Introduction
The wireless networks are among the major problems in the computing and information
technology that are susceptible to several security threats as well as attacks (Liang & Yu, 2015).
The areas of the wireless network usually involves the transfer of the information hence needs
security in order to ensure that organization information has not been breached. Wireless
networks could be secured via different means which are discussed in this report.
Overview of the technology involved
The wireless technology in their simplest perception allows one or perhaps more devices to
connect without the physical connections and would not require the network or perhaps the
peripheral cabling (Liang & Yu, 2015). The wireless technologies utilize the radio frequency
transmission as their means for the transferring of the data, whilst the wired technologies utilize
the cables. The wireless technology for the majority of the cases ranges from the intricate
systems for example the Wireless Local Area Networks (WLAN), the cell phones to the simple
devices for instance the wireless headphones, microphones and other devices in particular the
remote controls, or perhaps the store information. Additionally, they might also consist of the
isolated controls, some cordless computer keyboards and mice and wireless hi-fi stereo
headphones.
Relevant technologies and applications of those technologies
In undertaking research on the wireless security and preventive methods, the scope of the area
network technology were used (Stallings, 2016). The numerous tools were employed locally in
the coverage. These types of tools include the switches, computers and network. Other tools that
are employed for the communication within the local network were also considered (Liang &
Yu, 2015). Without any doubt, the wireless technology has been relevant and a vital component

INFORMATION SECURITY 4
when it comes to the computer and the telecommunication world along with the Wireless third
generation network which offers an increase in the benefits to various networks. The WLAN
and the wireless technologies are the ones which have been identified to have great potential to
the value of the custome r(Pierson & DeHaan, 2015). 3G is regarded as the standard which
defines the technology which could provide the bandwidth wireless access over the large area as
well as support to different services for example the WLAN, and roaming which is the disruptive
technology which offers a much higher bandwidth within the smallest areas.
The wireless security technologies are Wi-Fi Protected Access, WiFi-Protected Access 2 and
Virtual private networking (Pierson & DeHaan, 2015). The WPA and WPA 2 are essentially the
based security certification from the Wi-Fi alliance for an organization, SMB as well as the small
office Wireless LANs which offers a mutual authentication to verify on the personal users as
well as the advanced encryption (Pierson & DeHaan, 2015). WPA usually offers an organization
class encryption as well as WPA 2. It has been recommended that the WPA or the WPA 2 be
utilized for the enterprise as well as the SMB wireless LAN deployments (Pierson & DeHaan ,
2015 ) . WPA and WPA2 provide protected access control, a powerful data encryption and also
simultaneously protecting of the network from any specific the active attacks. On the VPN
provides an effective security to the customers’ wirelessly accessing network during the road and
off from the office (Pierson & DeHaan, 2015). Utilizing the VPN the customers might make a
secure tunnel between 2 or more points on the networks using encryption, although the encrypted
data has been transmitted over the unsecured networks for instance the public internet.
Highlighting the challenges/problems in your chosen research area

INFORMATION SECURITY 5
There are different security issues which have affected the wireless networks over the last few
years Stallings, 2016). It is known that an individual without comprehension of the networks can
easily establish a flawed and vulnerable network. For that reason, it is very important remember
that even their system administrators might lack understanding to the wireless network
implementations (Stallings, 2016). Currently there are various security challenges which affect
the wireless networks these are highlighted as follows;
DDoS attack
In the DDoS attacks, a hacker set up an application on the machine which afterwards along with
the other wireless networking systems might be called to take part in the attack (Stallings, 2016).
Considering that the DDoS attacks normally provide heavier volume of the messages they have
got the prospective to be much disruptive compared to simple DoS attacks that could derive from
one particular computer (Stallings, 2016). In any given attack it might develop on the veritable
army of the zombie systems that are accustomed to launch the attacks at will.
Rogue access point
This is essentially an accessibility point that is included with a network without one
understanding. A person does not need the knowledge that it is there. This is an access point
which could generate some huge security issues. One is due given it could be simple to plug in
the wireless gain access to point in it. In case one does not do any type of the network access
control protocol on ones coverage, it might turn out to be easy for the additional workstations
and gain access to reveal be incorporated with a network.
Jamming

