Cybersecurity that keeps operations running

Integrating IT and OT security

Operational technology (OT) is at high risk to be hit by a cyber attack due to legacy systems, Industry 4.0, the Industrial Internet of Things and increasingly connected production systems and machine tools. If the crucial OT environment is compromised, production is shut down, which can have a devastating impact on business continuity and can result in loss of revenue.

Manufacturers admit to running on outdated or not secured IT systems and that they always make cybersecurity improvements after an incident. This shosw that protecting factory environments – from traditional devices to state-of-the-art infrastructures – is crucial. 

Key cybersecurity challenges for manufacturing

Securing both IT and OT expand_more

Securing both IT and OT

In the manufacturing sector, IT is actively used in OT/ICS (industrial control system) environments and due to an increasing number of connected IT and OT devices, the attack surface is rapidly expanding. This creates an increasingly complex environment that often leaves companies exposed. Cybercriminals attacking OT can cause significant damage, for example shutdowns, equipment damage, and the loss of financial assets, reputation, and intellectual property.

Manufacturers should implement security that combines technology optimized for IT as well as OT, so they can centrally manage cyber defense without interrupting operations. At Trend Micro, we have expertise in both areas. We connect OT Security solutions (TX-One) to Vision One to create a single security platform for IT and OT.

Finding a patch window expand_more

Finding a patch window

Since manufacturers are 24/7 organizations, OT has to be available at all times. Thus, finding a patch window is a challenge, which sometimes means security patches are not applied and field engineering teams keep using outdated OT. This makes OT systems vulnerable to cyber-attacks.

When patching, you risk that applications may temporarily not run properly due to a software conflict after patching. Because of the risk of downtime, the facility provider or vendor does not always allow asset owners to install security patches. And with certain manufacturing devices, the product makers can prohibit software patches by anyone but themselves to preserve device integrity. Manufacturers need a contextualized, risk-based approach and good overall attack surface risk management.

Legacy systems expand_more

Legacy systems

Manufacturers often work with older legacy systems because equipment is used for a long period of time. However, developments have gone so fast in recent years, making legacy systems no longer adequate for the job. In addition, these systems are more difficult to secure due to their age and the fact that every system needs a different security approach.

Trend Micro offers various solutions based on virtual patching to secure legacy systems, both host based and network based. 

Supply chain risks expand_more

Supply chain risks

Manufacturing companies typically have complex global supply chains, relying on many third-party vendors and suppliers for parts, components, and software. It is crucial to ensure all parties have adequate cybersecurity measures in place. If this is not the case, attackers may try to exploit vulnerabilities to gain access to the manufacturer's network via supply chain attacks, affecting many organizations through one single vendor.

To minimize the cybersecurity risk in your supply chain, it is essential to gain a comprehensive understanding of the supply chain itself and corresponding data flow, and to identify high-risk suppliers. 

More sensors leads to more data expand_more

More sensors leads to more data

Sensor data can make the production process more efficient, therefore data collection, data sharing, and data analysis are becoming increasingly important. However, this also makes the manufacturer more attractive for attackers. Another difficulty is that an environment includes assets from a wide range of manufacturers and data from these assets are not always compatible.

A comprehensive security approach is crucial. By using an OT zero trust approach, you can inspect assets as they arrive and segment the network with hardware to secure the data flow (data in use, data in transmission, and data at rest). 

Flat network expand_more

Flat network

Your factory uses many devices. Cyber attackers only need to infect one device to gain access to the entire network, risking massive loss. Network segmentation provides a solution. However, to deploy network segmentation, configuration settings in existing networks need to be changed, which could have an impact on system availability. Furthermore, it is a time-consuming task. Ensure you avoid the spread of a cyber incident by deploying network segmentation.

Get ready for NIS2

Specifically for the manufacturing sector, it is important to pay attention to the efforts of chain partners in terms of cybersecurity. An updated version of the NIS2 directive will be implemented starting in 2025. This will have a huge impact on the manufacturing sector, as the security regulations will touch all critical services. Manufacturers will also be expected to monitor the security measures of their chain partners. To ensure compliance, your organization will need a variety of measures such as detection & response, awareness training and remediation plans.
