more and more new challenges. Changes of the security environment and increase of threats can be felt throughout all the Euro-Atlantic area and Latvia is a part of this area. Some of these threats directly affect the national security of the Republic of Latvia. The Republic of Latvia is a member state of EU and NATO. Irrespective of financial support and investments provided by EU and safety guarantees of NATO, the Republic of Latvia has a number of priorities in the national security sector and these priorities must be dealt with independently – the most important of them being the internal security. Identification, prevention and overcoming of threats to the national security will be successful if the whole state administration is involved; if so, the society will understand these efforts and take part in the activities. The national security priorities for the prevention of security threats included in the Concept will be used while planing and defining specific measures and instruments for neutralisation and prevention of national security threats that will be included in the Nationals Security Plan.
