Question 3 (20 marks)
Suggest the most appropriate security measures for each of the situations described below.
a. The Western Union bank uses an electronic funds transfer (EFT) system to transmit
sensitive financial data between its branches all over the world.
Answer:
This situation comes under the security measure of Encryption. Because transferring data
through the internet is a risky process, more security needs to be in place. Hence, data
needs to be encrypted before it is transmitted.
b. A fighter jet simulation company has set up an off-site computer-based training
centre for the F35. The company wishes to restrict access to the site to authorized
employees. Since each employee's use of the centre is occasional, it does not wish to
provide the employees with keys to access the centre.
Answer:
This scenario comes under the security measure of Authentication Schemes because
the process to restrict access to the site to authorized employees only requires a
verification step
c. A golf club uses a simple password system to protect its database. The club has
created a new Web site to allow both its members and its employees to use the new
Web-based system to access and update information. The club finds that it needs a
more comprehensive security system to grant different privileges (such as read-only
versus create or update) to different users.
Answer:
This situation comes under the measure of Authorization rules because it deals with
granting specific access levels to employees through the authorization process.
d. A training centre at the Northern Technical University has experienced
considerable difficulty with unauthorized users who access files and databases by
appropriating passwords from legitimate users.
Answer:
This situation comes under the measure of Authorization schemes because it deals with
unauthorized access issues to the database, hence dealing with verification steps.
