Total 100 marks for this Assignment 1:
In this assignment, you are required to complete the following three activities. Clearly state any assumptions you make. Your assumptions should be consistent with what are given the descriptions below. Upon the completion of the activities, you are required to provide a formal report documenting your findings in a single PDF file.

Three Activities (CYB5CYA)
Please consider the following application scenario using Australian My Health Record (MHR) system.
A simple MHR scenario:
MHR is an initiative by the Australian government that provides a secure online summary of the health information to the individuals (e.g., health professionals and patients). It can control what goes into it and who is allowed to access the MHR system. It can choose to share patients' health information with their doctors, hospitals and other healthcare providers like pharmacists. In addition to such "primary use" of the data/information for the health services, there are plans to use aggregated and anonymized health data/information for research health information securely in one place. It is really our choice - we can keep our MHR with
basic information, or we can allow more information to the MHR system or permanently delete the record. An MHR user is an individual who has right to use patients' health information. For example, A Doctor can do the following actions in the MHR system: Login to the system, Access patients' health information, Write prescription, Recommend patient to the specialists.

Please follow the word limits that are mentioned in each activity.
Activity (1)- Write any specific use case description of the MHR system and identify the misuse cases. In this activity, you should document your findings according to following:

  •  Identify at least 5 use cases that can allow different users to interact with MHR system
  •  Identify the possible misuse cases for those use cases (at least 5 misuse cases) 
  •  Select a single use case and provide the situations (i.e., a situation is seen as interactions between actors and system) for your selected use case – 15 marks
  •  Write the description of the selected use case 

You may need to make your own assumptions for the situations that are not included in the above-mentioned MHR scenario. In this case, state your assumptions.
Note: you can use one or more of these tools for documenting the description of your use and misuse cases: 
(i) flowchart, 
(ii) UML use case description and diagram, 
(iii) other systems/tools.
