NIS2 Requirements in the OT
Cybersecurity & risk management become an integral part of OT operations
How to implement NIS2 in your OT
This eBook examines the impact that the updated European Network and Information Security Directive (NIS2) will have on organisations (or entities, as they are referred to in the Directive). The eBook starts with a brief categorisation of the NIS2 Directive within the larger framework of the European Cybersecurity Strategy. Chapter 2 discusses the practical limitations that many organisations will face when implementing the requirements in OT. In particular, it looks at the residual risk this creates. Chapter 3 explains how these limitations can be overcome and how the residual risk of the real ability to act can be brought under control. Finally, Andreas Könen from the BMI provides tips on the steps companies should take.
Challenges of NIS2 in the OT
The implementation of NIS2 poses some serious challenges for companies:
- How can the OT black box be opened up to enable asset management and intrusion detection in industrial infrastructure in the first place?
- How to deal with third-party OT components and systems that offer little to no security functions?
- How can the effectiveness of cyber security measures be verified?
One unknown component or insecure system in the OT is enough to jeopardize the overall security of the OT.
Get intrusion detection according to NIS2 and residual risk under control
The top priorities for companies when implementing NIS2 therefore include:
- Examine the OT for existing risks and embed it in risk management and IT security.
- Create visibility in OT in order to identify all assets and detect intrusions and potential disruptions to industrial processes at an early stage.
- Get the residual risk from the supply chain under control by identifying dangerous communication or activities of components and systems in the OT when they first occur.
- Build up internal OT security expertise.
