Smart power grid security services: Risk management approach considering both OT and it domains case study: Shiraz Power Distribution company

Now a day, many progresses in both Information Technology and Power System Operation domains lead to outspread their applications in power distribution systems. Convergence of utility business information technology (IT) and power system operation technology (OT) are bringing new protocols, analysis and performance challenges for interoperable end to end security risk management systems. Unified risk management approaches are critically needed to effectively guide resource allocations, identify best practices on the basis of practical and meaningful benchmarks and demonstrate various regulatory and business compliances for both the control systems and business domains. Implement an appropriate security system on the network has the advantage that at any time, depending on the alert, network will go to a secure position in terms of both topology and information system. This paper presents essential characteristics and properties for security risk management approaches in the context of the smart power grid. The work is typically illustrated using the network architecture of Shiraz Power Distribution System.
