Cracking of wireless networks is the defeating of security devices in Wireless local-area networks. Wireless local-area networks(WLANs) – also called Wi-Fi networks are inherently vulnerable to security lapses that wired networks Cracking is a kind of information network attack that is akin to a direct intrusion. There are two basic types of vulnerabilities associated with WLANs: those caused by poor configuration and those caused by weak encryption.
An open, unencrypted wireless network can 'sniff' or capture and record the traffic, gain unauthorized access to internal network resources as well as to the internet, and then use the information and resources to perform disruptive or illegal acts.Many laptop computers have wireless cards pre-installed. The ability to enter a network while mobile has great benefits. However, wireless networking is prone to some security. Wireless networks relatively easy to break into, and even use wireless technology to hack into wired networks.The risks to users of wireless technology have increased as the service has become more popular.As a result, it is very important that enterprises define effective wireless security policies that guard against unauthorized access to important resources.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

Security issues and Solutions
3. Introduction
Wireless LAN is a flexible communication system
implemented as an extension to a wired LAN, using
electromagnetic waves to transmit and receive data over
air, minimizing the need for wired connections.
It is a communication network that provides connectivity to
wireless devices within a limited geographic area such as
home, school, single office, building or campus.
"Wi-Fi" is the universal standard for wireless networks and is the
wireless equivalent of wired Ethernet networks.
4. Wireless LAN Technology Options
o Narrowband Technology
o Spread Spectrum Technology
o Frequency-Hopping Spread Spectrum Technology
o Direct Sequence Spread Spectrum Technology
o Infrared Technology
8. Advantages
Key drivers are mobility and
accessibility.
Increased Productivity.
Improved collaboration.
No need to reconnect to the network.
Flexible installation and scalability.
10. Is it Secure?
Someone can block the entire radio communication
channel by transmitting junk on certain frequencies and
anonymously stage a denial of service attack from your
network.
Anybody can plant viruses on our system.
The webpages can be changed.
As the number of WLAN cards grows so will the
opportunities for hackers to break into the wireless
networks.
Regardless of the technology used , WLAN security will
always be limited because users will sidestep security
features.
11. Security Issues & Solutions
War Driving
Eavesdropping
Denial of Service Attack
Rogue Access Points
12. War Driving(Access Point
Mapping)
It is the act of locating and possibly exploiting connections to
wireless local area networks while driving around a city or
elsewhere using a portable computer, smartphone or personal
digital assistant (PDA).
Wireless NIC scans for wireless access points . The computer looks
for SSID (wireless network name) which is being constantly
transmitted by the access point , letting the computers know of its
presence.
The wiredriver uses software like NetStumbler (Windows) or
Kismet (Linux) to scan the airwaves for SSIDS.
The wiredriver generally configures his/her software to log any
strong unencrypted signal using GPS receiver and connect to the
access point.
14. Solution for War Driving
o Do not broadcast your SSID.
o Change the default password.
o Encrypt your wireless connection using the encryption
schemes.
o Filter the MAC addresses that are allowed to connect to
your router.
o If you configure file sharing on your computer, make sure
it is password protected.
o Use personal firewall software.
15. Eavesdropping
In wireless sensor networks ,any wireless network residing in the transmission
range of the transmitter can potentially decode the signal when both the
transmitter and receiver are unaware of the reconnaissance.
This involves attacks against the confidentiality of the data that is being
transmitted across the network.
There are two types of eavesdropping:
I. Passive Eavesdropping: The malicious nodes detect the information by
listening to the message transmission in the wireless broadcasting medium.
II. Active Eavesdropping: The malicious nodes actively grab the information via
sending queries to transmitters by disguising themselves as friendly nodes.
16. Solution for Eavesdropping
o The best way to keep your traffic secure while on Wi-Fi
hotspots is to connect to a Virtual Private Network (VPN),
maybe to your work’s network, a server you set up at your
home, or a hosted service designed specifically for
hotspot security, such as Private Wifi or Hotspot Shield.
o We must make sure any services or sites you use while on
the hotspot are secured with SSL encryption.
o The Enterprise mode of WPA2 security (also called the
802.1X or EAP mode) requires an authentication server,
commonly called a Remote Authentication Dial In User
Service (RADIUS) which prevents users from reading each
other’s traffic.
17. Denial of Service Attack
A denial of service (DoS) attack is an assault that can
cripple or disable a WLAN. It can slow the network to
crawling speeds or actually force it to quit working.
One form of DoS attack is the "brute force" method. This
can come in one of two forms:
I. A huge flood of packets that uses up all of the network's
resources and forces it to shut down.
II. A very strong radio signal that totally dominates the
airwaves and renders access points and radio cards
useless.
18.
19. Solution for Denial of Service
Attack
This type of attack can be prevented by:
o implementing and updating firewalls.
o maintaining updated virus protection.
o ensuring strong passwords and deploy DoS detection tools,
such as AirDefense and AirMagnet in addition.
o You can protect a WLAN against DoS attacks by making the
building as resistive as possible to incoming radio signals.
20. Rogue Access Points
Rogue APs can be APs that are connected to the enterprise wired LAN
without authorization or APs that are not connected to the wired LAN
but that accept associations from clients.
Rogue APs can even be APs with a wireless card and a special
software package that makes them act as an AP.
Types of Rogue Aps based on security categories:
I. Non-malicious APs: The majority of the cases consist of someone
installing a rogue AP with the intent being not to bypass the
corporation's security policy but to deploy wireless as a convenience
or productivity enhancer.
II. Malicious Aps: the attacker sets up the AP to gain access to the wired
network or to disrupt the performance of the WLAN.
22. Prevention of Rogue APs
o Use of commercial tools like AirMagnet and AirDefence to
scan for rogue Aps periodically and verify their legitimacy.
o Using network Wireless Intrusion Prevention System (WIPS)
to watch the air or by using a host-resident Wireless IPS to
monitor client activity.
o Use of WLAN analyzer for Rogue AP detection.
o Smaller businesses on more limited budgets may prefer to
install stand-alone host WIPS programs like Sana Security
Primary Response Air Cover.
