WIRELESS NETWORKS AND SECURITY
Introduction
The report is developed for designing and implementation of a secure wireless enterprise
wireless network for an organization. The network solution is developed after a detailed analysis on
the current technology that can be applied for maintaining the confidentiality of the organization.
The settings that should be made on the networking device should be analysed for securing the
network from the unknown sources. The main areas that should be covered for the enterprise is
demonstrated using the network design created for the enterprise. For maintaining the security of
the network the server is configured with AES encryption protocol and authorization, authentication,
integrity and network intrusion is prevented for the management of the network. The security of the
wireless network is the main factor for the success of the network and for enabling remote
connection the RADIUS server should be configured with the appropriate settings.
Exploring ethical implications
The confidential information of the enterprise should be kept secured and the wireless local
area network should be secured with the application of encryption algorithm such as WPA2 for
improvement of the security of the organization. An analysis is made on the ethical implication for
the installation of the network device in different location of the workplace area and documented in
the report. A design of the enterprise wireless network is also given in the report for the
identification of the network topology used for the development of the network. For the analysis of
the network a social analysis is done and the users are involved in the analysis for the identification
of the needs of the wireless framework. The proposed action that is taken for designing the network
should be evaluated for finding its consequences for deployment of the network device in different
location of the network. The radiations emitted from the network device and the standards
maintained for deployment of the new device should be analysed for the management of the
network and removal of the constraint to develop the network framework. For testing the network a
penetration testing should be used and it can cause violation of the trust issues of the organization.
The details of the testing team should be documented for the management of the network
information and maintaining the confidentiality of the data. The different acts such as computer
misuse act 1990, data protection act 1998 should be evaluated for the protection of the data and
policy of the organisation. The router configuration used for connecting the different departments of
the organization and securing the wireless network should be kept protected and the computer
misuse act helps in implementation of a legislative control on the network for reducing the frauds
and illegal access of the network. The application of the act causes the unauthorised access of the
network to be considered as criminal activity.

Design of secure enterprise wireless network
The wireless network is designed using three cisco 2811 series router and each of the router
are connected with each other for increasing the redundancy in the path for sending and receiving
the data packets in the network. The router 1 is connected with two local servers that are used for
storing the information of the organization and management of the information system. The Router
2 is connected with a switch for the management of the local distribution and connecting the
different hosts in the network. The wireless access point is also connected with the distribution
switch. Two different vlans are created for connecting the wireless hosts and the pcs and increase
the security of the network. The wireless access points are configured with the application of
security encryption for restricting the unknown users to connect with the wireless network of the
organization and keep the network secure from illegal agents. The routers are interconnected with
each other suing serial connection such that the connection is stable and The two access point
deployed in the network are kept in the same VLAN. The Router 3 is also connected with a switch for
the management of the distribution of the network. An analysis should be made on the number of
users and the area of coverage of the wireless network for the installation of the access point in
different location of the network. For enabling the VPN and the remote connection with the user the
server 2 is configured as a RADIUS server and username and password is set for the management of
the remote users. The password management is important for the maintaining the identity of the
user and record the details of the user for allowing them to access the sensitive information of the
enterprise network solution. The router 1 should also be configured with IPSEC protocol and
Windows server 2012 R2 should be used as a RADIUS server configuration with the management of
the authentication service and configuring the active directory service. The router should also be
configured with the firewall policy such that the unknown IP address and the data packets can be

