Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, how many cyber incident reports the National Cyber Security Centre received in last 12 months; how many of those reports resulted in being classified as significant; and how many of those reports were assessed as being sufficiently serious to require a cross-Government response process.

Over the past twelve months, the NCSC received in excess of one thousand reports of potential incidents. These reports were triaged and prioritised using our new categorisation process, working closely with law enforcement where required. As was recently noted in the NCSC’s Annual Review, between 1 September 2017 and 31 August 2018, 557 of these incidents warranted an enhanced level of investigation. A smaller subset necessitated a cross-government coordinated response. For operational reasons we cannot provide a more detailed breakdown of the figures.
