Minister: lock computers are not connected to the internet and hack requires burglary

Minister Cora van Nieuwenhuizen of Infrastructure and Water Management says that computer systems of locks have no connection to the internet. As a result, a hack requires a physical break-in. CDA MP Harry van der Molen asked questions about the security of the systems.

According to the minister, the critical water infrastructure is well secured. She will, however, consult with provinces, municipalities and water boards about how to improve the security of the systems used. Van Nieuwenhuizen claims that the risk is limited because the systems do not have an internet connection, ANP reports.

CDA MP Van der Molen asked questions in the House of Representatives on Tuesday afternoon in response to an article in Binnenlands Bestuur. This showed that locks and pumping stations are vulnerable to attacks. The software for controlling lock gates, for example, lasts 25 to 30 years, but is generally not supported for more than five years with security updates.

According to the magazine, water boards pay insufficient attention to the internet security of pumping stations and locks. If hackers can take over lock systems remotely, there is a risk that they will open the lock gates and cause the water level to rise. This can lead to, for example, floods.
