ABSTRACT
Wireless networks are mostly common and are the
part of every organisation or an individual. In this
article we look into the technology of wireless
network and security features of WLANs, delinquent
and attacks in IEEE 802.11 WLANs. There are
variety of attack methods that can be used against the
uses of wireless networks. Modern wireless data
network use a variety of techniques to provide
obstacles to such attacks. This article also discuss the
risks of wireless security in an enterprise. We
conclude that combined effort of users, employers and
system administrator is required to fight against such
malevolent activities.

INTRODUCTION
Wireless networks became part of every
organisation’s activity with increase in the use of the
internet, it becomes important to keep
communications like e-mail, e-commerce transactions
and data transmission secure. The reasons are very
clear, as wireless technologies comes with huge
advantage of being costless, easy to fix up and totally
mobile. The use of wireless communication has been
around since 1990’s mostly used in patented. The
obstacles to wireless communication during 90’s were
many, but these barriers are resolved in these days.
There is a huge growth to the use of wireless
technology especially in private sectors. The strong
advantages of wireless technologies it becomes
obvious that business wants to build such a
technology. It seems that there are many variety of
wireless network technologies in the market, but the
one which outstands is WLAN based on 802.11 then
we exploit the weaknesses of wireless networks and
list the various types of attacks possible on them[1].

VULNERABILITIES OF WIRELESS
Vulnerabilities are common for both wired and
wireless networks. The attacks on wireless networks
that exploit the “over air” characteristics of the
wireless signals use the eavesdropping and MITM

International Journal of Trend in Scientific Research and Development (IJTSRD) ISSN: 2456
Eavesdropping:
Eavesdropping can be described as accidently over
hearing a conversation and thus gaining important
information which is not easily available.
MITM attacks:
It is known as MAN-IN-THE-MIDDLE attack. The
MITM attack is one step beyond the Eavesdropping
attack[2]. This is an attack where the person secretly
relays and possibly alters the communication between
two parties who believe they are directly
communicates with each other.
In addition there is the possibility to acquire
unauthorized wireless access from a wireless service
point. The techniques that can be used are as follows:
Rogue Access Points
Rogue Clients
Open Access Points
WEP Key Attacks
Jamming
High Gain Antennas
Rogue Access Points:
A Rogue Access Points that has been installed on a
secure network without explicit authorization from a
local network administrator, whether added by a
employee or by an attacker.
Rogue Clients:
Enough client is a client that doesn’t belong to your
company but it is operating on your network anyway.
Open Access Point:
An Access Point is a device such as a wireless
that permits wireless devices to connect to a network.
WEP Key Attacks:
WIRED EQIVALENT PRIVACY is a security
algorithm for IEEE 802.11 wireless network
Jamming:
Jamming attacks are saviour denial -
attacks against wireless median
High Gain Antennas:
A High Gain Antenna is an antenna with a narrow
radio beam that is used to increase signal strength.

SECURITY FEARURES OF WLAN’s
The major security services for IEEE802.11 are
provided by wired equivalent privacy protocol. As per
the IEEE standards there are three basic security
features described for wireless networks. They are
Authentication
Confidentiality
Integrity.
Authentication:
A primary goal of WEP (
PRIVACY) was to provide a security service to check
the ID of communicative clients stations. This gives
access control to the network by avoiding access to
the client station that cannot authenticate
Confidentiality:
Confidentiality, or Privacy, was a second goal of
WEP the intent was to prevent information
compromise from causal eavesdropping.
Integrity:
Another goal of WEP was a security service created
to ensure that messages are not mod
wireless clients and access the point in an active
attack.
THE RISKS OF WIRELESS SECURITY IN AN
ENTERPRISE:
For an enterprise there is lot more than just protecting
the network from various attacks. There are different
measures enterprise can take, in order to secure their
network and the most important one is to keep their
wireless access points as safe as possible. The
Important reason to keep access points safe is that the
attackers do not require specific packing tools as the
system itself finds the network when it comes in the
range. One of the major risks for an enterprise from
their own naïve employees the can contact company
databases from a browser and they do the same when
the want to work at home. The attackers can take
advantages of this and instead of breaking into the
security system they would observer the activities of
employees and given a chance would get enough
knowledge that they can then trick themselves as
sincere uses of the enterprise.
Conclusion:
Wireless network security faces a number of hurdles
and efforts are being put on, but are relatively new
and thus not fully developed. Since wireless
technology has huge market but has become almost
inexpensive. It is gaining popularity in all sorts of
business. These strength of the system security is
always countered by its weakest component. So the
