You are a network security engineer at the UniQoo Design Pty Ltd in Brisbane, Australia. The company  houses more than 500 freelancer designers who often travel to the premise to hold a meeting with  business clients. The designers need to have their creative products available on the Cloud as well as  on their personal laptops so that they can demonstrate their works to their clients.    Recent cyberattacks on Australian companies have heightened the concern for UniQoo Design, as a  number of their competitions reported their ill fate of losing valuable creative assets due to the  cybersecurity attacks.    Your task, as a network security engineer, is to provide convenient Internet access for the  visitors/business partners while maintaining a high level of security for internal staff, including  designers. As the number of internal team is large, a remote authentication server is pivotal to  successful security operations.    In this assignment, your project is to install WLAN for the CBD premise for UniQoo Design. In this  project, you will analyse the threat landscape to check the potential attacks, and design and  implement appropriate wireless network architecture for a secure and convenient business  computing environment. The requirements include; internal data network to provide wired access to  staff members or administrative officers for faster and secure connection to their design data, and  free Internet access for visitors and business clients who are visiting the premise.    Your objective is to fulfil accessibility, connectivity and availability of wireless network with the high  level of security. You need to investigate a set of tools including WAP or WAP2 to provide high level  of wireless security. The details should include technologies in IEEE802.11a/b/g/n and IEEE802.11x  authentication in wireless LANs.     Requirements      For this project, you will design the network as specified in the above scenario from scratch. You  have to submit a group report and specify each individual group member’s contribution on the  front page. You should also address the following tasks in your report:     ● Design of a simple mock business computing network schematics (using Packet Tracer or  other simulator)  ● Discussion of threats in business computing environment (what are the potential attacks to  your business)  ● Wireless network security design using WPA or WPA2 technique with the support of 802.1X    Followed by:  ● Evidence of deployment of wireless network and its security solution using WAP or WAP2 (on  Packet Tracer or other simulation platforms)  ● Segregation of free Internet access network from Internal data network by various levels of  security grouping  o Admin access Prepared by: Tony Jan Moderated by: Dr. Sanjeeb Shrestha March 2021  o Designer access  o Visitor access  Or any other groups you consider appropriate (e.g. marketing team)   Evidence your system has been secured in confidentiality, integrity and availability.    All group members:   Write a report that includes the following sections: abstract, introduction, proposed design, evidence  implementation (on simulator), followed by conclusion and reflection in terms of data ethics.

Abstract
Design and implementation of secure Wireless LAN network for visiting Business Partners and  other guests. The report also highlights the various Cyber threats currently popular among attackers in the region and ways to mitigate and prevent those threats in the new WLAN implementation.
Introduction
History of WLAN
A Wireless Lan is a computer network connected 2 or more computers together without the use of wires. It gives the users the ability to move within a limited area and stay connected to the network. Using a gateway, WLAN can also provide connectivity to the internet.
Wireless LAN or Wifi, as is generally known, was first created by University of Hawaii as a means to communicate between various islands in Hawaii. It was later adopted by IEEE as 802.11 standard in 1997. 
In 1999 Wifi was introduced to the public use as 802.11a and 802.11b standards that were very slow, 54 Mbps and 11 Mbps respectively.. But since Wifi was an optional standard in most systems and there were no smartphones then, this standard was enough.
By 2003, these speeds were not acceptable and thus came 802.11g, that provided speeds upto 54 Mbps and later in 2007 came the 802.11n standard that provided speeds upto 450 Mbps.
With the advent of 802.11ac, Wifi has reached the speeds in gigabit.
Network Components
Access Points: These are the base stations for the wireless networks. They emit and receive radio waves that are used by Wireless-enabled devices to communicate with. The access points communicate to other access points using the physical layer, then it is called Basic Service Set (BSS).
Clients: Any machine that connects to a Wireless LAN but do not itself act as an Access Point, are known as wireless client. Wireless clients can be both movable and immovable. In adhoc Networks, there are no access points and thus do not connect to any basic service set.
Repeater: A repeater is a Wifi range extender, that do not create a new Wifi network, but simply extends the range of the existing Wifi coverage. This is generally done by putting the repeater in one Wifi Channel for receiving and making it transmit its own signals in a distinct separated Wifi-Channel to avoid interference.
Channel: Channels in Wifi are distinct bands of frequescy in the Wifi range that is used by the transmitting wifi device to send its signals in. There are separate channels in wifi to prevent frequency interference between wireless signals from various wifi devices placed near each other.
Outline of report
Uniqoo Designs Pvt Limited has about 500 designers working both on-premise and away intermittently. The company needs a secure way to allow its designers to access their designs on the cloud from both locations. Also avoiding any unauthorised access to those files from anywhere else. Uniqoo requires to implement security measures such that no unauthorized person can access the WiFi network as there has been cases of security breaches in the industry earlier with competitors and other Australian companies.
