Topic: Network Design Report and Presentation Task details: In this assessment, students must demonstrate their understanding of critical thinking in an IT context by examining given problems and proposing solutions using the methods explored in the unit. Students will choose a solution and then implement and evaluate their solution. Students must submit a report that outlines the steps they followed to solve the problems. The approximate word length is up to 1500 words with topology diagrams. The report should be presented with supporting material as appendices, such as the calculations for the IP addressing scheme Practical assignment brief Jackson company is an enterprise Australian company based in Sydney. It is growing fast and the company is aiming to expand their business in other cities in Australia and also in Hongkong. There are 5 sets of user allocations for this scenario: Sydney building (50000 users), Melbourne building (32000 users), Brisbane building (25000 users) and Hongkong building (10000 users) The company uses 15.12.0.0/8 at the company headquarters in Sydney and needs to use a subnetting structure to incorporate the new cities. Adhering to the subnetting scheme and using VLSM, assign a subnet address to the networks and their links. Each branch’s offices have 8 levels of building and access to the Internet is crucial for each office, as well as inter-branch-office networking. Each branch has 6 servers which are located on the Fifth floor of each branch in the server room The large company headquarter is in Sydney and the new subnets must have connectivity from Sydney and other cities in Australia and Hongkong. You need to think about cost-effectiveness also Jackson company is aiming to create an Intranet for its branches in Australia and Hongkong. You need to think about creating a VPN for this company. The company is recently facing DDOS attacks, also Phishing attacks annually and also, they are facing insider attacks. Find some solutions to mitigate these types of attacks. You need to find a solution to mitigate the attacks for their server rooms and also write restrictive policies for mitigating future cyber-attacks and also monitoring insider attacks. Elements Your goal is to design, deploy and successfully implement their business Solution You are required to design the topology for the four new sub-networks and their connection to the Sydney office. You must document each step you have taken, including your research sources. You need to come up with a design report and send it to your technical manager.

Report: The report must contain the following sections:

1. Introduction: Critical analysis of networking requirements
2. Network topology: Discuss the reasons for choosing the particular network topology.
3. Local Area Network (LAN): Design and description of Local Area Network for all subnets, you can use a packet tracer for helping your network design. LAN design connections to the servers, connection to other subnets and also the internet/intranet
4. IP addressing and subnetting for each different city branch.
5. Addressing network security by researching all mitigation techniques and also writing restrictive policies for future attacks.
6. Hardware: Provide a complete description of all interconnecting devices (switches, routers, hubs and access points) and wiring used to build the network. Justify your choice.
7. Conclusion: Comprehensive summary of the work done and recommendations with a lesson learnt
