METHOD AND DEVICE FOR PREVENTING SIGNALING ATTACK
Document Type and Number:
WIPO Patent Application WO/2018/040565
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present invention are a method and device for preventing signaling attack, the method comprising: receiving a general packet radio service (GPRS)-based tunneling protocol (GTP-C) message sent by a serving gateway (SGW); determining whether the GTP-C message is received from an S8 interface; determining whether a first feature parameter of the GTP-C message is valid when the GTP-C message is received from an S8 interface, the first feature parameter comprising at least one of the following parameters: an identifier of a message source end of the GTP-C message and an international mobile subscriber identity (IMSI) of a user; and discarding the GTP-C message or returning a GTP-C response message carrying a reason value of an error code to the SGW if the first feature parameter of the GTP-C message is invalid. Thus, a hacker attacking a public data network gateway (PGW) using each attack path may be effectively prevented, and communication security is increased.
