Power Sector Cybersecurity Building Blocks

Upcoming Webinar Announcement: 

Register today for the next webinar in this series on November 17, 2021, at 11:00 a.m. EDT, 12:00 p.m. AST, 3:00 p.m. GMT.

Can utilities synchronize external compliance efforts with internal controls to maximize cybersecurity? This webinar will bring together a diverse set of stakeholders and subject matter experts to discuss compliance — the effort within a utility to remain in compliance with applicable laws, regulations, and standards.

The Power Sector Cybersecurity Building Blocks, developed through the U.S. Agency for International Development (USAID)-National Renewable Energy Laboratory (NREL) Partnership and the Partnership’s Resilient Energy Platform, are designed to help a variety of stakeholders improve security for the electrical grid. This effort grows out of USAID and NREL’s discussions with utilities around the world, as well as past cybersecurity assessments performed by NREL on dozens of utilities and government agencies, with a focus on the cybersecurity challenges faced by small and under-resourced utilities.


Note: Solid color blocks are internal to the utility; shaded blocks are external to the utility.

The building blocks function as a guide to help organizations develop a robust cybersecurity defense program. Individually, each building block represents a cluster of related activities within cybersecurity on which an organization should focus. Using the building blocks, organizations can effectively prioritize their cybersecurity efforts to best thwart a wide range of potential cyberattacks.

The 11 Cybersecurity Building Blocks each discuss a particular element of a well-rounded cybersecurity framework:

  • Governance: The processes that direct a utility-wide cybersecurity effort and provide accountability for that effort. Cybersecurity governance requires the understanding and action of those at the very top level of the utility, such as the executive director, chief executive officer, board of directors, and others.
  • Organizational Security Policy: This building block focuses on the high-level document that captures the essential elements of a utility’s efforts in cybersecurity and includes the effort to create, update, and implement that document.
  • Risk Management: Activities that identify and evaluate cybersecurity risk, with the goal of reducing that risk to a level appropriate to the utility’s business objectives.
  • Cyber Threat Intelligence: Cyberattack tools and adversaries that might constitute a threat and the vulnerabilities they could exploit. Utilities need CTI to understand the threat landscape and take action to mitigate cyber risks.
  • Laws, Regulations, and Standards: Laws and regulations are the compulsory host country directives that a utility must comply with regarding cybersecurity. Regulations sometimes enforce standards created by nongovernmental entities that capture best practices.
  • Compliance: The effort within a utility to remain in compliance with laws, regulations, and standards.
  • Procurement: The processes used to monitor and improve the cybersecurity of devices, applications, and services as they are acquired and integrated into utility operations, as well as efforts to manage supply chain risk.
  • Technical Controls: The hardware and software components that protect a system against cyberattack. Firewalls, intrusion detection systems (IDS), encryption, and identification and authentication mechanisms are examples of technical controls.
  • Incident Response: The actions taken by a utility to prepare for cyberattacks. This includes creating plans for response, rehearsing the response prior to an attack, continuous monitoring to identify attacks, and the actual response.
  • Cybersecurity Awareness Training: Steps taken by utilities to educate all employees (including nontechnical staff) about potential cyber threats and their roles in preventing them.
  • Workforce Development: The efforts by multiple organizations, such as government, industry, or academia, to ensure an adequate supply of workers with specialized cybersecurity knowledge and skills

The Need

There are already many excellent guides, standards, and frameworks for organizations seeking to improve cybersecurity. Some are produced by standards bodies, such as the International Organization for Standardization. Others are produced by government agencies, such as the United States National Institute of Standards and Technology (NIST). Equipment vendors, consultants, and nonprofits have also created useful resources.

However, many organizations still struggle to create a cybersecurity program that is balanced across all areas required to protect their assets from attack. They may have heavy investments in one area, with little investment in another. For these organizations, the “building block” approach will hopefully prove useful. The building blocks define clusters of related activities within a balanced cybersecurity program and provide references and resources for each area. Since the building blocks correspond to activities, staff time and resources need to be allocated to them in the same way that staff time and resources are allocated to noncyber activities (such as accounting). The clusters of related activities defined by the Power Sector Cybersecurity Building Blocks span multiple stakeholders. Organizations in the early stages of cybersecurity maturity will likely get the most benefit from these building blocks because they are likely to struggle with the question of what a complete cyber program looks like. More “cyber mature” organizations can also use the building blocks to gain a fresh perspective on their efforts and fill in gaps in their existing cyber programs.

The Power Sector Cybersecurity Building Blocks are not meant to be the final word on cybersecurity for the power sector, as this field is evolving rapidly with the introduction of new power grid technology and an ever-changing threat landscape. USAID and NREL welcome discussion regarding updates to future iterations of these building blocks. For more information, please read the full report.


Ongoing Cybersecurity Building Blocks Webinar Series

USAID and NREL are partnering with CARILEC to offer a series of webinars based upon the Power Sector Cybersecurity Building Blocks. Each webinar offers a deep dive into the many issues utilities face when building a balanced cybersecurity plan to thwart attacks, minimize impacts, and get back to business quickly following an incident.
