Penetration Testing for Telecommunications
Telecommunications providers operate critical infrastructure that enables global communications, including mobile networks, fixed-line networks, internet service provision, and cloud communications platforms. Telecom operators are targeted by nation-state actors seeking intelligence collection, cybercriminals exploiting billing systems, and attackers targeting the infrastructure that other industries depend upon.
Penetration testing for telecom must cover a vast and diverse technology landscape including core network infrastructure, customer-facing portals and apps, billing and CRM systems, OSS/BSS platforms, 5G infrastructure, and interconnection points with other operators. Telecom-specific testing may include SIP/VoIP security testing, SS7 vulnerability assessment, and testing of mobile network components.
The deployment of 5G networks, network function virtualisation (NFV), and software-defined networking (SDN) has introduced new attack vectors that require testing by specialists who understand telecom architectures. Telecom operators in Europe must comply with NIS 2, the European Electronic Communications Code, and national telecom security regulations.
