Network Infrastructure & 5G Security
Telecommunications networks are the backbone of global connectivity, carrying voice, data, and critical services. With the rollout of 5G, the attack surface expands exponentially – from virtualized core functions to billions of IoT devices. Nation‑state actors and cybercriminals target SS7, Diameter, and 5G signaling protocols to intercept communications, commit fraud, and disrupt services.
Rezolute specializes in securing telecom infrastructure with 5G security, signaling protection, and defense against large‑scale DDoS and fraud attacks.
TOP THREATS TO TELECOMMUNICATIONS
Flaws in SS7, Diameter, and 5G signalling allow attackers to intercept calls, track subscribers, bypass authentication, and commit fraud. These protocols were designed for trust, not security.
Attackers can move laterally between slices, compromising critical services (e.g., emergency services, smart grids) if slice isolation is not properly enforced.
Virtual network functions running on shared infrastructure introduce new risks – hypervisor escapes, insecure APIs, and configuration drift can lead to core compromise.
Telecom networks are prime targets for volumetric DDoS attacks that saturate bandwidth and disrupt connectivity. 5G’s high bandwidth also enables larger amplification attacks.
Billions of unsecured IoT devices connected via 5G can be recruited into botnets or used as entry points into the network. Edge nodes also become attack vectors.
Failure to meet national security requirements (e.g., lawful intercept, data sovereignty) can result in heavy fines and loss of operating licenses.
COMPLIANCE & REGULATORY LANDSCAPE
HOW WE PROTECT TELECOMMUNICATIONS
We help operators secure 5G standalone (SA) and non‑standalone (NSA) networks. Our services include signalling firewall deployment, protocol vulnerability assessment, and slice isolation testing to prevent lateral movement and signalling attacks.
Protect SS7, Diameter, and 5G HTTP/2 interfaces from spoofing, interception, and fraud.
Verify isolation between network slices to prevent cross‑slice attacks.
Identify vulnerabilities in 5G core network functions (AMF, SMF, UPF).
As networks virtualise, the attack surface expands. We secure NFV infrastructure, orchestration, and VNFs through hardening, continuous monitoring, and compliance with ETSI NFV‑SEC standards.
Secure hypervisors, containers, and management interfaces against compromise.
Configuration reviews and vulnerability assessments of virtualised network functions.
Protect orchestration and management layers from unauthorised access and tampering.
Large‑scale DDoS attacks can cripple telecom infrastructure. We design and implement multi‑layer DDoS protection, from on‑premise scrubbing centres to cloud‑based mitigation, ensuring service continuity.
Architect and deploy on‑premise DDoS mitigation capable of handling multi‑terabit attacks.
Resilient DNS infrastructure to absorb attacks and maintain resolution.
Real‑time traffic monitoring and automated mitigation using BGP Flowspec.
With 5G enabling massive IoT, securing endpoints and edge nodes becomes critical. We help implement device authentication, secure onboarding, and edge node hardening to prevent botnets and data breaches.
Secure provisioning and authentication of massive IoT devices using SIM‑based or certificate‑based mechanisms.
Secure configuration of MEC (Multi‑access Edge Computing) platforms and applications.
Continuous monitoring of IoT traffic for anomalies and botnet activity.
