GTP Attacks from RAN and Roaming
Security threats to the mobile network have escalated as cyberattacks grow in sophistication and volume and use lightly protected mobile and IoT devices in their botnets or targeted attacks.
GPRS Tunneling Protocol (GTP) is at the heart of providing seamless interconnection at multiple network interfaces. As traffic, devices and interconnection partners surge, so does the use of GTP. Attackers try to exploit vulnerabilities by abusing GTP interfaces exposed to the network. After collecting network information and subscriber identities, attackers can launch a number of different attacks against subscribers and operators. GTP is inherently insecure as it was not designed with security in mind.
Operators must now include a GTP firewall as part of their current network security posture and as they evolve the network to 5G.
