The purpose of assignment is to assess students on the following Learning
Outcomes:
LO 1 Explain key features of network architecture and purpose of network technologies LO 2 Analyse physical layer for networking, common protocols and multimedia communications
LO 3 Use appropriate network tools and techniques LO 4 Analyse network traffic network security issues LO 5 Apply methods and tools for the configuration, maintenance and troubleshooting of network devices LO 6 Use problem solving techniques to recommend basic network management solutions LO 7 Model the management of a small office network with basic routers and switches
Assignment Description
You are a Network and security engineer for the XYZ Consulting Corporation, which is a
leading network designer and security provider for the small -scale offices. As the Network
and security engineer you are required to perform the following tasks.
Task 1: Propose a network design for small scale office (Ex: Business type, departments,
building plan). You are free to assume the name of the office and number of staffs
➢ Purpose of the Project
➢ Network overview (ex: connecting PCs, subnetworks, servers or wi-fi networks) • Explain briefly about the device used.
➢ Requirements of the project including network diagram
• Draw and explain the proposed network diagram • Design a network using packet tracer. Configure routers, switches and end
devices you have used. Test your network by pinging end devices across different departments.
➢ What are the common attacks plaguing your network? How to prevent from attacking your network?
➢ Critically analyse possible security issues in your network and suggest some prevention
techniques.
Task 2: Use Wireshark to Capture, Filter and Inspect Packets
➢ Install Wireshark and start a sample capture using your wireless interface. Save your
capture file on the desktop with name_studentID.pcap (Example: jack_451245.pcap),
and close Wireshark. Provide a screenshot in your report. (After downloading and installing Wireshark, you can launch it and double-click the name of a network interface
under Capture to start capturing packets on that interface.

➢ Open your name_studentID.pcap capture file in Wireshark and check how many
packets you captured in total?
➢ Which pane displays information about packet details and explain what information’s
are available?
➢ Which pane displays information in the HEX and ASCII form for each packet you've
captured? Explain
Submission Guidelines:
The report should have a consistent, professional, and well-organized appearance.
1. This assessment item requires you to work in a group of 4 students.
2. The word limit of the report is 2500 words.

ID numbers, course details, and the assignment details.
➢ The assignment must use 12-point font size and at least single line spacing with
appropriate section headings.
➢ In-text referencing in IEEE style must be cited in the text of the report and listed
appropriately at the end in a reference list.
4. The report must be submitted in soft (electronic) copy as a Microsoft Word document on the
LMS in Turnitin Dropbox. Assignments submitted on the LMS will only be accepted.
5. Late penalty applies on late submission, 10% per day would be deducted.
6. The assignments will go through Turnitin and plagiarism penalty will be applied.
Marking Guide: 100 Marks
