Abstract: Embodiments of the present disclosure discloses a method, an apparatus and a system for securing Network Functions (NFs) in a disaggregated network. The apparatus receives metrics and events related to one or more Network functions from an agent deployed in a host system. The apparatus validates the metrics and events by comparing with reference metrics and events. Further, the apparatus detects a threat in the disaggregated network based on the validation and performs one or more actions. The proposed solution helps in detecting an attack that originates from within a host machine of the disaggregated network, isolate the rogue NF and perform actions to protect the rest of the disaggregated network.

Abstract: A computer-implemented fraud detection system and method are disclosed. A method includes monitoring past customer account transactions conducted with a selected one or more transaction devices, and generating a predictive model that combines customer account transaction profiles with transaction device profiles related to the one or more transaction devices, and storing a representation of the predictive model in a storage. A system for detecting fraud in financial transaction includes a fraud detection computer that receives, through a communications network, customer account transaction data obtained by a monitoring device of a transaction device according to one or more transaction device variables of a transaction device profile.
