CYB 200 Module Four Activity Guidelines and Rubric

Overview

In this exercise, you will develop a role-based access control (RBAC) matrix for user access control. RBAC matrices, as a security architecture concept, are a way of represen�ng access

control strategies visually. They help the prac��oner ensure that the access control strategy aligns with the specific access control objec�ves. Matrices also help show when access controls

may conflict with job roles and responsibili�es. When you are comple�ng this type of task, there are a few ques�ons you should always be thinking about:

Who gets to log into the system?

Who gets to view what?

What kind of data are you dealing with (basic data vs. informa�on subject to privacy controls)?

Who gets to add or delete? Who is view-only?

Who should not have permission?

An example of an RBAC matrix can be found in Chapter 6 of your course textbook.

Scenario

You are a security analyst for a healthcare firm assigned to create an RBAC matrix for a new so�ware-as-a-service (SaaS) applica�on for managing pa�ent medical files. There are six

individuals who have roles within the system and need varying levels of access to the medical pa�ent so�ware. Your objec�ves are to set up the RBAC matrix to:

Ensure individuals have access to necessary informa�on for their job role

Maintain pa�ent privacy by adhering to the Fundamental Security Design Principle of least privilege (i.e., business need-to-know)

The following SaaS applica�on parameters need to be determined:

1. Access to pa�ent informa�on

2. Access to employee informa�on

3. Access to the SaaS

4. Access to backup logs

See the User Job Roles and Characteris�cs table below for informa�on on the users, their roles in the organiza�on, and their job descrip�ons.

Prompt

Specifically, you must address the cri�cal elements listed below:

I. RBAC Matrix: Populate the RBAC matrix in the Module Four Ac�vity Template using one or more of the necessary ac�ons (view, create, modify, delete, none).

II. Essen�al Ques�ons: Answer the following short response ques�ons based on your populated table in the template:

A. What changes could be made to user roles through implementa�on of least privilege to be�er support that security design principle? (Hint: Refer to the characteris�cs in the

scenario table above, and consider the characteris�cs that may be contradictory.)

B. What is the importance of this tool to you as a security analyst in managing and protec�ng the environment? Provide an example.

What to Submit

Submit the completed RBAC matrix and short response ques�ons in the Module Four Ac�vity Template. You may also submit this ac�vity in your own Microso� Word document, but your

submission must contain the same elements as the template. Your submission should be 1–2 pages in length (plus a cover page and references, if used) and wri�en in APA format. Use double

spacing, 12-point Times New Roman font, and one-inch margins. The file name should include the course code, assignment number, and your name—for example,
