Network Design for Data Security

This assignment delves into the crucial topic of network design with a specific focus on bolstering data security. It examines diverse network design patterns, including those tailored for data-intensive science applications (Science DMZ). The analysis encompasses cybersecurity-aware network designs within industrial control systems and explores optimization techniques used in sustainable supply chain network design. Furthermore, the document investigates the role of routing protocols like OSPF in enhancing wireless ad hoc multi-access networks. It also considers cryptographic principles and practices essential for securing communications in a network environment.

1. Introduction
The network is design for Victoria University and detailed design of the Ethernet for its
five story building is given in the report. The LAN is sub divided into different parts and the
prototype of the network is deigned in cisco packet traces and attached with the report. Different
subnet and IP address is used for different parts of the network according to the requirement of
the university. The computers connected in the office are assigned same IP address and the Lab
network is designed with different IP address.
The design of the network is proposed detailed function of the network is shown in the
report that would help to improve the productivity of the university and help to communicate
with the departments easily. A sitemap is created for the network for demonstration of the
location of the device that is installed in the network. The list of the network address that is used
for the configuration of the network devices are given in the network. The network is configured
and the configuration are given in the configuration document and the screen shot of the
simulation are attached for increasing the efficiency of the network.

4. IP network addressing plan
Variable length subnet mask is used for the preparation of the addressing plan and some
extra IP address are reserved for each of the subnets for supporting the growth of the university
network solution.

7. Conclusion
The main requirement of the network is to configure the network in a simulator according
to the business rules of the university. The configuration if the network is done in cisco packet
tracer and the functionality and connectivity of the nodes are tested for the development of a
simplified LAN solution for the network. The gateway interface of the router is pinged for
testing the connectivity of the network. The device used for designing the network should have a
proper IP address and a proper addressing plan is created for accommodate the future growth of
the university.
