Trends in Telecommunications and Networking in Secure E-Commerce Applications
Abstract
Telecommunications and networking, two prominent technologies of the information age, have enjoyed substantial investments from industry and government, resulting in unparalleled growth in the transmission of voice, video, and data over wired and wireless media. Since their inception several decades ago, these technologies and their business applications have progressed through several stages. Such progression commenced from the development of the primitive electronic funds transfer (EFT) in which funds could be transferred electronically, to the enormous variety of technologies available today. Several decades ago, the delivery of video, voice, and data was accomplished through three independent networks: television, telephone, and data networks, respectively (Panko, 2007). Today, a convergence of the three networks is occurring. For example, networking technology can deliver video, data, voice (through VoIP), graphics and other multimedia contents at considerable speed. Currently, there are many applications associated with telecommunications and networking technologies. They include electronic mail (e-mail), voice over Internet protocol (VoIP), and videoconferencing. Also, the Internet which was built on the world-wide telecommunications and networking infrastructure gave rise to many applications such as electronic commerce (e-commerce), electronic data interchange (EDI), and several other World Wide Web (Web) applications. Electronic commerce, which is the process of buying, selling, or exchanging products, services, and information via computer networks, has evolved and become an ever-booming enterprise. The advent of broadband digital subscriber line (DSL) and broadband cable has enabled the transmission of data signals through telephone and cable-television (cable-TV) networks. Moreover, broadband technology has made high speed Internet access very affordable for small businesses and individuals. It has also facilitated e-commerce by providing businesses and consumers easy access to the global information super highway. The fact that e-commerce transactions involve the transmission of personal and organization’s proprietary information over the unsecured Internet, make them easy targets for hackers. Therefore, security of electronic communications is a major problem that must be addressed by organizations that engage in e-commerce. This article presents the trends in telecommunications and networking; security problems confronting such technologies and related e-commerce applications; and the management of security issues associated with these technologies.
