Forum for Uniting Security Experts in 5G

Mobile networks play a critical role in our interconnected world, enabling seamless communication, data exchange and access to a wide range of services. One of the most important considerations in the area of mobile networks is security, given the increasing reliance on these networks for various aspects of our daily lives. As mobile devices become more integral to our personal and professional activities, the protection of sensitive information and the prevention of unauthorised access have become paramount. Establishing a dedicated forum where professionals from across industry, academia and government can come together to discuss the current state of mobile network security is critical to addressing emerging threats and vulnerabilities. This collaborative platform facilitates the exchange of insights, research findings and best practices, fostering a collective effort to improve the robustness of mobile network security. FUSE5G aims to foster a collaborative mobile network security community in Europe by providing a dedicated platform for researchers and industry professionals to share insights, discuss emerging threats, and collectively enhance the security measures of 5G networks.

The FUSE5G initiative will be kickstarted with a community event in Bochum, Germany on Tuesday February 4th 2025. Presenters from industry and academia will share a varied perspective on developments in mobile network security. The program is outlined below and includes ample opportunity to network with fellow security professionals. Participation is free of charge but we kindly request that you register upfront in view of limited capacity.



Program

10:00 Opening
10:10 Keynote: Mikko Karikytö, Head of product security at Ericsson
Fortifying the Future: Navigating 5G Security to unleashing an era of limitless potential

Mobile networks have revolutionized our world in profound ways. From 2G to 4G, we've witnessed the digital transformation with the advent of mobile internet, a flourishing app economy, and the enablement of IoT and platform-based business models—cornerstones of our contemporary digital ecosystem. As we transition to 5G, the stakes are higher than ever. This next-generation technology promises to unlock unparalleled value to new sectors of the society. However, with great potential comes great risk. As our reliance on these networks intensifies, our tolerance for disruptions and security breaches diminishes, rendering these systems critically vital. In my keynote, I will explore the pivotal role of security in the era of limitless potential facilitated by 5G. We will delve into strategic approaches to fortify these essential networks against an increasingly complex threat landscape, ensuring robust, resilient and privacy persevering digital infrastructures for tomorrow’s world. Join me as we navigate the intricate interplay of innovation and security at the heart of the mobile revolution.

Telecoms and 5G: Why Standardization is Easier Said Than Done

The rollout of 5G has brought significant advancements in connectivity, but it has also exposed critical challenges for telecom operators when implementing standardized technologies in the interconnect domain. A key issue is the adoption of Security Edge Protection Proxy (SEPP) for secure communication between carriers, raising questions around the balance between encryption and operational transparency requirements from carrier side. While encryption ensures robust security, it introduces complexity for operations teams, who face difficulties in monitoring, debugging, and maintaining seamless interoperability. The tension between maintaining carrier-to-carrier transparency and adhering to strict encryption standards has become a focal point of industry-wide discussion. This presentation explores the operational pain points caused by SEPP implementation, the trade-offs between carrier plaintext data and encryption, and the inherent limitations of current standardization approaches. Additionally, it looks ahead to 6G, discussing how future generations can learn from the 5G experience to create more efficient, adaptable, and operator-friendly standards. By addressing these challenges proactively, the telecom industry can better navigate the evolving landscape of interconnect technology and secure communication.

12:00 Talk 2: Alf Zugenmaier (Vice Chair 3GPP SA3, Munich University of Applied Sciences)
M5GA - 6G making 5G great again?

With the standardisation of 6G in 3GPP around the corner, maybe it is time to take a step back to look at 5G security design and where there would be potential for improvements.

12:30 Lunch Break
13:30 Talk 3: Ravishankar Borgaonkar (SINTEF)

Abstract

14:00 Talk 4: Folkert Saathoff, Security Research Labs
The Pentester Perspective: Mobile Network Security in 2024

When conducting penetration tests of mobile networks, we found that many known vulnerabilities, eg in SS7 signalling, now seem well understood and mitigated against. However, hybrid 4G / 5G NSA architectures and new interfaces like OpenGateway provide new opportunities to malicious parties, and hence new challenges to operators and vendors. In this talk, we will give an overview of the realities we observed when evaluating the IPX and RAN interfaces of mobile network operators.

14:30 Coffee Break and Poster Session
15:00 Panel
A panel of experts will discuss current topics in the context of 5G security and the potential of further community collaboration.
16:00 Drinks
