SBD403 - Secure by Design & Executable Development - IT Assignment Help

Assignment Task -           

Task Summary 

You will be provided with a Microsoft excel .csv file. This file contains a large volume of data.  You must develop an executable that respects the permissions and rules that the file has  been created with. There are several possible rules that each cell or section can have, and  they will be detailed both below and within the sheet itself. 

This program should be able to read and write to the .csv file, as well as support multiple  levels of user access (Guest, User, Superuser, and Administrator). Security information,  terms, and definitions are detailed below in the Task Instructions.  

This assessment has 4 weeks allocated, and is due on the final day of the module. 

Context 

One of the fundamental, core concepts of Security through Design is the separation of  functionality into different roles. This assessment follows that separation. Many programs  opt to make different accounts into a ‘flow - down’ structure, where; 

1 Users have all the permissions of guests,  

 2 Superusers’ have all the permissions of Users, and administrators have full access. 

As we have illustrated thus far in SBD403, this can prove problematic in certain situations.  

This assessment will evaluate your understanding of the separation of specific roles, their  importance, and your implementation of the principles covered in SBD403. The submission  must also include a one-to-two page document outlining the various specifications OR a  design document that details justification for the appropriate architecture.  

This assessment will prepare you for undertaking similar projects in the industry, where you  must understand, follow, and justify your implementation of client and security  requirements. Protection of User (or client) data within industry is of paramount  importance, and can make the difference between success and catastrophic failure of a  project.  

Justification and implementation are the core qualities assessed in this assignment. 

Task Instructions 

Submission for this assignment should be in the form of an executable application that can  be run on the university machines. The language used to develop it is up to you (discuss  with the lecturer prior) but it must have an existing API to read and output to Microsoft  Excel .csv files.  

The User types are as follows: 

Guest: This user is not ‘logged in’ so to speak, and should only have a minimal level of  access. At every available protected instance, the guest should have requested credentials  (such as a username or password dialog that would allow a User to sign in) 

User: This user is ‘logged in’, and can be thought of as a ‘client login’. This user should have  access to their own data, but not access to any other clients’ data.  

Superuser: This user is ‘logged in’, and can be thought of as a staff member. This user can  create new users, add and view data in their accounts, and can also view company-specific  information. They can also view information on their own account, but not other Superusers. They cannot create Superuser accounts.  

Administrator: 

This account level cannot view user information, or create user accounts. However, the  Administrator can view Superuser information, as well as create Superuser accounts. The  Administrator (like the Superuser) can also view the Company information.  

The security types are:  

Public: This information is available to all users. This includes file names, sheet names, and  other miscellaneous data. This also includes access to the tool itself. It should also be public  to create a user account (which then elevates the guest to a user.)  

Client / User: This information is visible to both the specific user and Superusers, but not  guest or administrators. This may include client details - such as names, addresses, and  other private information. Client information should be visible to the specified User and  Superusers only, and not to other Clients.  

Company: This information is visible to users, Superusers, and Administrators. This  information is only relevant to the company. This may include employment information, or  company relevant policies, procedures, and plans.
