Ethics are the moral principles by which we govern our lives. Ethics is an important part of society because without it, the general population we call society would behave no better than the general population in prison. That said, ethics in computing and information systems concerns the behaviors considered acceptable by users and the functionality of the system used. Information passing through an information system must be handled ethically to ensure the security of the user and sensitive information. In addition to ethical management, users of information must use the system ethically and systems must be designed to protect against unethical use. Computers and information systems are constantly evolving, changing the way we do business and interact in the world. In the early 1990s it was said: “In the relatively short space of forty years, computers have become essential to the functioning of industrial societies” (Forester, 1994, p. 1). This is remarkable because in a short time we have witnessed not only the evolution of computers, but also the system of ethics and policies that govern their use. With the widespread use of computers and their increasing access, new ethical dilemmas arise. The nature of these dilemmas ranges from computer crime to intellectual property and copyright infringement. Data contained in computer information systems must be handled ethically for the security and privacy of those using the system. For example, PayPal, a system designed to make secure transactions, stores credit card and banking information online. What would happen if PayPal did not take into account the ethics and security of the information stored in its databases? The information stored in middle of paper....... We can limit what the computer or system does, we can give it rules or a specific task to do so that it is not able to perform outside of these rules. How to determine what data is necessary for the system to function. What makes collecting this data good or bad? This is how these data are used.BibliographyForester, TM (1994).
