Navigating Cybersecurity Threats in the Utility Sector

If you’re an electric, water, gas, fiber, or other utility, you might feel like you have a target on your back. That’s because utilities are part of the critical infrastructure that powers communities, which also means they are high-profile targets for hackers and cyberterrorists. With the advancements in technology and the Internet of Things (IOT), there are more points of vulnerability. Utilities also face the challenge of constant scrutiny from regulators, which requires them to comply with IT and other security standards. Some utilities gain a false sense of security because they believe that if they comply with the minimum requirements, they’ll be adequately secure. However, the reality is that utilities must initiate proactive, robust efforts to combat cyberattacks and other threats that could compromise reliability and security.

Cyber Threats and Utilities

Cybersecurity Director Carter Manucy, at the National Rural Electric Cooperative Association (NRECA), says:

“Cyberthreats are increasing and becoming more sophisticated by the hour, and as operational costs rise, so does the cost of surviving a cyberattack.”

Recent data from Cisco backs up this assertion. Cisco’s data indicates that 73 percent of IT security professionals at utilities report having experienced a public security breach, compared with 55 percent in other industries. Because utilities are required to report when they encounter a data breach, this may partially explain the higher figure. However, this high number of public violations also indicates that the industry is vulnerable and that its comparatively high level of sophistication still needs improvement.

For example, ransomware attacks can disrupt service and demand high ransoms. They can also compromise customer information and other critical utility information. These threats, as well as those from hackers, can come from nation-state actors or domestic cyberterrorists. Vulnerabilities can also arise from third-party vendors or contractors working with the utility. Old or outdated systems can also open the utility to threats, as well as social engineering and phishing attacks targeting internal audiences.

The Million-Dollar Question

So, how can utilities protect themselves? It takes constant vigilance and proactive strategies, including detection programs, regular security audits, and incident reporting and analysis. One of the biggest challenges is the sheer number of entry points that need to be monitored. This is particularly challenging for smaller utilities which may have a small staff of IT professionals tasked with monitoring emails and all points of entry. The sheer volume of what’s being monitored is a constant and growing challenge. That’s why nearly all utilities have systems in place to detect threats, and they also have programs that train their employees to identify and report potential cyber breaches, such as phishing or social engineering attacks.

Threats in Plain Sight

Threats can also arise from unexpected places, such as former employees who still have access to your systems or physical facilities. Computer programs or forms that have been created for one specific purpose that a staff member altered to fit another purpose, PDFs authored with embedded author information. That modification may have unintended consequences, such as inadvertently exposing sensitive utility data or personally identifiable information linked to your customers. Third-party vendors who have access to your computer infrastructure and data, as well as contractors who have access to your physical buildings. With each person and point of entry, the risk increases, especially if there are weak or nonexistent monitoring mechanisms in place. Or if there are no checks and balances as to the start and end times of access. Risk can also arise from outdated or legacy systems that are more susceptible to digital attacks.

Cybersecurity is More than an IT Challenge

Cybersecurity is not just an IT challenge; it’s a human one. People are ultimately responsible for the systems, making a holistic approach essential. This involves understanding your audiences and developing a smart, flexible cybersecurity strategy. Vigilance is key, achieved through constant monitoring, implementing detection programs, providing employee training, and establishing reporting mechanisms to identify suspicious activity. Investing in IT professionals and staff who stay current with industry trends is crucial. Additionally, sharing information and strategies with other utilities and state and local government watchdogs helps keep networks safer.

Keeping your utility secure requires more than meeting the minimum standards—it demands constant vigilance, the right tools, and trusted partners who understand the stakes.
