Securing Telecom Platforms Across Legacy and 5G Networks

Telecom operators face growing cybersecurity pressure as 5G, IoT, AI-driven automation, and cloud-native infrastructure expand the attack surface across critical communications environments. This analysis examines how vulnerabilities emerge across OSS/BSS platforms, network orchestration systems, SIP and IMS infrastructure, cloud-native network functions, and customer-facing applications. It outlines practical approaches for maintaining resilience through zero-trust access models, secure CI/CD pipelines, API hardening, observability, and telecom-specific anomaly detection. For technology leaders, the challenge is no longer securing isolated components, but maintaining operational continuity and trust across highly interconnected telecom ecosystems.
