Cloudifying Critical Applications: A Use Case from the Power Grid Domain

The cloud computing paradigm is gaining more and more momentum, to the extent that it is no more confined to its initial application domains, i.e. use by enterprises and businesses that are simply willing to lower costs or to increase computing capacity in a flexible manner. In particular, increasing interest is recently being paid to the dramatic potentials that the use of cloud computing technology by critical infrastructure (CI) operators might bring about, in terms of benefits for the society at large. Since accidental or deliberate damage to a CI may result in devastating consequences, this mandates for dependable and trustworthy security mechanisms in cloud platforms. In this paper, we present a distributed application for real-time monitoring of a Power Grid. The application, which is called PoGriMon, is deployed on top of the SecureCloud platform, a security-enhanced IaaS solution that exploits the Intel Software Guard eXtension (SGX) technology. PoGriMon has been designed based on the requirements of the SCADA network of the Israeli Electric Corporation (IEC), and it is currently being validated in a realistic setup also provided by IEC.
