2INFORMATION SECURITY
Answer to Question 1:
The CIA trait can be considered as a basic guideline, which is related to ensuring the
security of data. The concept deals with how data can be secured saved without any third party
involving into the data. In this scenario, it can be stated that the PIN can act as a security aspect
in the framework of working which is involved into the ATM. The PIN can be considered as an
identification number, which can be used for conducting transaction over the system. In order to
achieve the desired standard of security the personal who are involved into the process should
achieve adequate amount of training so that they would be helpful in the concept of mitigation of
the problem when it occurs (Prasanthi et al., 2014)
Answer to Question 2:
In this question a situation is given in which a theft broke into the ATM by means of a
screwdriver. He was able to jam the card reader and eventually break five keys of the machine.
The thief in the process had to halt due to the factor a user was approaching to use the machine.
The customer entered the card but was not able to do any type of transaction. Therefore, he went
out to get help. In the meanwhile, the theft again entered the room and started to hint the
password or the PIN. In this question, we are to undertake the maximum amount of number the
PIN can be entered by means of using the permutation technique of the mathematics. The total
number of keys, which are present in the system, is ten out of which five keys were broken.
Therefore the number of keys which would be available for guesswork is five keys so that they
four digit password can be achieved.
5P4 = 5! / (5-4)! = 5! /1! = 5*4*3*2*1/ 1 =120/1 =120.
