The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate.
A method of detecting cyber-attacks using network analytics in a user equipment (UE) is provided. The method includes receiving, by a network data analytics function (NWDAF), a request for sharing analytics information associated with the UE from a consumer network function (NF), requesting the analytics information associated with the UE and causing the cyber-attack to at least one 5th generation core (5GC) network entity, receiving the analytics information associated with the UE and causing the cyber-attack from the at least one 5GC network entity, comparing an expected behavior of the UE with an actual behavior based on the analytics information provided by the at least one 5GC network entity, deriving analytics associated with the cyber-attack based on the analytics information and the comparison, and sending the analytics associated with the UE to the consumer NF.
