INFORMATION SECURITY
Question 1
Automated Teller Machine or an ATM is used for the purpose of withdrawing cash
without even visiting to the bank or without interacting with the bank staff members. Three
important requirements are present for the ATM card and the PIN. They are as follows:
i) Confidentiality: It is the other name for privacy and it helps to maintain the privacy
of the ATM card. Under no circumstances, the confidentiality of the card should be lost. The
user would major losses if this type of situation arrives (Peltier, 2013).
The degree of importance of confidentiality is high since, unsecured PIN during the
transactions can lead to the compromise of the bank account and therefore, encryption must
be present.
The examples of confidentiality in ATM system are as follows:
a) The details of the ATM card and PIN are extremely confidential and should not be
lost.
b) Presence of the ATM card while making a transaction is mandatory.
ii) Integrity: The data integrity is the next important requirement in ATM. The PIN
could be changed by the hackers and the users should ensure that this type of situation does
not arrive.
The degree of importance of integrity is high as if any hacker or thief gets hold of the
ATM card or PIN; they might change the data for the purpose of withdrawing money. Hence,
data integrity should be maintained properly.
The examples are as follows:
