Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, pursuant to the Answer of 11 October 2018 to Question 176669, how many cyber incidents affecting critical national infrastructure were reported in each of the last three years.

The National Cyber Security Centre has responded to a number of incidents impacting CNI companies and their supply chains since its creation including close working with companies on mitigation. Given the complexity, interdependency, and scale of the CNI and its supply chain it is not currently possible to provide the information requested. The government is committed to improving the quality of data available and making cybersecurity incidents easier to report.
