Abstract

Voice-over-IP (VoIP) technology revolutionised telecommunications through inexpensive and flexible communications. Its growing user base worldwide across various sectors, including business, healthcare, and telecommunications, originates from the rising demand for VoIP services, which exposes VoIP systems to multiple threats. RiVS combines a reputation system based on the Alpha-Beta distribution to further enhance the security of VoIP systems to protect against toll fraud, authentication attacks, and Spam over Internet Telephony (SPIT). RiVS is integrated with the Asterisk server (known as IP PBX or VoIP server) operating as an intermediary between the VoIP server and the reputation system. RiVS is able to parse user authentication or call attempts to determined if they should be flagged, dropped, or allowed through the system. The reputation system keeps records of positive and negative actions. Experimental procedures were conducted to evaluate system resources usage and response time. With results showing actions performed promptly with few system resources, for consideration of cloud and on-premises deployments.
