The National Security System is activated if the impact of a situation of national security is sufficiently complex, significant or imminent that the attention of the broader system is deemed necessary to tackle it.
The system is activated by DPMC on the instruction of (in priority order):
- the Chief Executive of DPMC;
- the Deputy Chief Executive Security and Intelligence, DPMC or;
- the Director of National Security Systems, DPMC.
Any activation of the system will usually be at the request of, or in discussion with, the Chief Executive of the lead agency.
