      Objectives:

      To enhance the learning capabilities of the students about:

      • CIA triangle.
      • OSI security architecture.

      Assignment

      Question No-1:
      In today’s IT world, different stores are running their businesses through Internet which enables their customers to make sales and purchase transactions online 24/7 from anywhere. Time saving is one of the prime benefits of online business/shopping as the customers don’t have to physically visit the business/shopping centers in this regard. In addition, online businesses also provide the facility of online support and tracking of their orders/transactions to their customers. The customers can get their queries clarified and can track their delivery status i.e. when the goods /products are going to be dispatched to them.
      However, in spite of all the benefits of online business/ shopping, still a large number of people hesitate to make online account on the website of online store to perform online transaction due to fear of losing their personal / account information. To ensure the customer gain, the online businesses must need to apply some OSI preventive security measures/services to tackle with the risk associated with their businesses.
      In view of above, you are required to carefully analyze each scenario given below and identify the most suitable OSI security service to tackle the risk associated with each scenario:

      Customer’s personal or order information is considered very important and it should be available only for that specific customer. Customer’s delivery address is stored in the database of an online store for delivery of required items. An employee of this store having legal rights to access this database, unintentionally changes this address information which resultantly can misguide the delivery of products on wrong address. Online shopping website is not accessible due to which its customers are unable to place orders or do any other transaction. Delivery receipt should be received in same form as it is sent to a customer. Online shopping store is going to launch new promotions, but this plan is leaked prior to its launching. While online shopping, customer is transferring online payment via credit card. Both the parties i.e. customer and related bank should be guaranteed for identification of each other. A customer is only allowed to see his/her order status, but not allowed to make any changes in his/her order information after successful submission of order request. A customer performs online order and then later denies for his/her order. How online business will tackle/handle this situation? A customer sends email to an online store to know about his/her order status and the online store replies to the customer with related information of order status. This information should be received as it is sent by online store.

      Solution:

      Scenario No OSI security service 1 2 3 4 5 6 7 8 9

      Question No-2:
      Consider an online performance evaluation system of a company where its employees enter the daily status of the tasks assigned to them in online sheets available in the system. The sheets are analyzed by the competent authorities of the company on daily basis to evaluate the performance of the employees.
      You are required to briefly explain the confidentiality, integrity and availability with the help of example associated with this system.
      In your point of view which component of C.I.A. Triangle model will get the highest importance and which component will get the least importance according to above mentioned scenario?

      Assignment
      Question No-1:

      “Friend Circle” is a social media platform yet to be launched. Currently, it is in testing phase in which various security policies in the perspective of an online platform are being tested. Following are the reports / observations of such tests:
      Report 1:
      Upon testing the login interface, the security experts found a loophole in the system that an unauthorized person can login to the system by trying different combinations of passwords.
      Report 2:
      It is observed that bundle of unnecessary requests possibly generated by some computers or bots can overload the application and resultantly system may crash or fail to perform ordinary functions.

      After carefully analyzing above mentioned reports, you are required to identify the type of attack associated with each report. Also mention one suitable solution to tackle the identified attack.

      Suppose a user receives an email containing an image file as the attachment. As the user opens the file, different files on his systems get deleted or modified. A student copied some files from his USB flash drive to a computer in university lab. After doing this, he observed that the number of files on the system got duplicated and overall performance of the system got deteriorated. He faced too much delay in performing tasks by the computer. A user noticed that someone is using his Facebook account after stealing his credentials. After investigation, he observed that it happened after installing a software downloaded from an un-authentic website.

      Question Description
      Scenario:

      Suppose “WeConnect” is an IT based company which is specialized in providing Voice over IP (VoIP) based services to its clients. Currently “WeConnect” is working on an application that will provide the functionality of “Virtual Labs” to Online Universities situated across the globe. Using this application the teachers could be able to give online lectures with the help of simulations and students could be able to raise text, audio or video based queries.

      A module of this application requires the usage of CAPTCHA codes that takes less than a minute to process, but the client is insisting to remove this delay for a better user experience.
