The cybersecurity landscape has undergone significant transformations over the years, with an increasing emphasis on protecting industrial control systems (ICS) and operational technology (OT) environments. The growing threat of cyber-attacks on critical infrastructure, including power grids, oil and gas processing facilities, heavy manufacturing plants, food and beverage processes, and water management facilities, highlights the need for tailored cybersecurity strategies and controls.
The rapidly evolving domain of cybersecurity presents distinct challenges and needs for ICS/OT security, which differ from traditional IT security. ICS/OT engineering systems require specialized threat detection and visibility capabilities to protect against sophisticated cyber-attacks that can cause irreversible physical damage to critical engineering assets. Recent incidents, such as TRISIS, CRASHOVERRIDE, Pipedream, and Fuxnet, demonstrate the evolution of cyber threats from mere nuisances to potentially catastrophic events, orchestrated by state-sponsored groups and cybercriminals.
These actors target not only financial gains but also disruptive outcomes and acts of warfare, blending cyber and physical attacks. Human-operated ransomware and targeted ICS/OT ransomware pose concerns being on the rise in recent times. The increasing sophistication and frequency of these attacks underscore the need for effective cybersecurity controls and a dedicated budget.
A recent survey conducted by SANS in 2024 revealed that only 31% of respondents have a SOC (Security Operations Center) that includes capabilities specific to ICS/OT, which is crucial for effective incident response and ongoing system monitoring. This alarming statistic highlights the critical disconnect between ICS/OT security needs and traditional IT security approaches.
The threat landscape has changed due to interconnectivity, with IT networks and the Internet introducing significantly higher risks to connected ICS/OT environments than the risks ICS/OT and engineering environments had a few decades ago. Data from the 2024 SANS State of ICS/OT Cybersecurity Report indicate that 46% of attacks on ICS/OT environments are sourced from a compromise in IT support networks that allow threats into ICS/OT, impacting networks and operations.
This is concerning given the complex nature of ICS threats and the severe multi-sector cascading impacts that may result from a coordinated engineering cyber-attack in a vital critical infrastructure sector. Attacks on ICS/OT can have serious consequences to the environment, and to the safety of people.
In light of these findings, it is essential to reevaluate ICS/OT risks, impacts, budgets, and controls to protect what makes an ICS organization a business – the engineering and operating technology systems. Organizations and utilities must align security expenditures with critical functions that drive business in ICS organizations and critical infrastructure, specifically focusing on operational technologies at Purdue Levels 1 to Level 3.5.
By realigning security budgets with these specific needs, organizations can enhance security to operate more safely and efficiently in today's ICS/OT cyber threat landscape. Moreover, leadership and tactical analysts in ICS/OT critical infrastructure sector utilities must verify and/or implement the threat-driven prioritized SANS Five ICS Cybersecurity Critical Controls.
Furthermore, attending courses such as ICS515 – a 6-day technical ICS/OT incident response and visibility training – can provide practitioners with hands-on workshop and ICS/OT security training. Industry peers, SANS expert instructors, and practitioners will connect at the 20th Annual ICS Security Summit in Orlando this coming June 15-17.
In conclusion, the critical disconnect between ICS/OT security needs and traditional IT security approaches demands attention from organizations, utilities, and policymakers alike. By recognizing the unique operational missions, risk surface, and safety consequences of cyber incidents that impact the physical world, we can develop effective cybersecurity strategies and controls tailored to ICS/OT environments.
