🏭 Cybersecurity Nightmares in Smart Manufacturing: Technology Patching and Siloed Teams 🚨

[Alper Aktaş]

Smart manufacturing has created a convergence between digital systems and physical processes. However, security programs have not always kept pace with this speed. This situation makes the industrial sector an attractive target for cyber attackers. This sector, once built on physical security and operational efficiency, is now the primary focus of nation-state actors. They know that the disruption of a single production line or facility can create ripple effects across industries, economies, and borders. Modern manufacturing environments are more connected than ever, but this connectivity also brings risks.

💡 Awareness Exists, But Where is the Solution?​

It's hard to find a manufacturing leader who isn't aware of the threat. The real challenge lies in how organizations will defend themselves and respond to attacks. While smart manufacturing brings together digital systems and physical processes, security programs struggle to keep up with this change. Engineering teams control operational decisions, while IT security takes on the responsibility of defending against cyber threats. This situation creates a gap in terms of ownership, language, and accountability.

🤝 Common Language, Shared Responsibility​

In our work with global manufacturers, we often hear two truths: Traditional remote access and privileged access approaches are now understood to be insufficient. However, there is no clear agreement on who owns the problem. Is it the security team, or the plant engineer? The answer is both. Until these teams come together to rethink how secure access is designed, managed, and implemented, vulnerabilities will persist.

⚙️ Technology Patchwork and Security Challenges​

Part of the problem stems from the fact that digital transformation in manufacturing is not always homogeneous. Some facilities implement the latest robotic technologies and cloud-connected analytics, while others continue to operate with systems installed 20 years ago. This technology and system patchwork makes it difficult to standardize security across sites, especially when third-party vendors, contractors, and Original Equipment Manufacturers (OEMs) are involved in ongoing maintenance and troubleshooting processes. Many of these users require privileged, often remote, access to critical systems without prior planning.

The default response has been to provide persistent access via Virtual Private Networks (VPNs) or shared credentials. This opens the door to lateral movement from compromised user endpoints, credential theft, and prolonged infiltrations.

🚨 Real-Life Scenarios and Risks​

This is not a theoretical concern. We have observed many cases where insecure remote access served as an entry point for attackers to penetrate deeper into manufacturing networks. Sometimes, the access methods were not even officially documented. They were simply passed from one engineer to another as "the way things have always been done," without audit or traceability. This is particularly risky in an environment where adversaries are patient, well-funded, and highly skilled.

It's time to stop treating secure access as an afterthought and start viewing it as a strategic control point for smart manufacturing.

🚀 Security and Engineering Teams Must Partner​

This means making informed decisions about who can access which systems, under what conditions, and with what level of visibility and approvals. It means implementing time-bound, task-specific permissions instead of broad, always-on connectivity. And it means choosing tools and architectures that support this level of granularity without slowing down operations or requiring major infrastructure overhauls.

To do this effectively, security and engineering teams need to partner more closely. This starts with a common language and shared incentives. For Chief Information Security Officers (CISOs), this means understanding the constraints and realities of industrial environments, including the need for simplicity, uptime, and operational autonomy. For engineers, it means recognizing that cyber risk is no longer an abstract concern. It has a direct impact on plant availability, equipment integrity, and even personnel safety.

🛡️ Future-Proof Security Models​

The most successful organizations are those that make security a shared responsibility. They adopt access models that do not rely on direct network connectivity between untrusted user devices and critical systems. Instead, they use methods that isolate protocols in manufacturing environments, monitor sessions in real-time, and record every action taken.

They are eliminating persistent credentials and replacing them with just-in-time authentication. And they are enabling secure collaboration between remote experts and on-site personnel without exposing core infrastructure.

This shift not only reduces risk but also improves control, enables better decision-making, and streamlines operations and compliance.

Regulatory frameworks like NERC CIP, IEC 62443, and TSA SD2 are increasingly demanding that organizations demonstrate their ability to manage and monitor remote access. The ability to show that only authorized users can perform only approved actions on only appropriate systems is rapidly becoming a fundamental expectation.

🎯 Simple Solutions, Big Impact​

The important thing is that these improvements do not require large IT projects or corporate "rip and replace" efforts. In fact, the most effective solutions we've seen are those that fit the existing state of manufacturing teams. They work with existing identity systems, support air-gapped or low-bandwidth environments, and can be deployed in hours instead of months.

Most importantly, they give organizations the ability to always see, control, and verify access to their critical systems.

As more manufacturers adopt smart technologies, the pressure will only increase. The shift to connected, autonomous, and Artificial Intelligence (AI)-driven operations offers incredible promise, but also opens up new avenues for cyberattacks. The industry cannot afford to ignore the "access layer." This is where security, safety, and productivity intersect.

Ultimately, the question every smart manufacturing leader must ask is: Are we building a future-proof security model that matches the pace of our operational innovation, or are we hoping that yesterday's access methods will protect tomorrow's manufacturing?

Security should not be an obstacle to progress. It should be the foundation that allows manufacturers to embrace the future with confidence. Getting there starts with one fundamental change: making secure access a core design principle, not an afterthought.
