Full user access logging and recording.Securing remote OT access requires a zero-trust framework that mitigates risk without significantly undermining usability. To empower hybrid teams with OT operational capacity without undermining cybersecurity, utilities can develop resilience by pursuing usability and cybersecurity in tandem and without compromise. Although the ransomware attack impacted the company’s IT assets, it was forced to halt operations because of ineffective segmentation and cybersecurity controls. Most recently, a cyber attack on Colonial Pipeline, an essential utility providing 45% of the East Coast’s fuel, cost the company more than $4 million and resulted in long-lines and panic buying at local gas stations. Failure to secure these networks effectively can have significant consequences for companies and their customers. Increasing automation and the proliferation of Industrial Internet of Things (IioT) technology have created interdependencies between critical IT systems and OT networks. Meanwhile, OT networks are comprised of physical control systems, where downtime can put public safety at risk or create ripple effects through the wider economy. These data-heavy digital assets require IT and cybersecurity teams to direct their efforts accordingly, working with hyper-focused precision to secure company and customer data. In response, utilities need to secure their OT remote operations with solutions that combine resiliency, security and affordability.Ī utility’s IT network is multifaceted, connecting billing departments, accounting professionals and human resources personnel. However, when not adequately protected, these systems create cybersecurity vulnerabilities that put people, profit and critical resources at great risk. In other words, engaging and operating infrastructure using OT resources empowers teams to work effectively from anywhere in the world.
Most importantly, according to a survey of 1,726 utility professionals, cybersecurity challenges are amplified as utilities connect OT assets to existing IT systems. While this presents unique opportunities to curb expenses while boosting certain capabilities, it also presents novel cybersecurity challenges that utilities can’t ignore. Moving forward, it’s clear that hybrid teams composed of remote and on-site employees will become more common among utilities. The recent pandemic radically reoriented public utilities as they empowered remote and hybrid teams to maintain operational continuity in any environment.
