Keywords: Social protection, national social security system, types of social security, aid, law The main task of any legal and democratic country is to guarantee, ensure, and protect fundamental human and civil rights and freedoms. To ensure and exercise the rights prescribed in the legislation of Ukraine, numerous institutions are being created, the functioning of which allows puting a person at the centre of social, public, and political life, thereby helping them to exercise their rights in due course (Kirilenko and Tolubyaka, 2016). One of the areas that is developing and requires constant improvement is the social sphere, namely social security, since it provides support for the most active working-age part of society. In other words, social security creates intangible and tangible goods designed to meet the needs and interests of people (Bezzub, 2019).
