS system, that will target the data integrity. The main objective of the pilot is tovalidate the SDN microSENSE platform in the operational environment of the Bulgarian grid operator.
