Assignment Description

Enterprise wireless LAN deployments have skyrocketed in recent years, evolving from guest access in
conference rooms, to limited hot zones of connectivity within the enterprise to full coverage throughout the
organization. Unfortunately, many of these deployments are still insecure, leaving opportunities for the just
plain curious or malicious hackers to try and access confidential enterprise information. Securing a wireless
LAN is not hard – industry advances in technology and vendor innovation makes this easier than ever.

Default settings for most access points do not include any form of security being enabled. This is the most
common reason that wireless LANs are hacked or used by unauthorized personnel. When deployed,
immediately turn a method of over-the-air security on.

For enterprises, it is recommended that the most secure over-the-air encryption and authentication method
e used – either IEEE 802.11i or a VPN. IEEE 802.11i, also known as WPA2 when the access point is certified
y the Wi-Fi Alliance, uses IEEE 802.1x for mutual authentication between the client and the network and AES
for data encryption.

Its predecessor was WPA, an interim form of security certified by the Wi-Fi Alliance while the 802.11i standard
was still being ratified. WPA also uses 802.1x for authentication, but TKIP for encryption. While AES is
considered the stronger encryption method, it is worth noting that WPA has never been cracked. 802.11i,
WPA2 and WPA require the use of a RADIUS server to provide the unique, rotating encryption keys to each
client.

This assignment requires the students to design and implement a secure enterprise wireless network,
considering the ethical implications. The students are required to complete the following tasks and submit a
eport on Moodle.

1. Explore the ethical implications in the design and implementation of a secure enterprise wireless
network.

2. Design a secure enterprise wireless network, employing Boson Netsim.


3. Analysis of a secure enterprise wireless network using WPA2 and the RADIUS server, considering the
following aspects:

a. Authorization
. Authentication
c. Integrity
d. Network eavesdropping prevention


4. Implementation of a secure enterprise wireless network using WPA2 and the RADIUS server.

5. Demonstration in Week 11 during the Lab.

The tutor will assign the groups, maximum number of students in a group is 3 and the students in each group
should be from the same lab.

1. Introduction
The fast acceptance of wireless networks in different modern enterprises involves the network security as the major dimension against the vulnerabilities caused by different intruders and hackers. The use of handhelds increases the development of wireless networks for different applications and their required data. As the extension of some wired network, wireless network provides improvements and better response to its customers from bottom line. The security of wireless network is considered by deployed security policy, deployed security to network, security to Ethernet, security from outside threats, and educating users with respect to wireless policy. So, development and maintaining the security of wireless network is most critical task for a network administrator in modern enterprises [Wright, 2015].
2. Ethical implications of secured wireless network for any organization
The development of proper security related to wireless network is considered as the most important aspect in modern enterprises. The implementation of wireless network in any enterprise has certain possible legal as well ethical implications for network administrator and end user. For developing the wireless network for any enterprise, 802.11x standard developed by IEEE is being mostly used. In these networks, client machines use the AP (Access points) to make their connectivity with developed network. The AP of any wireless network provides central services to end users. The BSS (Basic Service Set) is being used by these AP’s for communication services. The client machines can over pass these BSS, and can use IBSS for making independent and peer based direct connections. This is not ethical that client overpass the developed AP of any wireless network.
Thus, the development of wireless network has associated ethical security implications which require considerations for end users. The points showing such ethical implications of secured wireless network for any enterprise are listed below:
1. The maintenance of confidentiality is the main ethical implication in wireless network. The end user of wireless network is responsible to maintain the confidentiality of network credentials [Rodríguez, 2015].
2. The following of developed WEP (Wireless Equipment Privacy) by end user is also an ethical implication towards network.
3. There are nea
y 16 million different initialization vectors are being used in 32 bit IPv4. In any wireless network, so many different data packets are travelling at the same time. Any hacker can make a watch on repeated data packets based on the vector length. So, it is ethical duty of end user, not to make transfer of data packets of same size continuously on used wireless network.
4. The encryption of RC4 is mostly used in development of wireless networks. The RC4 is a mathematical algorithm, so, hackers can use this RC4 for finding the WEP key. So, it is ethical duty of network administrator to make regular updating and required changes in developed WEP key.
5. The WEP developed for any wireless network has no management of key for improved security of wireless network. It is a time consuming process to change the keys for developed AP’s and connected clients of any wireless network. But is an ethical duty of network administrator to make regular changes and different keys for each user.
6. The developed AP’s of wireless network can be hacked by intruders which may cause network jamming, DOS attack and SYN flood. So, maintaining availability of wireless network under these attacks is big challenge for network administrator. The use of...
