Are there legal obligations in the EU for OT security readiness?

-

In the EU, is there a legal obligation to introduce OT security solutions and establish a response system for security monitoring and vulnerability management of OT systems such as PLCs and HMIs within the OT network environment?

The answer is Yes. There are legal regulations such as NIS2.





1. What is NIS2?

NIS2 Directive (Adopted in 2023, Member States Must Implement by October 2024)

  • Strengthens and expands the original NIS (2016) directive to improve cybersecurity across critical sectors, including OT environments.
  • Applies to both IT and OT systems to prevent and mitigate cybersecurity incidents.
  • Introduces stricter security obligations, expanded sector coverage, and heavier penalties.

2. Key OT Security Requirements Under NIS2

RequirementDescription
Asset Identification & MonitoringContinuous monitoring and inventory of OT assets, including PLCs, HMIs, and SCADA systems.
Vulnerability ManagementIdentifying, assessing, and mitigating vulnerabilities in OT systems.
Threat Detection & Incident ResponseReal-time security monitoring, anomaly detection, and response capabilities.
Secure Network ArchitectureImplementing segmentation, firewalls, and intrusion detection for OT networks.
Supply Chain SecurityEnsuring third-party OT systems comply with security standards.
Incident Reporting ObligationReporting cyber incidents within 24 hours to national authorities (e.g., ENISA, CSIRTs).

To comply with these requirements, organizations must adopt OT security solutions for monitoring, vulnerability management, and incident response.

3. Are Organizations Legally Required to Implement OT Security Solutions?

While NIS2 does not explicitly state "you must install OT security solutions," it mandates cyber risk management measures that practically require OT security tools.

  • Manual security management is insufficient for OT networks due to their complexity.
  • Compliance requires continuous monitoring, which can only be achieved through OT security solutions.
  • Incident reporting requires detection capabilities, which OT security solutions provide.

4. Who Must Comply? (NIS2 Targeted Organizations)

CategorySectors Covered
EssentialEnergy, Transport, Water, Health, Digital Infrastructure, Banking, Financial Market Infrastructures, Public Administration
Important Manufacturing (Chemicals, Electronics, Machinery, Aerospace), Postal Services, Waste Management, Food, Research

Any organization managing OT networks in these sectors is legally required to implement cybersecurity measures, including OT security monitoring and vulnerability management.

5. Penalties for Non-Compliance

Failure to comply with NIS2 leads to severe financial and operational penalties.

Entity TypeMaximum Fine
Essential EntitiesUp to €10M or 2% of global annual revenue
Important EntitiesUp to €7M or 1.4% of global annual revenue

Additionally, regulators can enforce operational bans, demand leadership changes, or suspend business operations for repeated violations.

6. Why OT Security Solutions Are Necessary for NIS2 Compliance

Network Traffic Monitoring (SPAN/TAP, Deep Packet Inspection for OT protocols)
Vulnerability Management (Scanning, Risk Assessment, Patching Strategy)
Intrusion Detection Systems (IDS) for OT (Detecting anomalies in OT traffic)
Asset Inventory & Visibility (Mapping all OT devices, firmware tracking)
Threat Intelligence & Incident Response (Automated alerts, forensic analysis)

Without these capabilities, NIS2 compliance would be nearly impossible, making OT security solutions a de facto legal requirement.

***In the case of the Netherlands, the NIS2 will come into effect in Q3 2025 and will force companies***

Final Conclusion: 

OT security compliance is not optional-organizations risk financial and operational penalties

Don't confuse DCS, PLC and SCADA in front of OT specialists

DCS, PLC and SCADA are not the same. If you keep talking only about PLC security in front of the Oil&Gas industry executives where DCS is the main focus, they will not recognize you as a proper expert. We need to understand the characteristics of OT systems such as DCS, PLC, and SCADA accurately, also respect each OT culture uniquely and finally approach the sites in the right way. Don't be confused, here’s a clear and accurate explanation of DCS, PLC, and SCADA . 1. Distributed Control System (DCS) Concept A DCS (Distributed Control System) is an automated control system used for large-scale industrial processes that require continuous operation and high reliability. It consists of multiple controllers distributed throughout the system, which communicate with each other to manage complex processes. Key Features Used in large-scale, continuous processes (e.g., oil refineries, power plants). Decentralized control architecture with multiple controllers working together. Pr...

A comprehensive list of 20 threat scenarios in OT security along with detailed descriptions and detection rules that can help identify and respond to these threats. This playbook-style table covers different types of attacks—from unauthorized access to insider abuse—with corresponding rules and indicators to alert security teams. # Threat Scenario Detailed Description Detection Rules & Indicators 1 Unauthorized Remote Access Attempt An attacker uses stolen or weak credentials to access OT networks remotely. - Log Analysis: Monitor VPN/RDP logs for unusual login times, geolocation mismatches, and failed/successful login bursts. - User Behavior Analytics (UBA): Alert on deviations from normal remote access patterns. - Anomaly Detection: Trigger an alert when a remote session is initiated from an unusual IP or geographic region. 2 Malware/Ransomware Infiltration in OT Network Malicious code is introduced into the OT network via compromised endpoints or phishing, potentially encr...

Let's create our own ICS Labs in the VMs: A Step-by-Step Guide Building an Industrial Control System (ICS) lab in a virtualized environment allows security researchers, engineers, and penetration testers to safely simulate industrial networks, study threats, and test security defenses. Below is a detailed step-by-step guide to creating an ICS lab , including HMI, EWS, PLC, and other critical components. 1. Lab Architecture Overview Key Components in an ICS Lab: HMI: Graphical interface for controlling industrial processes. Engineering Workstation (EWS): Used to configure PLCs and SCADA systems. PLC: Controls physical processes (e.g., motors, valves). SCADA System: Supervisory control and monitoring of ICS networks. Historian: Logs and stores process data for analysis. Networking Components: Virtualized switches, routers, and firewalls to segment ICS networks. Attacker Machine: Kali Linux or Metasploit for penetration testing. 2. Choosing the Virtualization ...
