Abstract
Provided are a system and method for preventing the intrusion of an abnormal GPRS tunneling protocol (GTP) packet. The system includes: a system management unit including a monitoring unit which monitors a state of the system and a mode changing unit which changes an operation mode of the system based on the state of the system; a packet capture unit including a packet management unit which stores information about a GTP packet based on the operation mode of the system and a detection result checking unit which determines whether to drop the GTP packet; and a packet detection unit including a packet parsing unit which parses the information about the GTP packet and a packet analysis unit which analyzes the parsed information about the GTP packet, wherein the operation mode of the system is an intrusion prevention system (IPS) mode or a bypass mode.
