Question

Consider an automated teller machine (atm) in which users provide a personal identification number (pin) and a card for account access. Give examples of confidentiality, integrity, and availability requirements associated with the system and, in each case, indicate the degree of importance of the requirement.

Answer 1

Confidentiality of personal PIN, availability of bank services to the user and integrity of the information in the ATM card from the bank server.

Step-by-step explanation:

Confidentiality is the process of preventing outsiders from seeing the details of the user of an account. The PIN and ATM card is a two factor authentication process to allow only the user of the account to view the bank details.

Availability of the bank information is based on the bank services to provide a constant supply of the information or services requested by the user.

Integrity justifies the originality and quality of the information from bank server to the user in the ATM machine session.
