$1$ Sample Solution $\backslash$table$[[$Area$,\backslash$table TOPOLOGY

BACKGROUND

The RAO officer at RAO camp and the student at the Marine Engineering Dept. are trying to access the Web Server in the IT Department through the network above.

There are missing technologies, protocols, devices, and connections in the hidden areas $1,2$ and $3.$ Your task is to investigate the possible technologies, protocols, devices, and communication media that should be placed in the missing areas in order to achieve connectivity and security.

Additionally, while choosing the possible media to use, you must consider their effectiveness and cost for the given distances and required data rates.

Moreover, security is very important in the above network, therefore you also need to investigate security threats imposed by the attacker and how to protect the network from those threats.

There can be any devices and communication media hidden inside each area. e$.$g$.$ switches, routers, hubs, access points, UTP cables, optical fiber cables, etc...

Table $1$ below must be used to help students in investigating the optimal network media solution $($in terms of cost vs$.$ performance$)$

TASKS

$1-$ Investigate what technologies, protocols, communication media, and devices should be used in the hidden area $1,$ area $2,$ and area $3$ considering the geographical distances, cost effectiveness, security, and performance efficiency $($minimum data$-$rate required$).$

$2-$ Students are expected to use their proposed devices, technologies, and protocols to achieve connectivity from the RAO officer and the student to the Web server.

$3-$ Students are required to write a report $($with a minimum of $800$ words$),$ containing, as sections, the following: a$-$ Introduction b$-$ Problem statement c$-$ Proposed technologies, protocols, and devices d$-$ Justification of using the proposed technologies, protocols, and devices.

Use a table $($or tables$)$ in this section, a not real example, may not work: Table $1$ Sample Solution

e$-$ Based on table $1,$ what will be the chosen communication media used between all buildings?

f$-$ Justify your answer in point $($e$)$ using numbers $($data$-$rate required vs$.$ cost vs$.$ distance$)$ You must use a table $($tables$)$ based on the previous table $($in point d$)$ in this section, a not real example, may not work $($Please note that costs, maximum length and data$-$rate can be found in table $4$ at the end of this report :

k$-$ Security threats: what are the possible security threats in this scenario, and in your opinion what devices or mechanisms you should use in order to prevent such security threats.

l$-$ Conclusion: you should mention the reasons why a certain device worked or did not work, limitations of certain technologies or devices that did not achieve connectivity, and challenges you may have faced during working with the topology.
