De-Risking Operational Technology: 5 Security Investments That Deliver Disproportionate Returns

Webinar Highlights 

The convergence of business networks and industrial control systems has created unprecedented hybrid environments. Today, mid-market manufacturing companies face significant challenges as the economic drive for remote diagnostics and integrated supply chains forces these systems together. This shift introduces immense technical friction. Traditional security tools designed to protect corporate laptops fail spectacularly when applied to programmable logic controllers and safety instrumented systems.

Data from the Cybersecurity and Infrastructure Security Agency clearly shows that adversaries are not relying on highly advanced, theoretical exploits. They are simply walking through open doors. Rebuilding true defence in depth for critical infrastructure requires abandoning the illusion of a secure perimeter and assuming the internal network is already hostile.

To actively address these vulnerabilities, we must distill industrial cyber security into five distinct, orthogonal dimensions. These represent specific vectors to invest in, measure against, and continuously improve. The most crucial aspect of these five dimensions is that they are orthogonal, meaning they mitigate different risks using entirely independent mechanisms.

Consider the Swiss cheese model of defence in depth. Every defensive layer has inherent flaws. If you stack multiple layers of the exact same defence, the vulnerabilities align, allowing a threat to pass straight through your environment. However, if you implement orthogonal defences, a failure in one specific layer does not result in a systemic breach. This is similar to the concept of multi-factor authentication, where you combine uncorrelated risks. A criminal who purchases a database of stolen passwords does not possess your physical hardware token.

In this educational webinar, we will translate complex global standards, such as NIST SP 800-82 and ISA/IEC 62443, into a practical roadmap. We will examine each of these dimensions in depth:

• Boundary Defence: Moving beyond simple perimeters to establish robust zones and conduits.
• Identity and Credentials: Why identity is the new air gap, requiring strict cryptographic verification and multi-factor authentication.
• Lateral Movement: Eliminating broad network access to ensure a compromised device does not create a bridge into the critical operational technology environment.
• System Hardening: Securing legacy devices and endpoints to prevent a single compromised machine from taking down the plant floor.
• Visibility and Detection: Gaining the crucial insight required to identify manipulation of control logic before an incident impacts your mean time to repair.

Because these dimensions are independent, an adversary who successfully bypasses a network boundary does not automatically acquire the authentication token needed to issue an operational command. We intend to cut through the marketing fluff and focus strictly on the structural realities of securing operational technology. Register today to learn how to fundamentally reduce your risk profile.
