Introduction to Computer Security – G6077
Weighting: 50% of marks for the module
Version Information: Oct 2024
Submission deadline: Check deadline on Sussex direct. e-submission to Canvas
You must work on this assignment on your own. The standard Informatics rules for collusion, plagiarism and lateness apply. Any cases of potential misconduct discovered will be reported and investigated.
Part A – Virtual Private Cloud (10 marks)
Use the AWS services to implement the infrastructure given below. Once you implement this, you will need to take screen shots of your settings to provide it in the report.
Part B (** marks)
Lovejoy’s Antique Evaluation Web Application
In this part of the coursework, you will develop a secure web application for a local antique dealer named Lovejoy. Lovejoy wants a minimum viable product allowing customers to register and then request evaluations of potential antique objects. Lovejoy has many rivals in the antique business who may sometimes resort to underhand tactics and so is very concerned about the security of the application.
Your secure web application will need to have these features for the minimum viable product (MVP) release: user registration and login, a password policy, “request evaluation” page and then an extension of the “request evaluation” page file upload to allow upload of photos. Finally, Lovejoy needs a request listing page.
You should build Lovejoy’s MVP focusing on the following features in each task. Mark allocation for each task are as described below and in the security analysis grid. You should reflect upon your work and provide estimates of how much you’ve achieved by filling out the marking grid. An example of self-reflection is provided in the Canvas. There are thus 30 marks for completing the application reasonably, 50 marks for the security features identified and implemented, and 10 marks for self-reflection and video quality.
You have a choice of technologies from which to build the application:
PHP
Java
Python
No other approach is allowed. If you are using Java and Python, you should research it yourself to find out where you want to host it.
Task 1 - Develop a secure web form that allows customers to register in the application. They must register an email address, password, name and contact telephone number. The users’ details should be stored in a database.
Code Quality 5 marks
Database Design 5 marks
Task 2 - Develop a secure login feature.
Code Quality 5 marks
Task 3 – Extend the password management feature to provide password strength recommendations and password recovery.
Code Quality 5 marks
Task 4 - Implement a “Request Evaluation” web page only accessible to logged in users. This web page should have a comment box to type in the details of the object and their request, and a dropdown box for preferred method of contact between phone or email. The evaluation page should allow for file upload of a photo of the object.
Code Quality 5 marks
Task 5 – Implement a page that displays a list of evaluation requests. This page should only be visible to an administrator role. Code Quality 5 marks
Submission guidance
You are only submitting the report to the Canvas. You must follow the report template.
Report -- You must use the report template provided at the end of this coursework description. In your report, you will provide screenshots of all the marking criteria elements and annotate where necessary. In screen shots for the code, please don’t give a big chunk of code, provide only the related lines. Use bullet points to give any explanation, please don’t write big paragraphs.
Recording -- You will use Sussex Panopto to record a video to show the working of your application and its security features. Useful links provided at the end about Panopto. It is a very straightforward tool to use. You log in using University credential, select the right screen, and record the application to show different features. Show us the aspects that cover marking criteria. Consider the following when recording.
1) Recording must not be more than 10 minutes.
2) Must show the testing of all tasks in sequence (features) and its security features
3) Provide voice over or textual application on the video to explain the recording.
4) Record screen and yourself in the video.
5) Use the self-reflection grid in the task 0 to show the order of recording features.
When you record the video, from the settings, there is a share link button, click on it and select the option that anyone at our organisation who has the link can access the video. Copy that link and put it in your report.
How to use Panopto?
Recording presentation using Panopto
More guidance about recording the video will be provided in the Canvas.
Code file location (OneDrive)-- Upload your code to the OneDrive and provide the code link in the report for our inspection.
Select the folder where you have all the code, then click on the share option. In the settings, click on the pencil drop down menu and select the option can edit. Copy the link and put it in your report.
See the recording on the Canvas how to setup this in a correct way.

Excellent (15-13) Good (12-10) Average (9-5) Poor (4-0) 15 marks
Policy has no flaw, and its implementation is excellent. Various mechanisms implemented to ensure password policy is secure. Policy has no flaws, but implementation of policy is simple. Password policy has very few flaws. However, different sections of policy are implemented and working. Policy has many flaws for example password is not encrypted, and no salt applied. Password forgot policy has security flaws. Password policy 15marks
Password entropy, encrypted storage, security questions and recovery of password
Several countermeasures are implemented, and the quality of countermeasures are excellent. Countermeasures are implemented in all the pages however quality of implementation is simple. Implemented countermeasures only in some parts of the application.
Very little effort to implement countermeasures to avoid these vulnerabilities.
Vulnerabilities 15 marks
SQL injection, XSS, CSRF, File Upload and any other obvious vulnerability.
All the requirements are implemented to authenticate users. Implementation quality is excellent. All requirements are implemented to authenticate the user. However, quality of implementation is simple. Only some obvious requirements are not implemented. Lots of obvious authentication’s requirements are not implemented. Authentication and Encryption 10 marks
User identity management (registration and login etc), Email verification for registration, 2 factor authentications (PIN and or email)
Encryption applied reasonably to secure assets
Excellent implementation of countermeasures against these attacks. No flaws in countermeasures however quality of implementation is simple. Some flaws in countermeasures Very little effort against these attacks. Obfuscation/Common attacks 10 marks
