A method for detecting and mitigating security attacks on producer NFs using error response messages includes tracking, by a proxy NF, rates of error response messages generated in response to inter-PLMN SBI request messages from consumer NFs. The method further includes receiving an inter-PLMN SBI request message, obtaining information for identifying a consumer NF and a producer NF from the inter-PLMN SBI request message, and determining that a rate of error response messages generated in response to inter-PLMN SBI request messages from the consumer NF to the producer NF exceeds a threshold rate. The method further includes, in response to determining that the rate of error response messages generated in response to SBI request messages from the consumer NF exceeds the threshold rate, performing a network security action.
