Wireless security

Wireless security is the prevention of unauthorized access or damage to computers

using wireless networks. The most common types of wireless security are Wired Equivalent

Privacy (WEP) and Wi!i Protected "ccess (WP"). WEP is a notoriously weak security standard.

The password it uses can often #e cracked in a few minutes with a #asic laptop computer and widely

availa#le software tools. WEP is an old $EEE %&'. standard from * which was outdated in

'&&+ #y WP"* or Wi!i Protected "ccess. WP" was a quick alternative to improve security over 

WEP. The current standard is WP"', some hardware cannot support WP"' without firmware

upgrade or replacement. WP"' uses an encryption device that encrypts the network with a '-#it

key, the longer key length improves security over WEP.

/any laptop computers have wireless cards preinstalled. The a#ility to enter a network while mo#ile

has great #enefits. 0owever* wireless networking is prone to some security issues. 0ackers have

found wireless networks relatively easy to #reak into* and even use wireless technology to hack into

wired networks. "s a result* it is very important that enterprises define effective wireless security

 policies that guard against unauthorized access to important resources. Wireless $ntrusion Prevention

1ystems (W$P1) or Wireless $ntrusion 2etection 1ystems (W$21) are commonly used to enforce

wireless security policies.

The risks to users of wireless technology have increased as the service has #ecome more

 popular. There were relatively few dangers when wireless technology was first introduced. 0ackers

had not yet had time to latch on to the new technology* and wireless networks were not commonly

found in the work place. 0owever* there are many security risks associated with the current wireless

 protocols and encryption methods* and in the carelessness and ignorance that e3ists at the user and

corporate $T level. 0acking methods have #ecome much more sophisticated and innovative with

wireless access. 0acking has also #ecome much easier and more accessi#le with easyto

1ome organizations that have no wireless access points installed do not feel that they need to address

wireless security concerns. $n1tat /25 and /ET" 6roup have estimated that -7 of all corporate

laptop computers that were planned to #e purchased in '&&- were equipped with wireless cards.

$ssues can arise in a supposedly nonwireless organization when a wireless laptop is plugged into the

corporate network. " hacker could sit out in the parking lot and gather information from it through

laptops and8or other devices* or even #reak in through this wireless card9equipped laptop and gain
