Answer:
Examples of confidentiality:
The channel of communication between the Bank and Automated Teller Machine must be encrypted. The personal identification number (PIN) of the ATM'S Card must also be encrypted as well, if stored
Examples of integrity:
The actions accomplished through the Automated Teller Machine must be linked to the bank account link with the ATM Card
Examples of availability requirements:
At any time, the Automated Teller Machine system must serve at least X concurrent bank users. The ATM system must be available at most 99.99% of the time.
When using an automated cash deposit machine in which users are required to provide a card or an account number to enable them to deposit cash, important considerations center around the issues of confidentiality, integrity, and availability.
In each of these essential requirements, we shall indicate the degree of importance attached while giving some examples.
Confidentiality: Users require that their ATM's cards bear encrypted personal identification numbers (PIN) with security codes that add some layer of confidentiality. No card user would like personal information to be leaked through the machine. Thus, the ATM operator must ensure that communication with the machine is restricted to the users and its system without unauthorized access to bank staff and other users. Card or account users expect the highest degree of confidentiality with the operation of the machine.
Integrity: Users require that the machines are not prone to errors. It does not bode well when a user deposits some cash while the machine debits (instead of crediting) the user's account. The accounting of transactions must not compromise integrity and confidentiality. There is a high degree attached to the importance of system integrity.
Availability: Users of ATM deposit machines would prefer that the machines are operational, 24/7, with minimal or non-existent technical interruptions. Availability requirements include ensuring that the machines are also provided at many convenient places with physical security. The degree of importance attached to availability is not as high as that required for system integrity and operational confidentiality.
Thus, confidentiality, integrity, and availability are important requirements for any automated cash deposit machine because the users attach high levels of importance to these requirements.
