Practical exercises assess students’ ability to apply theoretical learning to practical, real-world situations on a weekly basis. The practical exercises will improve student’s ability to practice information security using Linux/Kali Linux platform such as phishing attacks, encryption and steganography and other functions.
Students will be required to complete the practical exercises during the workshop and therefore, attendance is required as part of this assessment. Students will not be assessed on work that is not produced in the workshop, so attendance is required as part of this assessment. Students are required to submit the work that they have completed during the workshop session only. The details of the lab work and requirements are provided on the online learning system.

Assessment Objective
• This assessment enables you to comprehend the fundamental concept of network design and acquire the skills necessary to develop both logical and physical network designs. • The simulation of a Local Area Network (LAN) using Packet Tracer enables you to comprehend the network architecture and acquire the necessary skills to successfully set up a LAN.
Assessment Details:
ABC is a global IT company which mainly based in USA. Recently, the company has decided to move to the Australian market. ABC has decided to establish two main branches (Brisbane and Sydney) with three networks as follows:
• Brisbane (in a two-story structure):
o NET-A: 10.10.1XY.0/24, will have up to 300 employees.
• Sydney (in a three-story structure):
o NET-B: 172.16.1XY.0/24, will have up to 200 employees,
o NET-C: 192.168.1XY.0/24 will have up to 400 employees.
Every department has its own server. It is recognised that employees should be able to communicate with and access data from various servers within the two locations. You are tasked to design a network (LAN) for the Sydney branch (enterprise campus). The Sydney branch will be connected to the Brisbane branch. Consequently, you need to incorporate WAN access into the design of the LAN for the two branches.
The network will contain a data centre as well as an e-commerce edge. In addition, employees will bring their own mobile devices to work (e.g., laptops, smartphones, tablets). Wireless communication facilities (Wi-Fi access sites) will be used by employees to access necessary information such as their work email, required documents, and the Internet.
Requirements
You have been recruited as an IT Administrator in the IT department and tasked with analysing, designing, configuring, and simulating the new network for the Brisbane and Sydney branches.
There are two parts of the requirements for this assignment, network design and network simulation.
a) Network Design Tasks [30 marks]
Task 1
Develop a logical design of the Sydney network branch using the building-block network design process. Consider the anticipated expansion of NDC. You need to consider the following elements for the logical design:
• Network architecture components.
• Application systems.
• Network users.
• Categorizing network needs
Task 2
Design the network’s physical architecture based on the logical architecture completed in Task 1. Note that you are not required to alternative design. Regarding the physical construction, you need to consider the following:
• Designing client and servers
• Designing circuits
• Network design tools
Note: The following drawing tools can be used to create both logical and physical layouts. • Concept Draw or
• SmartDraw
• Lucidchart
• Cisco Packet Tracer or any other network design software to draw the layout of logical and physical network designs.
Task3
Briefly describe how you will minimise interference from Wi-Fi access points (APs) on separate floors.
b) Simulation [70 marks]
You have been asked to use the Packet Tracer, as shown in Figure 1, for the simulation task. Simulate and test the configuration using the ping command for both Local delivery (devices within the same network) and remote delivery (devices within separate networks, such as Brisbane and Sydney).
You can use the Lecture notes or VLSM to subnet the networks.
Prepare a report to provide the details configuration for the network for ABC company.
In this task, you will complete the required information using the IP network diagram shown in Figure 1. To optimise your grade in this section, address the following points:
• List all assumptions and their explanation.
• Display each calculation for the number of subnets, IP addresses, valid hosts, gateways, and subnet mask for Tables 1, 2, 3, and 4.

Assessment submission
Your report must include a cover page that includes the student’s name and student ID. You need to submit the design document as outlined above with a working Packet Tracer file. DO NOT ZIP THE SUBMISSION FILES.
For successful completion of this assessment, you are required to study the material provided (lecture slides, tutorials, and extra reading materials), engage in the unit’s activities, and in the discussion forums. The prescribed textbook is the main reference along with the recommended reading material. Students are expected to discuss their work with the lecturer and to seek support. In completing this assessment successfully, you will be able to develop networking skills including design, configuration and testing of a computer network using a simulator. This assessment helps in achieving ULO-2.
Marking Criteria and Rubric: The assessment will be marked out of 100 and will be weighted 40% of the total unit mark.

Assessment Details:
Your team has recently been hired by a car industry company that employs various types of robotic systems for tasks ranging from assembly, welding, and painting to inspection. Internet of Things (IoT) devices are utilized to control the robotic systems both locally and remotely.
In recent years, there has been a growing focus on the risks associated with the use of simple IoT devices in services that have access to sensitive information or critical controls. To enhance the resilience of commercial IoT devices against cyber-attacks, security considerations should be integrated right from the design stage of new products. However, the wide heterogeneity of IoT devices poses challenges to the development of well-established security-by-design methods for the IoT. Choose one of the following IoT devices:
• Arduino
• Raspberry PI
• BeagleBone
• ESP32 and ESP8266
For the type of IoT device your group has selected, you will need to discuss the following:
1. Identify and discuss three security vulnerabilities specific to the selected IoT device. 2. Demonstrate the working mechanism of two types of attacks against the selected IoT device. 3. Demonstrate two techniques or security tools that can be used to mitigate/prevent the identified attacks in point (2).
4. The objective of computer security is to protect the Integrity, Confidentiality, and Availability (CIA) of information on the devices that store, manipulate, and transmit the information. Analyze the attack methods identified in point 2 and the security tools identified in point 3 against CIA.
5. Demonstrate the main challenges in protecting the selected IoT device.
The importance of cryptography has increased over time, making it a key defense in securing data from threat actors. Select one type of cryptographic algorithm that has been developed or proposed for the selected IoT device and provide its working techniques and features.
In your report, you have to support your discussion with references from recent conferences and articles published within the last 4 years that are related to the selected IoT device.
In completing this assessment successfully, you will be able to investigate IS security, risk threats and propose the suitable security controls, which will help in achieving ULO-3, and ULO-4.
Marking Information: The applied project will be marked out of 100 and will be weighted 30% of the total unit mark.
