Signaling attack prevention method and apparatus

Abstract

A signaling attack prevention method and apparatus is provided. The signaling attack prevention method can include receiving a Diameter request message sent by a mobility management entity (MME) or a serving general packet radio service (GPRS) support node (SGSN); and determining whether the Diameter request message is received through a roaming interface. When the Diameter request message is received from the roaming interface, the signaling attack prevention method can include determining whether a characteristic parameter of the Diameter request message is valid; and if the characteristic parameter of the Diameter request message is invalid, the method can include discarding Diameter request message or returning, to the MME or the SGSN, a Diameter response message carrying an error code. In this way, a hacker can be effectively prevented from attacking an HSS or an edge node by using each attack path, and communication security is improved.
