Abstract

The embodiment of the present invention discloses a method and device for preventing signaling attacks. The method includes: receiving a diameter request message sent by a mobile management node (MME) or a serving general packet radio service (GPRS) support node (SGSN); judging Whether the diameter request message is received from a roaming interface; when the diameter request message is received from a roaming interface, determine whether the characteristic parameter of the diameter request message is legal; if the characteristic parameter of the diameter request message is not legal, then discard The diameter request message or return a diameter response message carrying an error code to the MME or the SGSN. Therefore, it can effectively block hackers from using various attack paths to attack the HSS or edge nodes, and improve communication security.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for preventing signaling attacks. Background technique [0002] A Mobility Management Entity (MME for short), a Serving GPRS Support Node (SGSN for short), and a Home Subscriber Server (HSS for short) are all important network elements in a mobile communication network. Among them, the MME is responsible for the signaling processing part, the SGSN mainly completes the routing and forwarding of packet data packets, mobility management, session management and other functions, and the HSS is used to support the IP Multimedia Subsystem (IP Multimedia Subsystem, IMS for short) for handling calls / sessions. ) the main user database of the network entity. [0003] In the 4th Generation mobile communication technology (4G for short) network, the communication between MME (SGSN) and HSS is based on the DIAMETER protocol, and in order to improve performance in actual networkin...
