The SDN-microSENSE intends to provide an integrated platform, which will protect the modernised Electrical Power and Energy Systems (EPES). In particular, the business logic behind SDN-microSENSE is organised by four pillars: (a) risk assessment, (b) Intrusion detection and mitigation, (c) energy grid restoration and management and (d) privacy-preserving. The first pillar follows a collaborative risk assessment methodology, which is applied dynamically by the SDN-microSENSE Risk Assessment Framework (S-RAF), taking into account the relevant EPES standards. The second pillar detects and mitigates potential intrusions against EPES, taking full advantage of the Software-Defined Networking (SDN) technology and islanding mechanisms. The third pillar aims to assist in restoring the electrical grid after the successful treatment of the cyberattacks. Finally, the last pillar deals with the privacy of the involved EPES entities, employing homomorphic encryption.
