Design and Validation Framework for Multi-Level Cybersecurity and Privacy Protection in Modern Digital Infrastructures

Vollständiger Abstract

Worum geht es in dieser Arbeit?

The increasing complexity of cyber threats, interconnected technologies, and data-intensive digital services has exposed limitations in security strategies that depend on isolated controls. This study develops a multi-level cybersecurity and privacy framework that integrates complementary controls across physical, network, endpoint, application, data, identity and access management, monitoring and incident response, and human and policy domains. The framework was developed through structured synthesis of the ten cybersecurity and privacy studies reviewed in the source manuscript and alignment with established cybersecurity guidance. The revised model treats monitoring and incident response as a cross-cutting capability and privacy and governance as cross-cutting concerns. It further introduces a measurable evaluation structure based on layer-specific security indicators and an overall Multi-Level Cybersecurity Resilience Index. The framework is mapped to NIST Cybersecurity Framework 2.0, ISO/IEC 27001:2022, and Zero Trust principles. The resulting architecture provides a practical basis for coordinating preventive, detective, responsive, recovery, governance, and privacy controls. Because the source studies did not include primary empirical testing, the present manuscript does not claim empirical effectiveness; instead, it specifies a validation protocol using expert assessment and/or controlled simulation. This study contributes an integrated architectural model and a measurable evaluation approach for organizations seeking adaptive and resilient cybersecurity.
