COIT20264 Network Design: Cosmos Online Newspaper Project, Term 1 2018

This document presents a comprehensive network design solution tailored for Cosmos Online Newspapers. It includes a logical network diagram, detailed explanations, and justifications for the chosen design, incorporating elements such as routers, firewalls, and wireless cell towers. The design addresses key requirements like integrating an advertisement server, enabling live news reporting via handheld devices, and developing a robust network addressing plan. Security is a paramount concern, with measures including authentication, physical security, data encryption using MD5 hash algorithms, packet filtering, and firewall implementation. The solution also specifies the routing and switching protocols used, such as VLAN configuration, DHCP, access control lists (ACLs), and spanning tree protocol (STP), to ensure efficient and secure network operation. The document assumes the use of Windows Server 2012 r2, server backups, and VPN tunnels for data transfer to enhance security and redundancy.

Assessment Item 1 – Part B
List of Assumptions
The following are the list of assumption made for the development of the network solution for
Cosmos Online newspapers.
 A windows Server 2012 r2 is used as virtual server for hosting the website and it is
configured with proper security mechanism for securing its access.
 The server is backed up for increasing the redundancy and disaster recovery and
uploaded to the cloud server in an encrypted form for increasing the security of the
database.
 There are different sites for the different servers and they are connected to each other via
the internet.

 The storage and the database servers are installed in a demilitarized zone for increasing
the security of the resources.
 A VPN tunnel is used for transferring of the data packets between the different servers
for increasing the security of data communication.
List of Requirements
The followings are the list of requirement that the network solution should meet for the
development of the network solution for Cosmos Online newspapers.
 The network solution needs to integrate the advertisement server with the current
network for streaming live ad contents with the live video feeds provided by the
newspaper publishing company.
 Handheld smartphone devices must be provided to the news reporters for enabling
live news reporting in the areas where there is average internet connectivity
speed.
 Development of a network addressing plan for creating the local area network of
the office and connect the permanent staffs with each other.
 Selection of a top down network topology for connecting the different
communication devices and meeting the requirement of the users.
