In the world of Operational Technology (OT) and Industrial Control Systems (ICS), security cannot rely on a “set it and forget it” mindset or an over-reliance on the latest shiny technology. Many organizations fall into the trap of looking for a quick fix, thinking a single tool will solve their cybersecurity challenges. Spoiler alert: it won’t.

The Foundation: Sound Security Fundamentals

Before investing in technology, it’s critical to conduct a comprehensive security assessment using an appropriate framework for your organization (e.g., NIST CSF/CPGs/800-82/800-53, IEC 62443, CIS Controls, etc.). This assessment helps identify gaps, clarify risk appetite, and establish a unified view of risk—essential steps for integrating OT/ICS risks into an Integrated Risk Management (IRM) to eliminate the silos between IT/OT and other systems to feed into the business’s Enterprise Risk Management (ERM) strategy.

Governance Matters

Strong governance is the backbone of effective security programs. It ensures “one throat to choke,” aligning responsibility and accountability at every level. With a clear governance structure, businesses can align their strategic plans, update policies, and embed Security and Risk Management practices into their operations.

The Bigger Picture: Why GRC Exists

Remember the roots of Governance, Risk, and Compliance (GRC).

Born out of scandals like Enron and Arthur Andersen, GRC safeguards business integrity. It safeguards organizations by creating a culture of accountability, managing risks holistically, and ensuring compliance that supports business innovation and growth.

By embedding GRC, organizations build a resilient, ethical, and efficient framework that can adapt to the ever-changing business and regulatory environment.

Today, it plays a vital role in OT/ICS security:

• Foundation for Strategic Oversight
• Translating technical risks into actionable business insights
• Guiding long-term security strategy that supports business objectives.
• Aligning Business Objectives with Risk Management
• Enhancing Operational Efficiency
• Supporting Regulatory Compliance
• Strengthening Risk Management
• Enabling Informed Decision-Making
• Building Trust and Protecting Reputation
• Promoting Resilience and Business Continuity

Security isn’t a product; it’s a process. By focusing on assessments, sound fundamentals, and strategic oversight, organizations can build a resilient security program—not just pass audits.
