Fortinet global survey uncovers critical challenges in operational technology

(Press Release)

Fortinet®, a global leader in broad, integrated, and automated cybersecurity solutions, has 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% (Philippines: 94%) of Operational Technology (OT) organizations 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 Fortinet report found that only 13% of respondents have achieved centralized visibility of all OT activities. Additionally, only 52% of organizations are able to track all OT activities from the security operations center (SOC). At the same time, 97% of global organizations consider OT a moderate or significant factor in their overall security risk. The report findings indicate that the lack of centralized visibility contributes to organizations’ OT security risks and weakened security posture.

 

OT security intrusions significantly impact organizations’ productivity and their bottom line.

The Fortinet report found that 93% (Philippines: 94%) of OT organizations experienced at least one intrusion in the past 12 months. The top 3 types of intrusion Philippine organizations experienced were malware, phishing email, and hacker. As a result of these intrusions, nearly 50% (Philippines: 66%) of organizations suffered an operation outage that affected productivity with 90% of intrusions requiring hours or longer to restore service. In the Philippines, 85% of OT organizations took hours and more to return to service while 4% took weeks. Additionally, one-third of global respondents saw revenue, data loss, compliance and brand-value impacted because of security intrusions.

Ownership of OT security is not consistent across organizations.

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% of global survey respondents say that the CISO holds the responsibility for OT security at their organization. In the Philippines, CEOs are getting more involved in influencing cyber security because it is becoming a bigger issue in management teams.

 

Organizations do not have full visibility into OT activities.

OT security gaps persist, with many organizations not having full visibility. The proportion of activities is centrally visible within the organization’s cybersecurity operations. In the Philippines, 88% of OT organizations that do not have complete central visibility.

 

OT security is gradually improving, but security gaps still exist in many organizations.

When asked about the maturity of their organization’s OT security posture, only 21% of global surveyed organizations 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 organizations use between two and eight different vendors for their industrial devices and have between 100 and 10,000 devices in operation, adding complexity.

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 organizations. 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, organizations’ attack surface is increasing significantly.

Best Practices to Overcome OT Security Challenges

Fortinet’s global 2022 State of Operational Technology and Cybersecurity Report indicated ways organizations can address OT systems’ vulnerabilities and strengthen their overall security posture. Organizations 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 applications without proper credentials and permissions are 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 organizations strengthen their security posture. According to Fortinet’s report, top-tier organizations–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, organizations should look to integrate their OT and IT technology across a smaller number of vendors. By implementing integrated security solutions, organizations can reduce their attack surface and improve their security posture.

 

Deploying network access control (NAC) technology.

Organizations 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, defense, manufacturing, food, and transportation. By designing security into complex infrastructure via the Fortinet Security Fabric, organizations have an efficient, non-disruptive way to ensure that their OT environment is protected and compliant. With full integration and shared threat intelligence, industrial organizations 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.
