HOMEWORK the best solution but provides satisfactory security. WPA2

HOMEWORK 3  What are the Network security standards used themost in WiFi devices? Wireless Network security is a process ofimplementing security on a wireless network. It protects a wireless networkfrom unathorized networks.

The most used standards of wireless security are WiredEquivalent Privacy (WEP), Wi-Fi Protected Access (WPA) and Wi-Fi ProtectedAccess 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 nothave any kind of security WEPWEP is intentend to protect privacy and it is themost used protocol for the purpose of security. It is not strong securitysandard, and usually it can be cracked in a short time. So, WEP is an algorithmfor secure communications  through IEEE802.11 wireless networks.

Wireless networks uses radio waves fo transferingdata. Usually it is used in 64-bit and 128-bit variants and gives a false senseof security. In 1997, when WEP occured, the idea was to secure wireless networkas wired network is secured. But in 2004, WAP is replaced the WEP, becauseWEP’s weakness. Few minutes is enough to defend protection.

 WPAWPA is an algorithm for securecommunications  through IEEE 802.11wireless networks. In this protocol encription and user authentication isimproved. Fore authentication they used EAP. WPA is a temporary algorithm whichsould be replaced when the work on 802.11 i is finished.

The first improvedversion of WPA is WPA2. It does not represent secure standard, because ofincluding only one secure protocol (TKIP). Combinations of WPA and TKIP is notthe best solution but provides satisfactory security. WPA2WPA2 implements the latest security standard andit includes two standards: TKIP and CCMP. If you use TKIP, it does not matterwhether your device is WPA or WPA2. The best option for wireless networksecurity is CCMP security protocol and is only available on WPA2 devices.

WPA2-AESrequires much more calculation, so older routers may not have the power
