Impact of Cybersecurity Capability, 5G Network Performance Optimization, and IT Service Management Maturity on Digital Service Reliability in U.S. Private 5G Network Operations

Abstract

Purpose— This study examines the influence of cybersecurity capability, 5G network performance optimization, and IT service management (ITSM) maturity on digital service reliability within the context of private 5G network operations in the United States. As organizations increasingly depend on private 5G infrastructures to support mission-critical digital services, ensuring high levels of reliability has become a strategic imperative.

Study Design/methodology/approach— The study develops a conceptual framework grounded in operational practices relevant to private 5G deployment, including threat monitoring, incident response, real-time performance analytics, service-level agreement (SLA) and operational-level agreement (OLA) enforcement, cloud–network integration, and automation.

Findings— Conceptual findings indicate that cybersecurity capability, 5G network performance optimization, and ITSM maturity each exert a positive influence on digital service reliability. Moreover, their combined and reinforcing interaction produces the strongest reliability outcomes, demonstrating that digital service reliability in private 5G environments is not the result of isolated technical strength, but of integrated organizational and technological capabilities.

Research Practical Implications The proposed framework offers practical guidance for organizations operating private 5G networks in the United States by emphasizing the need to align security engineering, performance optimization, and service management governance. The findings highlight how integrated deployment of cybersecurity controls, intelligent network optimization, and mature ITSM practices can significantly enhance service continuity, reduce operational disruptions, and strengthen resilience in mission-critical digital environments.

Originality/value— This study contributes original value by presenting an integrated, multidimensional framework that jointly examines cybersecurity capability, 5G performance optimization, and ITSM maturity within enterprise-managed private 5G networks—an area that remains underexplored in existing literature.
