SECURITY FUNDAMENTALS2Question 1ConfidentialityThe user will utilize their card PIN to access their bank accounts on the ATM.It is expected that the PI is confidential on the system and also during the transaction in the communication channel (Tchernykh, Schwiegelsohn, Talbi & Babenko, 2016). During transitbetween the server and the host ATM.For this case, the degree of importance of confidentiality goes to the extent which unsecure PIN used to perform transactions may lead to the account being compromised. For this reason, the PIN must be well encrypted in a secure transaction.IntegrityThe ATM user anticipates that the transaction he or she is performing goes well without any accidental changes.The degree of Integrity: The system must always be correct in all calculations on the money. All withdrawals must be deducted correctly without any mistakes. Therefore, the integrity of transactions must be kept since any transaction will directly affect the customer.AvailabilityThe ATM must at all times regardless of any circumstance be available to every customer(Tchernykh et al., 2016).The degree of availability: The ATM being always operational and serviceable will improve the bank’s economic growth.

SECURITY FUNDAMENTALS3Question 2.The thief needs to enter a 4 digit pin. In a digit, he can only enter a maximum decimal of 10; that is entering either 0,1,2,3,4,5,6,7,8 or 9.Now, the maximum pins he is required to enter is equaled the number of decimals he can provide in each digit in every one of the four digits. For instance, if the four digit number is ABCD, the thief can only provide 10 possible decimals in every of the four digits. That is, 10 in A, B, C and in D.Finally, the total number of pins required will be:10*10*10*10 = 10000.Question 3.Utilizing biometrics can be daunting if you have more than one person to use the system. One person will be called every time to help in logging into the system.Second, biometrics can be very expensive since its market is still somehow fractured. One would have to purchase a fingerprint scanner, an iris scanner or a voice recognition framework as different products from different vendors (Alsaadi, 2015).People also understand that biometric data just like any other kind of data is stored on servers. If the servers are not well secured, they can be vulnerable to attacks.Accuracy – It is true that biometrics can fail to validate the details of a person on many occasions. Many people would shy away from this and just implement password protection mechanisms.
