Searching for a possible concept of national security in the Republic of Serbia proceeds from the term 'security', with a view of the existing, but also some new forms of jeopardy, which have not so far been recognized as such, or they have not been paid enough attention to, all the way to including the social area into the state security. Basic international conventions, systemic laws and strategies which regulate these issues are indicated. Institutionally, additional attention is paid to military intelligence and security agencies in the country, without special analysis of already known details of these regulations, but providing the criticism of what would absolutely have to change with an aim to protect values and goods of already recognized individual and collective human rights and freedoms, as well as possible institutional change through the establishment of an agency within the Ministry of Defense. More adequate forms of work are suggested when it comes to specific challenges and threats and risks. Even though there is no parliamentary control of security services in all countries, it is indirectly concluded that it would be an optimal solution for our country. There is an example of Italian legislation, within which, for decades, there is a unified system of security, with tendencies to make changes which follow social development and status. The creation of a reformed system of national security in Serbia is insisted upon, from which new solutions would follow, as a part of the security system.
