As the electric power industry upgrades older, outdated infrastructure to take advantage of emerging technologies, utilities are also moving towards greater information technology (IT) and operational technology (OT) convergence. This allows greater numbers of technologies, devices, and systems to connect to the grid to improve efficiency, provide access to data normally held in silos, and enhance productivity.
One such area that touches a utility's IT and OT departments is identity and access management. Many utilities run identity and access management (IdAM) systems that are decentralized and controlled by numerous departments. Several negative outcomes can result from this: an increased risk of attack and service disruption, an inability to identify potential sources of a problem or attack, and a lack of overall traceability and accountability regarding who has access to both critical and noncritical assets.
To help the energy sector address this cybersecurity challenge, security engineers at the National Cybersecurity Center of Excellence (NCCoE) developed an example solution that utilities can use to more securely and efficiently manage access to the networked devices and facilities upon which power generation, transmission, and distribution depend. The solution demonstrates a centralized IdAM platform that can provide a comprehensive view of all users within the enterprise across all silos, and the access rights users have been granted, using multiple commercially available products.
Electric utilities can use some or all of the guide to implement a centralized IdAM system using NIST and industry standards, including North American Electric Reliability Corporation's (NERC) Critical Infrastructure Protection (CIP). Commercial, standards-based products are easily available and interoperable with commonly used information technology infrastructure and investments.
