Announcement
The NCCoE has released a draft the latest NIST Cybersecurity Practice Guide 1800-2, Identity and Access Management for Electric Utilities, and invites you to download the draft and provide feedback.
The electric power industry is upgrading older, outdated infrastructure to take advantage of emerging technologies, but this also means greater numbers of technologies, devices, and systems connecting to the grid that need protection from physical and cybersecurity attacks. Additionally, 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 engineeres 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, like the ones we used, are easily available and interoperable with commonly used information technology infrastructure and investments.
To protect power generation, transmission, and distribution, energy companies need to control physical and logical access to their resources, including buildings, equipment, information technology, and industrial control systems. They must authenticate authorized individuals to the devices and facilities to which they are giving access rights with a high degree of certainty. In addition, they need to enforce access control policies (e.g., allow, deny, inquire further) consistently, uniformly, and quickly across all of their resources. This project resulted from direct dialogue among NCCoE staff and members of the electricity subsector, mainly from electric power companies and those who provide equipment and/or services to them. The goal of this project is to demonstrate a centralized, standards-based technical approach that unifies identity and access management (IdAM) functions across operational technology (OT) networks, physical access control systems (PACS), and information technology systems (IT). These networks often operate independently, which can result in identity and access information disparity, increased costs, inefficiencies, and loss of capacity and service delivery capability. This guide describes our collaborative efforts with technology providers and electric company stakeholders to address the security challenges energy providers face in the core function of IdAM. It offers a technical approach to meeting the challenge, and also incorporates a business value mind-set by identifying the strategic considerations involved in implementing new technologies. This NIST Cybersecurity Practice Guide provides a modular, open, end-to-end example solution that can be tailored and implemented by energy providers of varying sizes and sophistication. It shows energy providers how we met the challenge using open source and commercially available tools and technologies that are consistent with cybersecurity standards. The use case scenario is based on a normal day-to-day business operational scenario that provides the underlying impetus for the functionality presented in the guide. While the reference solution was demonstrated with a certain suite of products, the guide does not endorse these products in particular. Instead, it presents the characteristics and capabilities that an organization’s security experts can use to identify similar standards-based products that can be integrated quickly and cost-effectively with an energy provider’s existing tools and infrastructure.
