The difference between WEP, WPA and WPA2
WiFi security algorithms have been through many changes and upgrades since the 1990s to become more secure and effective. Different types of wireless security protocols were developed for home wireless networks protection. The wireless security protocols are WEP, WPA, and WPA2, serving the same purpose but being different at the same time. Not only do the protocols prevent unwanted parties from connecting to your wireless network, but also wireless security protocols encrypt your private data sent over the airwaves.
No matter how protected and encrypted, wireless networks cannot keep up in safety with wired networks. The latter, at their most basic level, transmit data between two points, A and B, connected by a network cable. To send data from A to B, wireless networks broadcast it within their range in every direction to every connected device that happens to be listening.
Let's have a closer look at WEP, WPA, and WPA2 wireless security protocols.
Wired Equivalent Privacy (WEP)
WEP was developed for wireless networks and approved as a Wi-Fi security standard in September, 1999. WEP was aimed to offer the same security level as wired networks, however there are a bunch of well-known security issues in WEP, which is also easy to break and hard to configure.
