Recently you have been hired as a programmer in a cloud-based company. There are ten members in your team. Your team is assigned to build a secure Learning Management System (LMS). The system should have the following requirements.

• User registration (after successful registration with username and password, the program will show a successful message, otherwise it will show a warning message for one failure attempt).
• User login (a user can be a lecturer, student, or administrative staff, who can log in from anywhere).
• Modify learning materials (a lecturer can add and modify learning materials).
• Create discussion (both lecturer and student can create discussion topics).
• View learning materials (all participants can view learning materials).

In addition to the above-mentioned requirements, you should consider and take care of the security measures such as input validations (e.g., username should not be more than 50 characters, only alphabets and blank space can take as input), buffer overflows, etc. that are relevant to the LMS system.

Now do the following tasks based on the information above.

(b) SECURE DESIGN. List the use cases and misuse cases of the system. Draw a flowchart to illustrate the software design. Reasonable assumptions can be made.

(d) SECURE TESTING. Write the test script to test both the functional and security requirement of the feature view and answer discussion questions. Reasonable assumptions can be made.
