Question

Computer Security

Consider a desktop publishing system used to produce documents for various organizations.

a. Give an example of a type of publication for which confidentiality of the stored data is the most important requirement.

b. Give an example of a type of publication in which data integrity is the most important requirement.

c. Give an example in which system availability is the most important requirement.

Answer 1

a. Confidentiality: A publication for internal circulation and consumption for any organization needs the most confidentiality. This is even more applicable if the same system is producing documents for rival organizations (such as both Coca Cola and PepsiCo)

b. Integrity: Mostly publications involving data need to have the highest integrity. Publications involving maps need to be presented in a certain universal format. Another example could be related to publications of a certain dimension (such as a tabloid or a newspaper) which are almost always in a fixed dimension.

c: Availability: For the desktop publication system which is working online, availability is most important. Any number of users can come online at any instance and the system should be ready to address their requirements. [Example - Add-ons on a publication system which need to be downloaded. If many people start downloading them at the same time, their requests should be serviced simultaneously with least delay]
