The digital revolution in the oil and gas industry is a two-sided coin. While the collaboration between Information Technology (IT) and Operational Technology (OT) has led to unprecedented innovation and efficiency, it has also led to increased cyber threats. This dual landscape underscores the importance of recognising that OT and IT have distinct cybersecurity requirements. OT's direct involvement with Health, Safety, & Environment (HSE) demands tailored protective measures. As the industry navigates these challenges, a thoughtful approach to cybersecurity becomes essential to safeguard critical operations and maintain a secure technological ecosystem.
The Colonial Pipeline attack in 2021 serves as an example of the industry's vulnerability to cyberattacks. These types of incidents disrupt operations and have far-reaching effects on national economies and global energy markets.
The rising incidence of cyber-attacks has made robust cybersecurity an urgent necessity. The use of advanced technologies like remote operations and AI-driven autopilot solutions has put the industry in the crosshairs of sophisticated hackers, raising the stakes for companies to implement strong security measures. According to S&P Global Platts Oil Security Sentinel, there have been 35 major cybersecurity attacks on energy and commodities infrastructure since 2017, with oil assets and infrastructure being the primary targets¹. Additionally, Statista reported that in 2022, there were 21 global ransomware attacks on the oil and gas industry, ranking it as the 5th most affected sector by ransomware in that year².
The introduction of a unidirectional flow of data by adding data diodes in between OT and IT layers is becoming increasingly crucial in protecting the industry’s network infrastructure. Data diodes offer a physical firewall against cyber invasions. This technology, when compared to standard firewalls, offers a more secure solution to safeguard critical control systems and sensitive information. Along with them, the industry is utilising other technologies like:
The average cost of a cyber breach in the industry is estimated to be around $3.7 million, resulting not only in financial losses but also long-term reputational damage.
Creating a comprehensive cybersecurity policy, conducting threat and vulnerability analysis, risk assessment, network segmentation to isolate essential systems, and employee training are pivotal for building a resilient business.
Combined with implementing various Functional Requirements (FRs) based on the Target Security Level (SL-T), having incident response plans and continuously updating security protocols ensure an advanced level of protection.
Cybersecurity consultants play a crucial role in integrating cyber defence mechanisms into digital solutions. Their expertise in understanding the OT systems, the industrial protocols, their vulnerability & risk assessment, system architectures, network architectures and their compliance to the standards is invaluable in embedding cybersecurity into the very fabric of technological solutions.
As the oil and gas industry confronts the multifaceted challenges of cybersecurity, the need for an integrated approach that combines technological innovation with expert knowledge and continuous vigilance becomes paramount.
