Power plants need to monitor their equipment health to ensure they are bringing the most reliable, efficient and affordable electricity to their household and business customers. However, they have long been the target of cyber attackers who seek to disrupt the energy sector supply chain. Today, electric utilities and power plants count on Fend’s data diode technology for real-time data and security that guards the grid to keep our power and economy going. Data diodes are a type of cybersecurity hardware that protects networks and other infrastructure by only allowing the data to flow in one direction.
Challenges Faced by Utilities in Network Security
What are the cybersecurity threats to utilities?
Utilities face numerous cybersecurity threats, including ransomware attacks that disrupt services and demand payment, distributed denial of service (DDoS) attacks that overwhelm systems, and advanced persistent threats (APTs) that target utilities with the intent of stealing sensitive information, disrupting services, or causing physical damage to infrastructure.
Software and hardware vulnerabilities, if not regularly updated and patched, can also leave utilities vulnerable to cyberattacks. As the threat landscape evolves and cybercriminals become more sophisticated, utilities must remain vigilant in protecting their systems and data, which is why utility cybersecurity should be a top priority for your operations.
Why is cybersecurity important for electric utilities?
Cybersecurity is crucial for electric utilities because you control the critical generation, transmission, and distribution infrastructure that supports our modern way of life. If any of these systems are disrupted or damaged due to a cyberattack, it could have devastating consequences. Successful attacks could result in data theft, service disruptions, and significant financial losses.
The increasing connectivity of devices provides more opportunities for cybercriminals to attack utilities. With this increased risk, cyber security for industrial control systems is necessary to safeguard critical infrastructure, protect public safety, and secure sensitive information from cyber threats. This can be achieved through Fend’s data diodes.
Case Study - Data Diode Solution in Action
In 2021, unexpected cold weather impacted the ability of a power generation facility in the southern US to reliably deliver electricity to thousands of customers when a critical operations piping system froze. Extreme low temperatures impacted water piping infrastructure that the power producer relied on for electric generation, destabilizing power production and posing risks to plant operations and safety. Today, the company trusts Fend’s one-way data diodes to send real-time information from previously isolated water systems to the power plant’s industrial control system (ICS) to enable plant operators to mitigate risks to the system as well as gain efficiencies through predictive maintenance. The client was able to safely integrate the operational data into its ICS while reducing threat vectors. With Fend, the client now has the real-time analytics they need to prevent operational disruption from climate impacts or 3rd party attacks and predict problems before they occur to keep the power flowing.
Benefits of Using Data Diodes for Utilities
For many years, one-way communication diodes (data diodes) were priced too high for energy suppliers. Now, the same class of technology that protects nuclear reactors and oil refineries is affordable for renewable, coal, gas and hydro-electric plants and the rest of the supply chain, allowing real-time analytics that protect the electrical grid, operational networks, and assets from climate impact and attackers. Whether you’re making upgrades to winterize your plant, improve visibility, or comply with regulations, Fend data diodes add an extra layer of physical security that blocks 100% of all inbound traffic and requires no security patches or maintenance, offering the same level of security as a physical air gap for remote access without the vulnerabilities.
Fend’s unidirectional gateway hardware physically protects you from cyberattack. Fend diodes feature:
-
All supported protocols are included with the purchase. No hidden fees or licenses.
