The NIS2 Directive introduces new obligations for companies responsible for vital infrastructures, such as those in the energy, water, and transport sectors. A key component of these regulations is conducting a thorough risk analysis focused on the security of network and information systems. This article provides practical guidance for conducting a risk analysis that complies with the NIS2 requirements.

Steps for a successful risk analysis

1. Identification of critical assets

The first step is to identify all critical systems and processes that are essential for the continuity of the infrastructure. This includes both IT and OT systems. By gaining a clear picture of these assets, it can be better determined which components require extra attention.

2. Threat Assessment

Analyzing relevant threats and vulnerabilities is essential. These can range from cyberattacks to physical sabotage. It is important to include both internal and external threats in this analysis. This step helps to prioritize risks and determine measures.

3. Implementation of security measures

Based on the results of the risk analysis, appropriate security measures must be implemented. Consider measures such as network segmentation, advanced monitoring tools, or improving access control. Each measure should be aimed at minimizing risks and protecting critical systems.

NIS2 Compliance

NIS2 requires not only identifying risks and implementing security measures but also imposes reporting obligations. Companies must report security incidents to the relevant authorities, such as the national CSIRT, in a timely manner. This obligation emphasizes the importance of monitoring and continuous evaluation of the security status.

An accurate and detailed risk analysis is essential for companies that manage vital infrastructures. By taking the right measures and complying with the NIS2 requirements, companies can better deal with security threats and ensure the continuity of their services. Identifying critical assets and evaluating risks forms the basis for a robust security strategy.
