B3S Water/Wastewater
B3S Water/Wastewater – Security for Your Critical Infrastructure
Protect your systems against cyberattacks and comply with the requirements of the BSI Act – we support you in the implementation.
Key Information
The sector-specific security standard (B3S) for the water and wastewater sector specifies the requirements of the
BSI Act and the BSI Critical Infrastructure Ordinance (BSI-KritisV) for operators of critical infrastructures.
Utility companies that reach or exceed the legal thresholds are obliged to secure their IT systems, processes, and components accordingly.
Proof of implementation must be provided to the Federal Office for Information Security (BSI) at least every two years.
The B3S defines minimum IT security requirements specifically tailored to the water/wastewater sector. The goal is to ensure supply security even under growing cyber threats.
In practice, this means that companies must protect their IT infrastructure in such a way that outages or manipulations caused by attacks are prevented.
This includes organizational measures (e.g., clear roles and responsibilities), technical safeguards (e.g., firewalls, attack detection systems, emergency management), as well as continuous improvement of security processes.
This ensures that critical tasks such as the provision of drinking water or wastewater disposal can always be carried out reliably.
