Embodiments of present disclosure relates to an apparatus and method for managing security context related to a UE. Initially, registration of a UE with a new AMF in a communication network is identified. Further, generation of new security context by new AUSF selected by the new AMF for authentication of the UE is detected. Further, presence of one or more old security contexts elated to the UE and generated by one or more old AUSFs selected by one or more old AMFs for one or more previous authentications of the UE, is detected. Upon the detection, de-registration of the UE with the one or more old AUSFs is initiated for managing security context related to the UE in the communication network. Thus, stale and inactive security context related to the UE may be deleted in the network and security of communication with the UE is enhanced.
