Cyber Security

The term 'Cyber Security' refers to the body of technologies, processes, and practices designed to protect networks, devices, programmes, and data from attack, damage, or unauthorised access. As such, it refers to the full range of measures designed to protect IT systems and ensure the confidentiality, integrity, and availability of data services.

Disruption to our digital assets brings significant economic costs and undermines trust and confidence in them. The State works to reduce risks to Internet infrastructure and services in the interests of a resilient, secure and trustworthy online environment that citizens and businesses can rely upon for social and economic interaction. We work with other Government Departments and Agencies, and a range of critical infrastructure operators and international partners to protect the security of key systems and data.

We achieve this through the work of the National Cyber Security Centre (NCSC) and the development of legislative and non-legislative means. For more information on the Department's work in this area, please follow the links below.​
