1. A method for performing a location and velocity check at a security edge protection proxy (SEPP) to protect against a spoofing attack, the method comprising:
receiving, at an SEPP, a service-based interface (SBI) request message relating to authentication of a user equipment (UE);
querying, by the SEPP, a database network function (NF) to obtain previous authentication information for the UE, the previous authentication information including a previous network identifier and a previous authentication time for the UE;
receiving, at the SEPP, a response from the database NF, the response including the previous network identifier and the previous authentication time;
reading, by the SEPP, a current network identifier from the SBI request message;
performing, by the SEPP and using the current network identifier from the SBI request message, the previous network identifier, the previous authentication time, and a time of receipt by the SEPP of the SBI request message, a location and velocity check for the UE; and
performing a network security action for the SBI request message based on results of the location and velocity check.
