A review of recent publications revealed limitations of current open publication systems in access control, data and metadata protection, and integration with external services. Threats were clarified and attack vectors classified to systematize risks originating from both internal and external environments, including unauthorized user actions, content modification, breaches in the review process, and infrastructure vulnerabilities. An integrated security model for the communication subsystems of the publication platform was developed to enhance security mechanisms, including the combination of RBAC and ABAC models for differentiated access control, the use of multi-level encryption and key management systems, UEBA algorithms for anomaly detection, and authentication protocols to ensure data integrity.
