Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what his Department’s strategy is for tackling zero day exploits.

The Ministry of Defence (MOD) takes cyber security and resilience very seriously and is increasing our already substantial investment in this area as a result of the Integrated Review settlement. The MOD conducts a range of activities to ensure its systems are protected against attack. This includes working closely with industry and partners across Government, especially the National Cyber Security Centre. Although the unknown scope and quality of zero-day exploits means that their prevention can never be guaranteed, the MOD takes a proactive approach to identifying and managing threats and vulnerabilities. For security reasons we do not comment on details, as to do so could be useful to potential adversaries.
