 VoLTE Security Training by TONEX

VoLTE Security Training covers all VoLTE security and insecurity aspects of voice, video and multimedia solutions in LTE, EPC and IMS networks. Voice over LTE (VoLTE) is an integrated and essential foundation for the future of mobile service provider business models in transition from 2G and 3G networks to LTE and VoLTE. Migration to VoLTE will have performance, interoperability, security, signaling, and billing challenges for the mobile operators and need to be addressed.

TONEX VoLTE Security Training provides essential knowledge and skills for engineers and non-engineers who are concerned on LTE, EPC, IMS and  VoLTE security, insecurity and performance.

VoLTE (Voice-over-LTE) as the designated voice solution to the LTE mobile network using EPC and IMS networks has to address VoLTE security before full rollout. Learn about several vulnerabilities in both LTE, EPC and IMS control plane and user plane functions, which can be exploited to disrupt both data and voice services in operational networks.

Learn how to validate attacks using commodity smartphones/UE (rooted and unrooted) in international mobile carriers: UE OS and chipset, prohibit non-VoLTE apps from accessing, injecting packets into VoLTE control and data planes, IPv6 attacks and more. Does LTE, EPC, IMS network infrastructure lacks proper access control and runtime check?

Who Should Attend?

IT managers, network engineers, telecom managers, security managers, IT auditors, project managers, analysts, security engineers, security administrators, or any technical professional working with or planning to work with commercial and government based VoLTE technologies including: Security professionals, incident handling teams, penetration testers, auditors, network security planning teams, network administrators, IT and telecom engineers, and IT security management. This course is also beneficial for the homeland security community, DoD and crime prevention/investigation officers.
