The article is devoted to the identification and their correlation of such legal concepts as “constitutional and legal status of a person” and “information security of a person”. The article is focused on the main factors affecting the constitutional and legal status of a person, which include political and economic conflicts, the crisis of international law, the widespread use of new technologies, including information and communication technologies. In order to identify the nature of the relationship between the constitutional and legal status and information security of a person, the author analyzes the content of the concept of “information security of a person”, “digital security of a person”, “cybersecurity of a person”. Under the information security of a person, which is much more comprehensive than digital security, the author understands the achievement of personal security along with the guarantees of realization of rights, freedoms and legitimate interests related to information. It argues that the information security is connected not only with ensuring the right to information, but also with a whole range of constitutional rights, in particular, with such ones: 1) the openness and reliability of information about the activities of all public authorities; 2) obtaining information that needs to exercise other constitutional rights (the right to access to cultural values, the right to health protection, etc.); 3) information related to a person's identity, personal data; rights realized in the digital space by information and communication technologies. The author studies the provisions of the National Security Strategy of the Russian Federation and the Information Security Doctrine of the Russian Federation, which has showed that the rightful content of the information security of a person is to protect human rights and freedoms and relevant legitimate interests. The article concludes that personal information security cannot be recognized as a new human right. It is an element of the constitutional and legal status and refers to the guarantees of human rights and freedoms.<strong >
