Wireless Network security is a process of
implementing security on a wireless network. It protects a wireless network
from unathorized networks. The most used standards of wireless security are Wired
Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA) and Wi-Fi Protected
Access II (WPA2). Dangers and motives of attack can be numerous, espionage by competitors,
offensive worker’s attacks, pirate software etc. Around 25% of networks do not
have any kind of security

 

WEP

WEP is intentend to protect privacy and it is the
most used protocol for the purpose of security. It is not strong security
sandard, and usually it can be cracked in a short time. So, WEP is an algorithm
for secure communications  through IEEE
802.11 wireless networks. Wireless networks uses radio waves fo transfering
data. Usually it is used in 64-bit and 128-bit variants and gives a false sense
of security. In 1997, when WEP occured, the idea was to secure wireless network
as wired network is secured. But in 2004, WAP is replaced the WEP, because
WEP’s weakness. Few minutes is enough to defend protection.

 

WPA

WPA is an algorithm for secure
communications  through IEEE 802.11
wireless networks. In this protocol encription and user authentication is
improved. Fore authentication they used EAP. WPA is a temporary algorithm which
sould be replaced when the work on 802.11 i is finished. The first improved
version of WPA is WPA2. It does not represent secure standard, because of
including only one secure protocol (TKIP). Combinations of WPA and TKIP is not
the best solution but provides satisfactory security.

 

WPA2

WPA2 implements the latest security standard and
it includes two standards: TKIP and CCMP. If you use TKIP, it does not matter
whether your device is WPA or WPA2. The best option for wireless network
security is CCMP security protocol and is only available on WPA2 devices. WPA2-AES
requires much more calculation, so older routers may not have the power
