Secure Remote Access in Critical Infrastructure Environments

secure remote access in critical infrastructure environments

Power X, a large energy conglomerate, allows remote employees and contractors to access company systems via a Virtual Private Network (VPN). The company’s technical team would prefer on-site access only, but they learned quickly during the COVID-19 pandemic that such security precautions seemingly hinder business continuity.

Joe Johnson works for a third-party vendor that contracts with Power X. He oversees software updates for a specific Supervisory Control and Data Acquisition (SCADA) system, which monitors and controls power transmission and distribution of one of Power X’s largest subsidiaries.

While Joe is on vacation in Costa Rica, he remembers that he forgot to tell Bob, his coworker, about a specific patch upgrade available today. It’s not a big undertaking, so Joe decides to do it himself. He connects to the hotel Wi-Fi, immediately logs into the Power X VPN, completes the upgrade, and then heads to the beach.

Joe doesn’t realize that he has just fallen victim to a Man-in-the-Middle Attack (MitM). The hotel Wi-Fi that seemed legitimate was not. Instead, it was a fake hotspot created by a local hacker to collect passwords and other data from unsuspecting tourists. In the minute it took for Joe to connect to the VPN, the attacker gained access to Joe’s keystrokes, log files, and more. The hacker now has all he needs to exploit any weakness in Power X’s VPN – and negatively impact millions of Americans.


The Remote Access Balancing Act in Critical Infrastructure

Power X serves millions of customers across the United States through its subsidiaries. These companies offer a variety of energy resources, including natural gas, carbon-free nuclear, solar, wind, and more. Power X knows that regardless of the resource, its customers are looking for them to “keep the lights on” with affordable, clean, and reliable energy.

Power X is just one example of an organization within the critical infrastructure industry. Critical infrastructure companies provide essential assets, such as water, electricity, transportation, and healthcare, to the masses. Without just one of these assets, society as we know it would change forever.

While there is no Joe and no Power X in real life, the example above illustrates the importance of secure remote access in modern critical infrastructure environments. Companies must embrace the efficiencies of distributed workforces while safeguarding their systems' confidentiality, availability, integrity, authenticity, and non-repudiation.

VPNs have vulnerabilities. Alone, they cannot ensure secure remote access to any environment – let alone a critical infrastructure one. As a result, organizations like Power X need comprehensive, future-proof security strategies to meet today’s remote access challenges.
