Abstract

Cyberattacks increasingly threaten enterprise networks, creating significant risks to sensitive data and business operations. The purpose of this qualitative pragmatic inquiry was to explore the strategies Information Technology (IT) managers use to secure organizational networks from cyberattacks. Participants consisted of seven experienced IT managers with a minimum of 5 years of network security management experience, purposefully selected through LinkedIn. The study was grounded in integrated systems theory, which emphasizes the interdependence of technology, processes, and risk management within organizations. Data were collected through semistructured interviews and document analysis to examine practical approaches to securing networks. Thematic analysis identified eight core strategies: conducting regular risk assessments and mitigation, enforcing governance and compliance standards, building layered security architectures, strengthening user training and awareness, leveraging threat intelligence for adaptive defense, developing proactive incident response capabilities, securing operational technology environments, and aligning practices with government standards and Zero Trust principles. Based on these findings, the study recommends that organizations implement a comprehensive cybersecurity framework that integrates these strategies to reduce the likelihood of successful cyberattacks and enhance overall enterprise resilience. The implications for positive social change include the potential for IT managers and business leaders to implement integrated cybersecurity strategies that reduce data breaches, strengthen digital trust, and promote safer organizational and community environments.
