health, humanitarian, environmental security, etc. While admitting that security, at times, appears as a matter of perception(protection of the State, protection of citizens and their properties, freedom from threats against the society and its values), it does essentially concern a functional category of supervisory institutions and inter-connected operational departments(ministry in charge of security and security departments). In this regard, security represents a service function of the State whose duty is to protect institutions, citizens and their properties. Therefore, it must be viewed against the background of its military and non-military dimensions. In fact, security includes various functions, namely: defence, law enforcement, intelligence information, management of threats and subversive actions against the State and against peace. It also covers bilateral and multilateral arrangements. Moreover, as a polysemous subject, security has human and developmental dimension which is manifest through the human security and practical micro-disarmament concepts(« exchanging weapons for development» concept initiated by the United Nations during the'90s, in the bid to stop the proliferation of small arms and light weapons). Today, security assumes so much importance that it affects certain fundamental human right values such as freedom, democracy and development. 1.2. Safety. This term is often given the same meaning as security. Safety generally indicates all the required conditions to be out of danger. By extension, it is used to signify freedom from danger and protection against exactions, injustice, attacks and foreign infiltration. It is also the state of mind of a person who is conscious of his/her secured well-being. 1.3. Internal Security. Basically speaking, this term refers to the security of persons and properties, the State and its decentralised departments within a given geographical space. Internal security is articulated throughout the national, federal or regional territory by means of public law enforcement agencies 7
