3. Network infrastructure
Networks combine radio access, fibre transport, IP routing, DNS and a core that is increasingly cloud-native for 5G. Network elements are managed remotely by operations teams and vendors through element managers and support connections—making privileged access and configuration integrity central to security.
4. Subscriber, enterprise and IT systems
Subscribers are onboarded through KYC at retail points and digital channels, served by CRM and billing (OSS/BSS) systems, and identified by SIMs that also deliver banking OTPs. Enterprise customers rely on managed SD-WAN and security services run by the provider.
|
Highest-risk moments SIM replacements, vendor support sessions, network configuration changes and OSS/BSS administration are where telecom fraud and cyber attacks do the most damage. |
