This question involves designing a secure wireless campus network for York St John University,
UK as shown in the *campus map shown. Write a report with the appropriate details (1500 words
max, but flexible). You can assume that a Wired LAN with servers, clients, switches, router and
Internet connection is fully in place in the campus. NOTE: Please answer the questions based on
the marks allocated to it. *The link: https://ift.tt/2AxAcHg
1. You need to analyze the campus plan and the networking scenario well (say, by assuming the
building dimensions, the structure, the number of floors etc). Assumptions on dimensions are
acceptable, as long as they are reasonable. You can use Google map, if needed. HINTS: A table
of buildings with symmetrical dimensions (e.g. Build Name – 100 m x 40 m; with say scale 1
cm = 25 m) and possible area covered can be listed. (5 marks)
2. Your design should cover the campus with as much wireless access as possible with a
reasonable cost. All the buildings should be networked. How do you extend the wireless access
to these 22 buildings? Include the details in your design. HINTS: Discuss your network plan
with possible number of access points and their possible placement. Show the position of
Access Points on the campus map (as a dot and a thin circle around it, with different channels
color coded), showing the radio coverage overlaps (say 15 to 20%). Remember an access point
can cover around 30 to 40 meters well. (10 marks)
3. Draw the detailed network diagram of your recommended solution, with different
views/segments of network connections in different buildings. Come out with a detailed
design solution that is a secure wireless network. Do support your design with reasons and
justifications. HINTS: You need to show the detailed plan of only one floor of any building. In
this figure you can show how the access points are connected to a switch on the LAN (with say
some portion of the network), along with any other installations like Wireless Amplifiers (or
range extenders which has pros and cons), EAP RADIUS authentication server etc. You can
show that for at least 5 buildings, though not all of them. (10 marks)
4. With the design you are proposing, what could be the possible security attacks? Since various
other parking lots can be around these buildings, do you foresee any problems? Come out with
all possible attacks on a wireless network. HINTS: Look into war-driving/parking lot attack
and spoofing attacks. Focus more on attacks on wireless networks (WiFi), and not general
network attacks. Use NetSpot Free edition (https://ift.tt/2mrK3TN) or
Vistumbler (https://ift.tt/1OJfHRW) in the lab or your home to get the screen shot of
wireless access points and comment on what can be seen. Use Microsoft Network Monitor or
Wireshark to capture packets in lab and use screen shots and comments to support your
answer (10 marks).
5. Briefly explain on the countermeasures against the security attacks that you explained in the
previous question. Your design should include such solutions. Justify the use of security
technologies that you propose. HINTS: Briefly explain technologies like WPA, WPA2,
TKIP/CCMP, AES, RADIUS authentication, VPN (for external connection) etc. (5 marks)
6. Show the detailed cost of implementing your wireless solution, in a table format. HINTS:
Research on the costs of access points, switches, antennas, cables, authentication server if any
etc. (5 marks)

7. Show all references used in the report, using appropriate referencing. HINTS: Harvard
referencing can be used and make sure the format is fully followed. (5 marks)
