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.

(c) SECURE IMPLEMENTATION. What are the issues do you think you may MOST LIKELY encounter during the implementation (coding) for this case study? Give examples and suggest how to address them. Please discuss at least two issues.
