Application: Securing control and user plane separation in mobile networks (Patent ID: US20230412566A1)
The patent filed by Palo Alto Networks Inc. discloses techniques for securing control and user plane separation in mobile networks, specifically for 4G and 5G networks. The system described involves monitoring network traffic to identify Packet Forwarding Control Protocol (PFCP) messages associated with new sessions, extracting parameters from these messages, and enforcing security policies based on these parameters to ensure the separation of control and user planes in the mobile network. The security platform is designed to build sessions, create session state machines, and perform sequence number checks to prevent unauthorized access and attacks such as spoofing or session hijacking.
The system, method, and computer program product outlined in the patent focus on extracting specific parameters from PFCP traffic, including source and destination IP addresses, Session Endpoint Identifiers (SEID), and protocols in use, to establish and secure sessions in the mobile network. By enforcing security policies that only allow authorized messages between control and user planes and performing sequence number checks, the platform aims to enhance network security by preventing unauthorized access and potential attacks. Additionally, the system is capable of detecting and preventing spoofing and session hijacking attacks, blocking or allowing new sessions based on the security policy in place, thereby ensuring the integrity and security of the mobile network, particularly in the context of evolving 4G and 5G networks.
