The National Security Authority (NSM) (Norwegian: Nasjonal sikkerhetsmyndighet) is a Norwegian security agency (Direktorat) established on 1 January 2003 as the successor to Forsvarets sikkerhetsstab (FO/S). It is responsible for preventive national security, ICT security matters, including the national computer emergency response team (NorCERT), identifying national objects of special interest and reducing their vulnerability to internal and external threats. The agency performs threat analysis at the national level, and is also known to work with experts on computer security and with data encryption. The cooperation with the Police Security Agency (PST) and the Norwegian Intelligence Service (NIS) has been identified as a very important part of the task of maintaining an overview of potential threats to objects, and instituting proactive activities.
NSM also cooperates with the Directorate for Civil Protection and Emergency Planning (DSB), to prevent loss of life and maintain health, environment, important society functions, and material assets in connection with accidents, catastrophes, terrorism and other unwanted events in peace, crisis and war.
NSM is administratively governed and funded by the Ministry of Defence, but also reports to the Ministry of Justice and the Police in civilian matters.
