How Novimeq Automation can ensure your OT network is secure, resilient, and ready for the future.

In today’s fast-paced industrial world, Operational Technology (OT) networks quietly keep everything running—whether it’s factory lines, power grids, or water treatment plants. They are the unsung heroes of manufacturing and infrastructure, ensuring that physical processes happen reliably, safely, and without a hitch.

But here’s the thing: as we connect OT systems with IT networks to drive efficiency and gather data, these systems become more vulnerable than ever before. Think about this—what used to be isolated machinery is now part of a digital ecosystem. While this convergence is powerful, it also opens the door for cybersecurity risks that can wreak havoc on production, safety, and revenue.

The recent years have proven one harsh truth: cyber threats don’t just target emails and servers—they can target your production floor. And when they do, the cost of recovery is often far greater than the cost of prevention.

What is OT, and Why Does IT-OT Convergence Matter?

Let’s break it down.

Operational Technology (OT): This refers to the systems that control and monitor industrial operations—like factory robots, conveyor belts, PLCs (Programmable Logic Controllers), and HMIs (Human Machine Interfaces). These systems prioritise stability and safety over speed or updates. If a robot arm or power grid goes offline, the risks can be immediate and severe.

IT-OT Convergence: Modern businesses now integrate IT (data systems) with OT to improve operations. Real-time monitoring, predictive maintenance, and automation are game changers. But as OT systems connect to IT networks, they inherit the vulnerabilities of the digital world. Suddenly, a cyber threat can jump from an email server to a PLC running your factory.

Consider this: In 2015, a European power grid was targeted by hackers who remotely manipulated circuit breakers, cutting off power to hundreds of thousands of homes. Similarly, in 2017, the ransomware attack on aglobal logistic company disrupted their global logistics network, causing $300 million in losses.

These aren’t just headlines—they’re cautionary tales for any business running critical operations.

The Hidden Risks in OT Networks

Most OT networks weren’t built with cybersecurity in mind. Factories evolve over decades—new machinery is added, old systems are patched up, and sometimes, nobody really knows what’s still connected. Sound familiar?

Here are some common vulnerabilities lurking in OT systems:

1. Legacy Devices: Machines installed 30-40 years ago often don’t support modern security updates. Recovering from a failure can be nearly impossible because documentation is outdated—or non-existent.

2. Unmanaged Network Components: Unsecured switches and open ports are low-hanging fruit for attackers.

3. Poor Backup Practices: A ransomware attack or hardware failure could halt production for days if you don’t have reliable backups.

4. Physical Security Gaps: Who can access your control panels, servers, or factory floors? Sometimes, all it takes is an unlocked door.

5. Misconfigured Networks: Weak firewalls allow threats to move across systems, causing widespread damage.

It’s easy to overlook these risks when “everything seems fine.” But downtime caused by a cyberattack or equipment failure can cost millions in lost production.

Why OT Network Assessments Are Essential

Here’s the good news: most vulnerabilities can be identified and addressed before they become problems. An OT network assessment is like a health check for your industrial systems—it uncovers weaknesses, prioritises solutions, and strengthens your entire operation.

Here’s what happens during an OT network assessment:

1. Asset Identification and Documentation: Systems, cables and devicesare documented, including outdated hardware or unsupported software versions. Think of this as creating a roadmap of your network so you know exactly what needs attention.

2. Vulnerability Detection: Weak points—like open ports or unmanaged switches—are flagged so they can be addressed before they become entry points for attackers.

3. Network Topology Analysis: Your network architecture is reviewed to ensure it’s optimised for both performance and security. Segmentation (isolating critical systems) helps prevent threats from spreading.

4. Physical Infrastructure Inspection: The plant layout is inspected for physical vulnerabilities—damaged cables, unsecured connectors, or inconsistent naming conventions that can lead to confusion during incidents.

5. Backup and Recovery Evaluation: How resilient is your system in case of a failure? Assessments evaluate recovery methods, backup testing, and retention policies to ensure minimal downtime.

6. Policy and Personnel Review: Security isn’t just about systems—it’s also about people. Policies for visitor access, device usage, and team training are reviewed to align with cybersecurity best practices.

7. Physical Security Assessment: Unsecured control panels or server rooms are a big risk. Assessments ensure physical access is as tightly controlled as digital access.

The Cost of Waiting Too Long

Many industries hesitate to invest in OT cybersecurity until something goes wrong. But waiting for a cyberattack—or a hardware failure—can be incredibly costly. For example:

• Financial Losses: Production halts for hours or days, impacting revenue and customer commitments.

• Safety Risks: Malfunctioning systems can pose direct threats to workers and the environment.

• Long Recovery Times: Without proper backups, recovery can take much longer than expected.

Simply put, downtime is expensiveand sometimes dangerous but preventable.
