GTP-User Plane
GTP-USER (GPRS Tunneling Protocol - User) is a protocol used in mobile networks to carry user data. It is essential for enabling mobile internet services by encapsulating user data and transmitting it over the network. This protocol is a key component in the functioning of mobile data services.
What is GTP-User Plane
GTP-USER (GPRS Tunneling Protocol - User) is a protocol used in mobile networks to carry user data. It is part of the GPRS (General Packet Radio Service) core network architecture, which allows mobile devices to access internet services. GTP-USER operates over UDP and is used to encapsulate and transmit user data between different network nodes.
The protocol is essential for the functioning of mobile data services, as it enables the transfer of user data from mobile devices to the internet and vice versa. This encapsulation allows for efficient and secure data transmission, ensuring that users can access internet services seamlessly while on the move.
GTP-USER is widely used in 2G, 3G, and 4G networks, and continues to be relevant in the context of 5G networks. It plays a crucial role in the overall performance and reliability of mobile data services, making it a critical component of modern telecommunications infrastructure.
GTP-User Plane runs on TCP and UDP port 2152 and is official IANA port.Security risk
If port 2152 is open and the GTP-USER service is running, it could be exploited by attackers to intercept or manipulate user data. This could lead to data breaches, unauthorized access to sensitive information, and potential service disruptions. Proper security measures, such as firewalls and intrusion detection systems, should be in place to mitigate these risks.
In our UFW tutorial you can follow instructions how you can configure UFW to close port 2152. Use StackChanges to monitor if the GTP-User Plane port is closed and stays closed. StackChanges will send an alert if port 2152 is open again.