INFORMATION SECURITY 6
The wireless interference translates to disruption of one’s network. This really is an
exceptionally significant problem particularly owing the fact that the wireless signals could
possibly be disrupted. This kind of the disturbance might be established by utilization of a
Bluetooth headset, a microwave or perhaps a cordless phone. This might generate the
transmission and receiving of the wireless networks to be a challenge.
Evil twin
A wireless evil twin usually comes into the play whenever the criminals are trying to generate a
rogue access points to be able to gain a having access to the network or simply access to the
information employed via the network. Determining the evil twin can be quite easy given that all
one demands would be to obtain a wireless access point, connect it into the network after which
configure it exactly as the current existing network . This is feasible when it comes to the open
access point which does not have any kind of passwords which are associated to them.
Packet sniffing
When the data has been sent back and forth over the coverage, it is sent out to the packet. Given
that the wireless traffic is dispatched over the air, it would be simple to capture. One can find
plenty of the traffic which is sent over the air which means there is certainly absolutely no
encryption and the files are in the plain text for virtually any person to check out. There is plenty
of the traffic which is sent in the clear meaning there is certainly simply no encryption and files
are in the plain text for any individual to read. Utilizing a tool for example the Wireshark allows
somebody to read the data transfers in the plan text. This might lead to stolen passwords or
leakages of the sensitive information much conveniently. The data which is encrypted may be
captured.

INFORMATION SECURITY 7
Preventive techniques
There are many preventive techniques which are utilized to prevent the hacker from the access of
wireless network these approaches are as follows;
Usage of encryption to wireless network
When a person goes remote, it is important to scramble the data you are sending to the remote
system, to enable the hackers not access to the data. The use of encryption helps to scramble the
data which is sent into the code which prevents others from opening it. The use of the encryption
is the ideal technique to secure the system from the hackers. The two most types of encryption
technologies are Wi-Fi Equivalent Privacy and the Wi-Fi Protected Access. WPA2 is easily the
most technology which is secured and its utilization is applied on uncommon chances whenever
that decision is reached. The encryption algorithm for most of the time shields the network
against the standard software engineers (Liang & Yu, 2015). The WEP encryption algorithm just
happens to be working in certain seasoned switches, wherein there is certainly absolutely no
shielding against particular programs from the hackers. Access should be only permitted to
certain gadgets in order to gain access to the remote system. Each device which speaks with the
method is a Media Access Control. The isolated system generally allows specific gadgets with a
particular MAC location to get access to the system.
Securing of router
It is essential to protect system from attackers, over the internet by preserving the switch
protected. The switch is able to coordinate on the activity between nearby application and the
web. This is the first step to safeguard against any attack. In the event that the switches are not
secure, hackers can access the delicate data from the gadget and they are able to seize the control

INFORMATION SECURITY 8
of the switch and direct the network to the deceitful sites. There is need to change the switch
name from the default one. Following the advancement in the technology, it is important to
ensure security to the switches through periodic updates.
Picking a reliable and exceptional secret word for remote system
The remote switch generally comes preset with the default secret key. Whenever setting an
excellent secret key for the remote system, it is very important to make sure that it is certainly
not less than twenty figures in length and it includes numbers, letters and distinct images
(Stallings, 2016). With this setting it could keep other individuals from getting to the system.
Steganography
When it comes to cryptography it protects the messages from being captured by parties which
are unauthorized (Stallings, 2016). This technique enables concealment of the message which is
sent and if it is certainly not discovered it makes the sender and receiver invisible. The use of the
technique provides security and at the same times some anonymity. All the information hiding
techniques which could be used to exchange the steganogram in the telecommunication network
is described by the use of this technique (Wright & Cache, 2015). The network steganography
usually uses the communication protocol to control the elements as well as their intrinsic
functionality.
