The National Cyber Security Centre (NCSC) has a broad remit across the cyber security of Government ICT and critical national infrastructure. The NCSC has three main roles: national incident response; information sharing; and Building Resilience. The NCSC supports Government Departments and other public bodies to improve the resilience and security of their IT systems to better protect services that our people rely upon, and their data.
The NCSC provides general guidance and notifications of major incidents and vulnerabilities on an ongoing basis to all Departments and agencies. However, it should be noted that the responsibility for the integrity and security of individual ICT networks lies with each individual Department or agency. Accordingly, decisions in relation to monitoring of networks are a matter of each entity to consider independently based on individual requirements and resources available.
