Fortinet's study on Singapore's operational technology (OT) sector illustrates the state of cybersecurity awareness among local organisations and the importance of securing OT environments.

The study found that cyber security Intrusion impacted more than 9 out of 10 OT organisations surveyed in Singapore, and about 88% of them lost data and suffered operational outages affecting productivity.

Moreover, 94 percent of organisations also indicated that they do not have complete visibility within their cybersecurity operations, which means they are unaware of the threats in their networks. Ransomware emerged as the biggest concern, with 64% of the respondents having a high level of concern compared to
other intrusions.

Singapore has been investing in securing operational technology through training cybersecurity professionals and the OT Cybersecurity Competency Framework, as highlighted by Minister for Communications and Information Mrs Josephine Teo.

"We believe enhanced collaboration between the public and private sectors, supported by suitable security tools investments, will better position Singapore to manage future OT cyber-attacks. "

John Maddison, EVP of Products and CMO at Fortinet says, “This year’s global State of OT and Cybersecurity Report demonstrates that while OT security has the attention of organisational leaders, critical security gaps remain. PLCs designed without security, continued intrusions, a lack of centralized visibility across OT activities, and growing connectivity to OT are some of the critical challenges these organisations need to address.

Operational Technology infrastructure

"Security converged into the OT networking infrastructure, including switches and access points and firewalls, is essential to segment the environment. This combined with a platform that spans OT, converged OT/IT and IT provides end-to-end visibility and control.”

Fortinet^®, a global leader in broad, integrated, and automated cybersecurity solutions, today released its global 2022 State of Operational Technology and Cybersecurity Report.

While industrial control environments continue to be a target for cybercriminals – with global: 93% (Singapore: 86%) of Operational Technology (OT) organisations experiencing an intrusion in the past 12 months – the report uncovered widespread gaps in industrial security and indicated opportunities for improvements. Key findings of the report include:

  • OT activities lack centralized visibility, increasing security risks. The global Fortinet report found that only 13% (Singapore: 12%) of respondents have achieved centralized visibility of all OT activities. Additionally, only 52% of organisations are able to track all OT activities from the security operations centre (SOC). At the same time, 97% of global organisations consider OT a moderate or significant factor in their overall security risk. The report findings indicate that the lack of centralized visibility contributes to organisations’ OT security risks and weakened security posture.
  • OT security intrusions significantly impact organisations’ productivity and their bottom line. The Fortinet report found that 93% (Singapore: 86%) of OT organisations experienced at least one intrusion in the past 12 months. The top 3 intrusion types of Singaporean organisations experienced were phishing emails, malwares, and hackers. As a result of these intrusions, nearly 50% (Singapore: 86%) of organisations suffered an operation outage that affected productivity with 90% of intrusions requiring hours or longer to restore service while 88% of Singaporean OT organisations took up to a few hours to return to service and the rest of 12% took days, weeks, months, respectively. Additionally, one-third of global respondents saw revenue, data loss, compliance and brand value impacted as a result of security intrusions.
  • Ownership of OT security is not consistent across organisations. According to the Fortinet report, OT security management falls within a range of primarily director or manager roles, ranging from the Director of Plant Operations to Manager of Manufacturing Operations. Only 15% (Singapore: 4%) of survey respondents say that the CISO holds the responsibility for OT security at their organisation.

  • OT security is gradually improving, but security gaps still exist in many organisations. When asked about the maturity of their organisation’s OT security posture, only 21% of organisations have reached level 4, which includes leveraging orchestration and management. Notably, a larger proportion of Latin America and APAC respondents have reached level 4 compared to other regions. The report found that a vast majority of organisations use between two and eight different vendors for their industrial devices and have between 100 and 10,000 devices in operation, adding complexity. For Singapore, the report found that 88% of Singaporean OT organisations have between 1,000 – 10,000 IP-enabled OT devices in operations. Local organisations face challenges with using multiple OT security tools, further creating gaps in their security posture.

OT Security is a Corporate-Level Concern

As OT systems increasingly become targets for cybercriminals, C-level leaders recognize the importance of securing these environments to mitigate risks to their organisations. Industrial systems have become a significant risk factor since these environments were traditionally air-gapped from IT and corporate networks, but now these two infrastructures are becoming universally integrated. With industrial systems now being connected to the internet and more accessible from anywhere, organisations’ attack surface is increasing significantly.

With the IT threat landscape becoming more sophisticated, connected OT systems have also become vulnerable to these growing threats. This combination of factors is moving industrial security upward in many organisations’ risk portfolio. OT security is a growing concern for executive leaders, increasing the need for organisations to move toward full protection of their industrial control system (ICS) and supervisory control and data acquisition (SCADA) systems.

Best Practices to Overcome OT Security Challenges

Fortinet’s global 2022 State of Operational Technology and Cybersecurity Report indicated ways organisations can address OT systems’ vulnerabilities and strengthen their overall security posture. Organisations can address their OT security challenges by:

  • Establish Zero Trust Access to prevent breaches. With more industrial systems being connected to the network, Zero Trust Access solutions ensure that any user, device or application without proper credentials and permissions is denied access to critical assets. To advance OT security efforts, Zero Trust Access solutions can further defend against both internal and external threats.
  • Implementing solutions that provide centralized visibility of OT activities. Centralized, end-to-end visibility of all OT activities is key to ensuring organisations strengthen their security posture. According to Fortinet’s report, top-tier organisations – which make up the 6% of respondents who reported no intrusions in the past year – were more than three times as likely to have achieved centralized visibility than their counterparts who suffered intrusions.
  • Consolidating security tools and vendors to integrate across environments. To remove complexity and help achieve centralized visibility of all devices, organisations should look to integrate their OT and IT technology across a smaller number of vendors. By implementing integrated security solutions, organisations can reduce their attack surface and improve their security posture.
  • Deploying network access control (NAC) technology. Organisations that avoided intrusions in the past year were more likely to have a NAC in place, ensuring that only authorized individuals can access specific systems critical for securing digital assets.

Securing OT Environments with the Fortinet Security Fabric

For more than a decade, Fortinet has protected OT environments in critical infrastructure sectors such as energy, defence, manufacturing, food, and transportation. By designing security into complex infrastructure via the Fortinet Security Fabric, organisations have an efficient, non-disruptive way to ensure that their OT environment is protected and compliant.

With full integration and shared threat intelligence, industrial organisations gain fast, automated responses to attacks in any vector. Fortinet’s Security Fabric covers the entire converged IT-OT network to close OT security gaps, deliver full visibility and provide simplified management.
