Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, how many distributed denial of service cyber attacks on central Government Departments have occurred in each year since 2010.

One of the four principal objectives of the new National Cyber Security Centre (NCSC) is to respond to cyber security incidents to reduce the harm they cause to the UK. Since its formation, the NCSC has managed approximately 60 serious incidents affecting government and industry each month. The total number of cyber incidents affecting central government departments, including DDoS attacks and ransomware infections, is not centrally recorded.
