Title: SECURITY SYSTEM FOR SDN/NFV-BASED IP CALL SERVICE AND METHOD FOR OPERATING SECURITY SYSTEM
Abstract:
Disclosed are a security system and a security processing method for detecting whether an IP-based call service (VoIP or VoLTE) in an SDN and NFV environment is illegally used and blocking such an illegal use. A security system for an SDN-based centralized VoIP service comprises: a security service manager for setting and managing a security service policy necessary for using a VoIP security service; a VoIP security controller for generating the security service policy received through the security service manager, as a predetermined information model and delivering the generated information model to a VoIP security function; and at least one VoIP security function for providing the VoIP security service, on the basis of the information model received from the VoIP security controller. Therefore, it is possible to provide centralized and flexible services because the security service is provided by dynamically building the information model in a software-based SDN/NFV environment, without using an existing hardware-based security equipment.