blocked to reach the server. The channel used for the transmission of the VPN traffic is also
encrypted for the increasing the security of the network framework.
Analysis of secure enterprise wireless network
a. Authorization
The user should be authorised for accessing the wireless network and the configuration
choices should be given to the user such that the records of the user using the wireless network is
kept. The user should be managed with controlling the encryption and development of a user access
policy for the personal and corporate device provided to the employees. A user access policy should
be created and the use of third party tools for the automation of the client provisioning and
integration of the wireless access control with the other network access control. The guests
connecting to the wireless network should be redirected to a page accepting the user access policy
for securing the company equipment. The creation of the VLAN and running antivirus program can
help in controlling the wireless network device. The embedded wireless device on the WLAN can be
managed with the use of pre shared WPA 2 and AES encryption.
b. Authentication
Different types of authentication techniques such as open system authentication, MAC
based access control can be implemented for allowing the network device to connect with the
wireless network solution. The open mode is used when guests are needed to connect with the
wireless network for increasing the efficiency of the work and management of the network
resources according to the business policy of the organization. The Mac based access control is used
for a closed network where the registered device can only connect with the wireless network for
sending and receiving the data packets. The Pre shared keys can also be an alternate solution for the
authentication of the user using the wireless network where the pass key is provided to the user to
connect with the WLAN and the strong encryption is used for the management of the authentication
of the user.
c. Integrity
The integration of the mobile information is essential for eliminating the limitation of the
business boundaries and enforcing the security priorities from the perimeter of the network. For
maintaining the integrity of the corporate information focus should be given on the prevention of
unauthorised access and maintaining a control on the wireless network environment. With the rapid
growth in the adoption of the wireless network the implementation of network firewall, enforcing

WIRELESS NETWORKS AND SECURITY
the security policy has become an important task for the prevention of the malicious attempt on the
network.
d. Network eavesdropping prevention
For the prevention of the network eavesdropping the wireless access point should be
configured with WPA2 encryption because it provides better encryption than its primitive versions. It
should also be analysed that if the router supports partitioning and layer 2 isolation can be applied
for blocking the user to user communication and make the network secure from the internal users.
For sharing of the file and the information the user needs to communicate with the RADIUS server
and it needs complex configuration for connecting with the wireless network.
Implementation of secure enterprise wireless network
For the implementation of the secure enterprise wireless network it is important to analyse
the different wireless standards and analyse the encryption methodology that can be selected for
the development of the wireless network framework. The risk associated with the development of
thee wireless network framework is analysed for the development of the WLAN network. The
intruder can access the wireless network from remote location and use amplified equipment for
breaking the wireless signals and gain the access of the framework. A proper planning should be
made for defending the network from the external agents. A proper planning for the management of
the configuration is essential for eliminating the risks and taking the necessary steps for protecting
the network for the migration of the risks. There should be a classification of the data into private
and public data for minimizing the bleeding of the control signals. Uni-directional antenna should be
used for localizing the signal and shielding it from the external walls for expectation of the location.
Each of the layers of the OSI model should be used for protecting the wireless network signal. There
are different tools that are used for the penetration into the network and kali linux is the mostly
used tool that are used for gaining the action of the network. With the growth of the wireless
network IEEE 802.11 are widely used for the management of the media access control and it is
important for the application of the encryption protocol for securing the access points.
The defence in depth technique is implemented with the application of WPA2 and enabling
wireless intrusion detection system. An active scanning and monitoring of the unknown device also
helps in prioritizing the deployment of the wireless network. There can be different types of attacks
such as active, passive, inside, close in and distribution attacks. The link and network layer
encryption can act as the first defence and security encryption can also be used for increasing the
security. The defence mechanism for the active attack is to defend against the enclave boundary and
defend from the computing environment. The insider content can also be protected with the

6
WIRELESS NETWORKS AND SECURITY
application of personnel and physical security and auditing, authentication of the access The close in
attacks can also be avoided with the application of physical and personnel security and using
countermeasure for technical surveillance. The attacks in the distribution layer can be avoided with
the use of trusted software and the use of run time integrity controls.
Conclusion
The secure enterprise wireless network solution is designed in Boson network for the
identification of the new concept and technology used for the development of the network. For
designing the network an analysis is made on the different available network device that can be used
for serving the needs of the users using the enterprise network. Two network servers are used and
configured according to the different service that are needed for providing authorization,
authentication, integrity and prevention of the eavesdropping. An intrusion prevention system and
an intrusion detection system is used for gathering evidence from the network and use it for
securing the network. The combination of the password encryption protocol should use with the
combination of alpha numeric and special character for increasing the security. The distribution layer
switches are configured with VLAN for isolating the access point maintaining the stability of the
WLAN. The default security mechanism can be altered and added with new security techniques for
getting the best security solution. The application of WPA2 for increasing the security of data can
help in enforcing the centralized security policy and enforcement of the wireless security policy for
the access point. The effect on the ongoing traffic is analysed for identification of the impact of the
application of the wireless security policy and reduce the error for getting the best possible output
from the security policy designed for the WLAN of the enterprise.
