Abstract
The article examines the challenges of ensuring the cybersecurity of state infrastructure amid increasing digital risks and the growing sophistication of cyber threats. Purpose: The study aims to develop an integrated cybersecurity architecture based on international standards — ISO/IEC 27001, NIST SP 800-53, FAIR, CMMI, and MITRE ATT&CK — adapted to the national context of Kazakhstan. Methodology: The research employs a systemic and comparative analysis of existing cybersecurity assessment models, threat modeling in ICS/SCADA environments, and an examination of relevant regulatory frameworks and guidelines. Originality/Value: The originality of the study lies in the development of a conceptual cybersecurity architecture that integrates technological, organizational, and analytical components. The proposed model facilitates a shift from fragmented protective measures to a holistic risk management system, thereby enhancing the cyber resilience of state infrastructure. Findings: The findings demonstrate that integrating international frameworks significantly improves the cybersecurity and resilience of governmental systems and contributes to establishing an effective model for incident monitoring and response.
