What are EOL/EOS devices?

EOL (End of Life) means product sales have ended, and EOS (End of Support) means technical support has ended. These devices no longer receive security updates and are vulnerable to attacks.

Why is OT security challenging?

Network changes are risky in OT environments to avoid disrupting production, making standard IT security measures difficult to apply. Balancing stability and security is key.

What will I learn in this seminar?

You'll learn new defense methods that don't require network changes, low-burden operational practices, and real-world implementation case studies.

Expansion of Ransomware Damage: EOL/EOS Devices as Weak Points in Manufacturing Sites

In recent years, ransomware attacks targeting the manufacturing industry have been increasing, with numerous cases severely impacting business continuity through production halts and shipment delays. In particular, devices that have reached EOL (End of Life) or EOS (End of Support) are unable to receive updates or security patches, making them potential entry points for ransomware attacks and factors in the spread of damage. As a result, many companies are working to strengthen OT security. However, fully supporting diverse OT/IoT protocols remains challenging, and in production environments lacking security specialists, the operational burden related to design, implementation, and maintenance continues to grow.

Why Is It Difficult to Control OT/IoT Devices and Defend Against Malware and Ransomware?

Controlling the wide variety of OT/IoT protocols is inherently difficult. Conventional IPS products, including existing solutions like TX One, are structurally insufficient for defending against zero-day attacks. Additionally, update processes are highly complex and cumbersome. In OT environments, minimizing impact on production equipment and control systems is the top priority. Therefore, unlike typical IT security measures, major changes to network architecture are difficult to implement, making the deployment of security measures itself a significant challenge. A solution that balances enhanced security with stable operations is urgently needed.

A New OT Defense Solution: Add Devices Without Stopping Factory Operations

This seminar will explain a new security approach that requires no major changes to existing OT network configurations—only the addition of new devices. We will present practical methods and implementation tips for strengthening preparedness against cyber threats such as ransomware, while minimizing operational burden on-site, supported by real-world case studies.
