How Hardware Encryption Fuels Cyber Resilience in the Energy Sector
It's not just about compliance. It's about pragmatism.
The importance of protecting energy infrastructure from cyberattack can't be stressed enough. When a brief outage can deliver a major impact on the community it serves, a prolonged outage can spell disaster. Major public works remain prime targets for cyber criminals. As ransomware, espionage, and insider threats intensify, energy organizations must not only strengthen their defenses, but have a strategy in place to quickly and fully restore operations in the wake of a cyber event. It's not just a matter of compliance but a matter of adopting a zero-trust stance where the assumption of imminent cyber attack persists at all times. In short, It's not a matter of IF, but WHEN.
This paper explains why data‑at‑rest protection is a “first control” for mixed IT/OT environments, why hardware‑based encryption is the most reliable way to secure removable media and field workflows, and how Apricorn devices help teams meet today’s standards while preparing for tomorrow’s. You’ll find a compliance chart and real‑world use cases for utilities, pipelines, and renewables.
The Expanding Threat Landscape
Building on the executive summary: as global electricity demand and interconnections surge in 2025, system reliability increasingly hinges on how well we protect the data that moves between IT and OT. From refineries to renewable plants, no energy subsector is immune to cyber risk. The Colonial Pipeline ransomware attack in 2021 exposed the vulnerabilities of interconnected OT and IT systems. More recently, advisories from U.S. cyber authorities highlight increased targeting of programmable logic controllers (PLCs), substation management systems, and remote access terminals. As energy systems digitize, they also expand their attack surfaces—making encryption a non‑negotiable control for protecting critical data.
The Real Cost of Inaction
Independent breach research places the 2025 average breach cost near $4.88 million, with energy and utilities often higher due to regulatory scrutiny and downtime. Beyond direct costs, compromised data can endanger physical infrastructure, impact reliability, and erode public trust.
Why Hardware Encryption is the Right Choice for Protecting Data
Energy data moves constantly—between control centers, field teams, and vendors. Each transfer introduces risk. Hardware encryption isolates security functions from vulnerable operating systems, ensuring that sensitive data remains encrypted even if the host is compromised. It’s a vital safeguard for protecting data at rest—the state where many breaches begin.
Benefits of Hardware Encryption:
-
- Encrypts data on the device, independent of any software.
- Aligns with FIPS 140‑2 / 140-3 validation to support DOE, NERC, and federal standards
- Deters tampering with PIN‑authenticated, tamper‑evident designs that prevent unauthorized access or manipulation.
- Minimizes key‑exposure risk by eliminating reliance on software‑based encryption methods.
Regulatory Drivers for Encryption in Energy
- Aligns to NERC CIP: CIP‑011 and CIP‑013 mandate data protection and supply chain security; encrypted, policy‑enforced media help utilities demonstrate compliance.
- Reinforces TSA Pipeline Security Directives: Secure data handling, segmentation, and incident recovery using removable media controls.
- Embeds DOE Cyber‑Informed Engineering (CIE): Build cyber resilience into system design—hardware‑encrypted storage as a foundational element.
- Establishes FIPS 140‑2 / 140-3 (Sept 2026) --the NIST standard for cryptographic modules used across federal and energy‑sector systems--as the current benchmark.
