The digital computer is a key technology of the modern era and has been central and essential to key operations in modern industrial society, including manufacturing, transport and distribution, government, the military, health services, education and research. Their impact as instrument for technological growth will most likely increase over the next century. Due to the numerous applications of computer in daily activities, they are vulnerable to malfunction and misuse, creating problems such as computer crime, software theft, hacking, viruses, invasions of privacy, an over-reliance on intelligent machines and workplace stress, each of which has created one or more ethical dilemmas for the computer profession. This study therefore (i) discusses some of the fundamental aspects of ethical issues (such as privacy, computer crime, software piracy, and accessibility) in computer as an instrument of technology growth and its significance for the computer professional, (ii) evaluates the influence of computer ethics on technology growth from computer professionals' perspective and (iii) proposes solutions to ethical issues in computer through the help of practitioners who had excellent computer, information and communication technology background.
A pervasive network architecture that interconnect heterogeneous objects, devices, technologies and services called Internet of Things has prompted a drastic change in demand of smart devices which in turn has increased the rate of data exchange. These smart devices are built with numerous sensors which collect information from other interacting devices, process it and send it to remote locations for storage or further processing. Although this mechanism of data processing and sharing has contributed immensely to the information world, it has recently posed high security risk on privacy and data confidentiality. This paper therefore analyses different security threats to data at different architectural layers of Internet of Things, possible countermeasures and other in-depth security measures for Internet of Things. The paper identifies device authentication on IoT network to be of paramount importance in securing IoT systems. This paper also suggests some essential technologies of security such as encryption for securing IoT devices and the data shared over IoT network.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
