National Cyber Security Centre

The National Cyber Security Centre​ (NCSC) was established in 2011 and is the operational unit of the Department in regard to network and information security. The role of the NCSC is to lead in the management of major cyber security incidents, provide guidance and advice to citizens and businesses, and manage cyber security related risks to key services.

In common with similar bodies in other EU Member States, the National Cyber Security Centre has also steadily moved towards a more proactive approach across a range of areas. The provisions of the EU Network and Information Security Directive (link to NIS webpages) have been used to develop a quasi-regulatory approach for critical infrastructure providers, an approach which operates in tandem with the existing and ongoing work of the NCSC.

The Computer Security Incident Response Team (CSIRT) which is part of the NCSC also has a series of specific responsibilities, as set out in Regulation 10 of SI No. 360 of 2018 (the Statutory Instrument used to sign the EU Network and Information Security Directive into Irish law). The Computer Security Incident Response Team is responsible for risk and incident handling in the State and its responsibilities include;

  • Monitoring incidents within the State
  • Providing early warnings, alerts, announcements and dissemination of information about risk and incidents to relevant stakeholders
  • Responding to incidents notified to it
  • Providing dynamic risk and incident analysis and situational awareness
