Abstract
Voice over internet protocol (VoIP) provides cost-effective phone service over a broadband internet connection rather than analog telephone services. While VoIP is a fast-growing technology, there are issues with intercepting and misusing transmissions, which are security concerns within telecommunication organizations and for customers. Grounded in the routine activity theory, the purpose of this multiple case study was to explore strategies information technology (IT) security managers used to secure VoIP telephone systems in telecommunication organizations. The participants consisted of nine IT security managers from three telecommunication organizations in New York who possessed the knowledge and expertise to secure a VoIP telephone system. The data were collected using semi structured interviews, note taking, and one document from one organization. Four themes emerged from the thematic analysis: best practices for VoIP security, using a secure VoIP provider, VoIP security recommendations, and awareness of future security concerns. A key recommendation for IT security professionals is to ensure encryption to secure a VoIP telephone system. The implications for positive social change include the potential for IT security managers and telecommunication organizations to reduce data breaches and the theft of their customers’ identities and credit card information.
