The Food Sector is one of the UK's 14 Critical National Infrastructure sectors. Defra works closely with industry, the Cabinet Office and other Lead Government Departments (LGD) to monitor risks and ensure preparedness for, and response to, issues with the potential to cause disruption to food supply chains. Defra assesses the potential impacts of cyber and physical risks to the food supply chain as detailed in the National Security Risk Assessment (NRSA) and reflected in the National Risk Register (NRR). Defra works with Cabinet Office, as leads for the NRR, and Department for Science, Innovation and Technology, as the LGD for cybersecurity along with other Government Departments to ensure the range of potential impacts on the food system from these types of risks are considered in the dynamic risk assessment process.
