Secure ICCP IntegrationConsiderations and Recommendations

The goal of this report is to identify the operation and implementation issues associated with the introduction of the secure form of the Inter-control Center Communications Protocol, or ICCP, formally referred to as IEC 60870-6-TASE.2, into the utility infrastructure. The report provides considerations and recommendations to assist a utility owner to advance the security of the utility’s data exchange operations. The report starts with a description of information assurance, and then discusses end node authentication and Public Key Infrastructures (PKI) using Certificate Authority (CA) certificates. Network infrastructures and protocols associated with ICCP are reviewed, assessed, and modeled to identify the impact of these structures and protocols to the efficient delivery of ICCP data. The report highlights certificate management and implementation issues and discusses some of the transitional issues and strategies to overcome security limitations during the introduction phase of Secure ICCP. Finally the report provides some performance measurement data of the configuration impacts of using security layers to provide Secure ICCP implementations.
