Title: METHOD AND DEVICE FOR PREVENTING SIGNALING ATTACK
Abstract:
Disclosed in the embodiments of the present invention are a method and device for preventing signaling attack, the method comprising: receiving a diameter request message sent by a mobile management entity (MME) or a serving general packet radio service (GPRS) support node (SGSN); determining whether the diameter request message is received from a roaming interface; determining whether feature parameters of the diameter request message are valid when the diameter request message is received from a roaming interface; and discarding the diameter request message or returning a diameter response message carrying an error code to the MME or the SGSN if the feature parameters of the diameter request message are invalid. Thus, a hacker attacking a home subscriber server (HSS) or an edge node using each attack path may be effectively prevented, and communication security is increased.
