The most important features for businesses would be confidentiality, access control, integrity and availability. The selected few were chosen given that the nature of the business is an online magazine and they were also chosen because a good designer should be able to derive others. It also said that the user will have to choose a username and password, so access control is mandatory. Confidentiality Confidentiality is essential for the online magazine because the same consideration given to the magazine should be given to the customer. From a customer perspective, you don't want to subscribe to a company where someone else, whether in the magazine or elsewhere, can access your private information. For example: a client has a friend who works for the magazine. Suppose this friend (the employee) wants to see what his friend (the customer) subscribes to? Not all employees should be entitled to this information. In fact, no one should do it unless necessary. Therefore, the magazine's policy must determine who has privileges over information, which clearly demonstrates how confidentiality can result in access control. From the magazine's perspective, if unauthorized access to information is allowed, whether it be customer information or editorial content, the company will stop generating revenue because no one will be willing to risk subscribe knowing that their information will be collected and probably misused, such as if their email is accessed and their inbox is spammed or in the event that the site itself is not secure and any programmer amateur can write a script to grant themselves and others access to the site's content without having to pay, again lost revenue...... middle of paper .... ..ml5Jhnri4, J.
