Cybersecurity Compliance with NIS2
In today’s fast-evolving digital landscape, cybersecurity is paramount. Ensuring Cybersecurity Compliance with NIS2 is more important than ever, as NIS2 represents a significant upgrade to the existing EU Network and Information Security Directive (NIS1). This directive is crucial not just for IT but also for the Operational Technology (OT) sector, which is increasingly targeted by cyber threats. Let’s dive into what NIS2 is, why it matters, and how it impacts companies across various sectors, with a particular focus on OT.
Overview of NIS2
NIS2 is a revised version of the current EU Network and Information Security Directive (NIS1). Ensuring Cybersecurity Compliance with NIS2 sets out criteria for identifying operators of critical infrastructures and establishes minimum standards for their information security.
Applicability
NIS2 targets companies in specific sectors with more than 50 employees and an annual turnover exceeding EUR 10 million. These companies must adhere to stringent information security standards to safeguard their operations and data.
NIS2 Objectives and Requirements
Goals: NIS2 aims to elevate cybersecurity standards across the EU. It mandates effective cybersecurity measures for companies in 18 sectors, focusing on critical infrastructures. The goal is to ensure continuous and secure supply and market functionality amid rising cyber threats and complex supply chains.
Core Focus: Risk Management: Affected companies are required to conduct regular risk analyses and implement corresponding security measures. They must also ensure operational continuity or quick recovery in case of disruptions.
Mandatory OT Risk Management Measures: NIS2 mandates several technical and organizational measures based on the latest standards, including:
Network Segmentation
Secure Configuration
Identity and Access Management
Software Updates
Multi-Factor Authentication
Backup & Recovery
Crisis Management Measures
The directive incorporates Zero-Trust principles, emphasizing internal network security to prevent the spread of disruptions. Key components include access controls, monitoring, authentication, and encryption.
Implementation Timeline
EU member states have until October 17, 2024, to incorporate NIS2 into national law. While the specific details of the NIS2 implementation law (NIS2UmsuCG) are still being finalized, companies are advised to start preparing now to meet the requirements.
Preparatory Steps
Establishing Prerequisites: To comply with NIS2, companies must gather current information on their operational technology (OT) assets and their statuses. This step is crucial for the initial assessment and planning phase to identify critical assets.
OT Asset Management: Building an OT-Asset Management system is the first step towards compliance. This system provides transparency and supports the implementation of NIS2 requirements.
Benefits of OT-Asset Management:
Efficient Management: Manages OT assets throughout their lifecycle with appropriate tools, processes, and organization.
Asset Inventory: Lists all OT assets like PLC’s or robot’s with relevant data (e.g., configuration, firmware, OS version, patch status, and location).
OT-Asset Management for NIS2:
Risk Analysis: Provides necessary data to assess risks, determine protection needs, and design measures.
Network Segmentation: Helps group and protect OT assets within secure network segments.
Secure Configuration: Tracks and updates the configuration status of each asset.
Access Management: Clarifies who can access specific assets and their locations.
Obsolescence Management: Obsolescence management is critical in OT to ensure that equipment and systems remain functional and secure throughout their lifecycle. Proactively managing obsolescence helps avoid unexpected failures and vulnerabilities that could compromise operations. It includes monitoring the lifecycle of assets, maintaining inventories, and forecasting potential disruptions [NUMBER].
Vulnerability Detection: Regular vulnerability detection in OT systems is essential to identify and address security weaknesses before they can be exploited. This process helps safeguard critical infrastructures from cyber threats by pinpointing potential entry points and mitigating risks [NUMBER].
Backup for Disaster Recovery: A robust backup and disaster recovery plan ensures that OT systems can quickly recover from disruptions caused by cyberattacks, equipment failures, or natural disasters. Implementing comprehensive backup solutions and recovery protocols is vital for maintaining operational continuity [NUMBER].
Versioning and Documentation of Changes in Software Programs: Keeping detailed records of software versions and changes is crucial in OT environments. This practice helps track updates, manage configurations, and quickly identify the root causes of issues. Proper documentation supports compliance with NIS2 and enhances overall system reliability [NUMBER].
Importance Beyond Security
A professional OT operation supports not only security projects but also facilitates technological advancements and production optimizations. Transparency and well-defined processes are essential for various digitalization projects, such as energy data management.
Starting NIS2 Implementation
Implementing NIS2 requirements involves defining OT assets, gathering relevant information, and establishing processes. Companies should begin building an OT-Asset Management system now to ensure a smooth transition and compliance with NIS2.
Conclusion
Clarity and transparency regarding assets are crucial for a swift start and sustainable OT security measures. An OT-Asset Management system provides the necessary information for NIS2 implementation, extending benefits beyond mere security considerations. By understanding and preparing for NIS2, companies can not only comply with regulations but also enhance their overall cybersecurity posture, ensuring a resilient and secure operational environment.
