**Exploring O-RAN Security**

**\[Webinar #10 – Thursday, July 3 | 16:00–17:00 CET]**

Open RAN (O-RAN) is rapidly gaining traction as a transformative approach to building mobile networks—bringing promises of cost efficiency, vendor interoperability, and innovation through open interfaces and disaggregated components. But while the benefits are clear, the security implications are far from fully understood.

In this technical webinar, P1 Security’s telecom security expert **Kye Grundy** explores the hidden risks and threat surfaces emerging from O-RAN deployments. We will cover real-world vulnerabilities affecting the O-DU, O-RU, and O-CU components, security gaps in interface protocols like E2 and A1, and how attackers may exploit orchestration layers and multi-vendor integration points.

You’ll also gain clarity on:

*   Common security misconfigurations in Open RAN deployments
*   The evolving threat landscape for disaggregated RAN architecture
*   Lessons learned from recent security assessments and testbeds
*   Recommendations for telecom operators and systems integrators looking to harden their O-RAN infrastructure

Whether you're involved in 5G rollouts, network security architecture, or vendor management, this session will help you understand how Open RAN security is reshaping the risk profile of mobile infrastructure—and what can be done to stay ahead of attackers.
