The Zero Trust concept as a component of the data security architecture of the institution of the presidency under wartime conditions

Section: The library in the paradigm of information systems and technologies development

Abstract: This article examines the Zero Trust concept as a key element of the cybersecurity architecture of the institution of the presidency in wartime conditions. The relevance of the topic is driven by the rapid increase in cyberattacks targeting Ukraine’s critical state infrastructure since the beginning of the full-scale invasion by the Russian Federation, which has threatened the functioning of the highest bodies of state power and the continuity of presidential authority. The article outlines the essence and core principles of the Zero Trust model, which replaces the traditional perimeter-based security approach with continuous verification of every user, device, and network connection, regardless of location. The architectural components of the model - network microsegmentation, multi-factor authentication, the principle of least privilege, and continuous monitoring - are analyzed in the context of the specific security requirements of information systems supporting presidential institutions. The study also explores international experience in implementing Zero Trust within public administration systems, particularly in the United States, where the relevant strategy is formalized at the level of executive directives. A comparative analysis is conducted with cybersecurity approaches used in presidential institutions across NATO countries, identifying common organizational and technical solutions that could be adapted to the Ukrainian context. The authors argue that implementing a Zero Trust architecture for the institution of the presidency is not only a technical measure but also a strategic decision that directly affects the resilience of public governance in crisis conditions. Practical recommendations are provided for the phased implementation of the model, taking into account wartime constraints, existing infrastructure, and the human factor as a key vulnerability in any cybersecurity system.
