OT Technical Debt and Cybersecurity: A Holistic Approach to Maintenance in Industrial Environments

Operational Technology (OT) environments in industrial settings are increasingly susceptible to cyber threats. Evaluating and managing cybersecurity risks in OT is a complex task that requires integrating security considerations with other maintenance activities and improvement projects in a factory.

This blog post explores the concept of technical debt as a lens to combine cybersecurity risks with maintenance efforts in OT environments. We will discuss how to measure technical debt in OT, highlight its differences from IT technical debt, and explain how leveraging this measure can drive maintenance activities.

Finally, we will outline the benefits of this approach and provide guidance on where to start.

Evaluating Cybersecurity Risks in OT Environments

OT environments encompass a wide array of interconnected systems, making them vulnerable to cyber threats. However, assessing cybersecurity risks in isolation without considering other maintenance activities and improvement projects can lead to fragmented efforts and suboptimal results. It is crucial to adopt a holistic approach that integrates cybersecurity concerns into the overall maintenance framework.

Combining Cybersecurity Risks with Technical Debt

One effective way to combine cybersecurity risks with maintenance activities is through the lens of technical debt. Technical debt refers to the accumulated cost of compromises made during system design, implementation, and maintenance. By quantifying technical debt, organizations can prioritize and allocate resources effectively, ensuring that maintenance activities address both cybersecurity risks and other forms of technical debt.

Measuring Technical Debt in OT and Its Differences from IT

Measuring technical debt in OT involves assessing various factors unique to industrial environments. These factors include outdated hardware and software, lack of security updates, poor documentation, complex code, and integration challenges. Unlike IT technical debt, OT technical debt has immediate and tangible impacts on physical operations, safety, and compliance. It requires specialized expertise to evaluate and address.

Driving Maintenance Activities with Technical Debt

Using the measure of technical debt, organizations can prioritize maintenance activities based on their impact and urgency. By considering the severity of technical debt issues, such as security vulnerabilities and potential safety risks, maintenance efforts can be strategically directed. This approach ensures that resources are allocated to the most critical areas, reducing the overall technical debt and enhancing cybersecurity in OT environments.

The Utility of the Technical Debt Approach

The technical debt approach offers several advantages. It provides a common language and framework for stakeholders to discuss and prioritize maintenance activities, cybersecurity measures, and improvement projects. By considering technical debt holistically, organizations can align their efforts and make informed decisions based on the overall impact. This approach also facilitates better resource allocation, risk mitigation, and compliance with industry standards and regulations.

Starting Points for Addressing Technical Debt

To embark on addressing technical debt in OT environments, organizations should begin with:

a) Conducting a comprehensive assessment of OT systems and infrastructure to identify technical debt and associated cybersecurity risks.

b) Prioritizing the identified technical debt based on its severity, potential impact, and available resources.

c) Developing a roadmap that integrates cybersecurity measures and maintenance activities, while aligning with the organization's strategic goals.

d) Establishing a culture of continuous improvement, emphasizing regular evaluation, monitoring, and proactive maintenance.


In today's industrial landscape, managing cybersecurity risks in OT environments requires a holistic approach that combines maintenance activities with other improvement projects. Technical debt serves as a valuable measure to quantify and prioritize these efforts, addressing both cybersecurity risks and other forms of accumulated compromises. By leveraging the measure of technical debt, organizations can enhance the security and reliability of their OT systems, ensuring smooth operations, minimizing risks, and achieving compliance with industry standards. Initiating this approach begins with a comprehensive assessment, prioritization, and a roadmap that integrates cybersecurity and maintenance activities effectively.
