In this article, we have attempted to generalise the current theory of judicial security. We emphasised that traditionally the judicial security theory includes a set of scientific views on the security of the court, judge, justice system and participants in the trial, and the status of the Judicial Protection Service. We briefly described the history of judicial security and drew attention to the reforms of recent years. An analysis of international judicial standards has shown that the security of the judiciary correlates to its independence. We proposed an interdisciplinary adaptation of the judicial security methodology, considering the limitations of specialised research on the subject. As a result, we concluded that the lack of a sole methodological guideline produces uncorrelated changes in the judicial security system elements. To systematise the theory of security of the judiciary, we propose to consider the methodological basis of international standards of justice.
