2021 State of Operational Technology and Cybersecurity Report
Rajesh Maurya Regional Vice President, India & SAARC, Fortinet The 2021 State of Operational Technology and Cybersecurity Report from Fortinet finds that operational technology (OT) leaders continue to face cybersecurity challenges, some of which were exacerbated by the shift to work from home due to the pandemic. The pandemic also accelerated IT-OT network convergence for most organizations, which correlates to other CEO reports that indicate that pandemic-related changes have accelerated digital transformation, putting organizations years ahead of where they would have expected to be at this point. Many organizations had to increase their technology budgets to accommodate the move to remote work. And as a result of the many changes brought about by the pandemic, many OT leaders are looking for new ways to streamline processes and reduce costs. As noted in the 2020 report, the momentum for OT-IT network convergence was already happening pre-pandemic, but the effects of the pandemic accelerated digital transformation and increased the need for connectivity. Employees were required to work from home and OEMs and system integrators were hampered by their inability to travel to service equipment. Getting on-site became much more difficult, so the pandemic clearly increased the need for third-party secure remote access. Overcoming these challenges increased both costs and risks. In 2021, we saw a change in respondents away from manager of manufacturing to more VP and director level. The responsibility for OT is shifting away from VP or Director of network engineering to CISOs and CIOs. Additionally, there were more security operations centers (SOCs) and significantly more network operations centers (NOCs) in place in 2021 than the prior year. As we have in previous years, we also compared the practices of respondents who had seen zero intrusions in the past year with those who had 10 or more intrusions. We again found that ‘top-tier’ OT leaders were significantly more likely to adhere to a number of best practices, including: Leveraging orchestration and automation and using predictive behavior. Tracking and reporting the financial implications of cybersecurity to the business. Reporting compliance with industry regulations and scheduled security assessments. Adhering to cybersecurity best practices helped top-tier OT organizations better withstand the technology changes, threats, and vulnerabilities that occurred during the pandemic. METHODOLOGY FOR THIS STUDY This year’s State of Operational Technology and Cybersecurity Report is based on a survey conducted from February 24 to March 1, 2021. The questions mirrored those asked in similar surveys in 2019 and 2020. Respondents work at companies involved in four industries: manufacturing, energy and utilities, healthcare, and transportation. All are responsible for some aspect of manufacturing or plant operations and occupied job grades ranging from manager to vice president. This study utilizes data from the survey to paint a picture of how operations professionals interact with cybersecurity in their daily work. The analysis looks at this year’s data and compares it with results from prior years and identifies several overarching insights about the state of the industry. We then delve more deeply into the data, identifying best practices more commonly used by ‘top tier’ organizations – those who have experienced 0 intrusions in the past 12 months versus those that have seen more than 10 attacks in the same period. INTRODUCTION The operational technology (OT) market is expected to continue to grow through 2027 at a CAGR of 6.40%, which is no surprise because OT makes it possible for the world’s factories, energy production and transmission facilities, transportation networks, and utilities to function. To boost operational efficiency and profitability, many OT companies have been integrating OT infrastructure such as supervisory control and data acquisition (SCADA) systems with IT networks. Competitive pressures are driving an urgency to reduce costs and increase efficiencies in a variety of ways such as: Utilizing digital twins to reduce risks supporting asset performance management (APM). Increasing overall equipment effectiveness (OEE) to drive increased manufacturing yield. Shifting from calendar-based to condition-based maintenance to minimize lost production associated with service outages. Increasing asset availability and reliability. Digitization of paper record-keeping and service reports for service and maintenance activities. These and other digital transformation initiatives have led to innovations requiring new platforms and new ways for people to work than they have in the past. That change in workstyles was exacerbated with the sudden need for employees to work from home. Although the move to remote work is a significant example of digital transformation, the array of systems and processes affected as a business digitally innovates spans all of OT. All the improved agility and efficiency that comes from OT-IT network convergence also comes with increased risks. The diminishing presence of the ‘air gap’ between OT net works and IT systems means the OT infrastructure is subject to all of the threats that IT systems have traditionally faced. Worse, the attack surface for an OT system can comprise Industrial Internet of Things (IIoT) devices, which control critical systems that can have potentially dire health and safety consequences if they are breached. A majority of OT leaders report the maturity of their security posture as at least Level 2 access, which means they have established visibility, segmentation, access, and profiling. At Level 2, they have complete role-based access and are working to achieve zero trust by enforcing multi-factor authentication. In fact, 99% of surveyed respondents were above Level 0, which means only 1% have absolutely no visibility or segmentation in place in OT. Although progress is being made, there is room to grow. Most OT organizations are not leveraging orchestration and automation and their security readiness was further taxed by the COVID-19 crisis. OT-IT network convergence coupled with an ever increasing advanced threat landscape and coping with pandemic-related issues made it even more difficult for OT leaders to stay ahead of adversaries. Although following security best practices takes time and money, those organizations that did were better able to withstand the changes brought about by the pandemic. INSIGHTS FOR OT SECURITY As noted, OT leaders continued to struggle with changes related to OT-IT convergence. Additionally, the…
