The National Security Systems Directorate:
- ensures that the system architecture performs as intended
- implements the decisions of the Officials' Committee for Domestic and External Security Coordination (ODESC) system
- builds specific capabilities and activates the system when necessary
- ensures that experience is retained as knowledge within the system.
A key role for the Directorate is to be the secretariat for the two governance boards (the Security and Intelligence Board and the Hazard Risk Board).
The Directorate is constantly alert to current events that may require a national security response. In times of crisis, the National Security Systems Directorate provides support to the Prime Minister and Chairs of ODESC and Watch Groups to enable them to take well-informed and timely decisions.
The Directorate also ensures that the right agencies are represented at meetings, understand their roles and responsibilities, and follow through on action points.
Outside times of crisis the team coordinates risk assessments, exercises and system testing, and contingency plans across government agencies, local authorities, and other related entities.
The Director of the National Security Systems Directorate is Catriona Robinson.
