METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR DETECTING AND MITIGATING SECURITY ATTACKS ON PRODUCER NETWORK FUNCTIONS (NFs) USING MAPPINGS BETWEEN DYNAMICALLY ASSIGNED SERVICE-BASED INTERFACE (SBI) MESSAGE IDENTIFIERS AND PROXY NF IDENTIFIERS AT PROXY NF

Abstract: a method for detecting and mitigating security attacks on producer network nf using mappings between dynamically assigned sbi message ids and proxy nf ids includes, at a proxy nf, automatically creating a database of mappings between proxy nf ids and sbi message ids comprising resource ids dynamically assigned by producer nfs in response to request messages from consumer nfs. the method further includes using the mappings to validate received inter-plmn sbi request messages and performing network security actions for the received inter-plmn sbi request messages for which validation fails.
