An organizational and technological mechanism for the secure integration of the digital ruble’s trust infrastructure into the ecosystem of a credit and financial institution

The introduction of the digital ruble poses challenges for credit and financial institutions (CFIs) driven by the need to integrate external trust infrastructure into internal automated banking systems (ABS). The problem lies in the absence of standardized solutions regulating the secure interconnection of two heterogeneous security domains. The novelty of this work consists in the development of a holistic approach synthesizing technological protection measures and organizational procedures into a unified mechanism implemented on the CFI side. The objective of the article is to develop this mechanism, ensuring the minimization of risks of unauthorized access, information leakage, and disruption of business process continuity. The methodological framework is based on a systematic analysis of architectural solutions, a synthesis of threat modeling methods, and a risk-oriented approach. As a result, a two-circuit protection mechanism is substantiated, comprising a technological core (hardware cryptography, unidirectional gateway) and an organizational framework (zero-trust policy, in-line compliance). It has been proven that the proposed mechanism reduces the aggregate criticality of attack vectors at the integration stage by 35–40% according to the CVSS scale and forms the basis for a replicable standard solution.
