Cybersecurity in telecommunications: Defending networks against emerging threats

Ogunjinmi, Oluwabukunmi Folarin (2025) Cybersecurity in telecommunications: Defending networks against emerging threats. World Journal of Advanced Engineering Technology and Sciences, 14 (3). pp. 410-424. ISSN 2582-8266

The telecommunications sector, a cornerstone of global communication and critical infrastructure, faces escalating cybersecurity challenges as digital transformation accelerates. The proliferation of advanced technologies such as 5G, IoT, and cloud computing has introduced unprecedented vulnerabilities, making telecommunications networks prime targets for sophisticated cyber-attacks. This study examines the evolving landscape of cybersecurity in telecommunications, focusing on emerging threats and the efficacy of current defense mechanisms. Employing a mixed-methods approach, the research integrates a comprehensive literature review, case studies, and empirical data analysis to provide a holistic understanding of the challenges and solutions in this domain. The study identifies key threats, including Advanced Persistent Threats (APTs), ransomware, IoT vulnerabilities, and 5G security challenges, while evaluating the effectiveness of existing defense strategies such as firewalls, intrusion detection systems, and encryption. Findings reveal that while significant progress has been made in cybersecurity technologies, the dynamic and evolving nature of threats necessitates continuous innovation and collaboration among stakeholders. Case studies, such as the 2016 Dyn cyberattack and the 2020 SolarWinds breach, underscore the real-world impact of these vulnerabilities. The study concludes with actionable recommendations, including the adoption of zero-trust architectures, enhanced supply chain security, investment in advanced technologies like AI and blockchain, and the promotion of international collaboration. These findings have significant implications for policymakers, industry leaders, and researchers, emphasizing the need for robust regulatory frameworks, practical security measures, and ongoing research to address the ethical and privacy concerns associated with emerging technologies. This study contributes to the growing body of knowledge on telecommunications cybersecurity, offering a roadmap for enhancing network resilience in an increasingly interconnected and vulnerable digital world.
