It was supposed to provide confidentiality that was equivalent to that of wired networks (hence the name).
WEP or Wired Equivalent Privacy was released back in 1997 along with the 802.11 standard for wireless networks. Thankfully, only a handful of protocols were accepted and therefore it’s much easier to understand.
Basically, wireless security protocols came about starting in the late 90’s and have been evolving since then. I’m not going to go into too much technical detail about each of these protocols because you could easily Google them for lots of more information. Practically, you will only be able to choose from options 2 thru 6, though most routers now don’t even have an option for WEP or WPA TKIP anymore because they are insecure.
WPA2 Enterprise is way more complex to setup and is usually only done in corporate environments or in homes very technically-savvy owners. The PSK that you see with WPA2 and WPA is basically the wireless network key that you have to enter when connecting to a wireless network for the first time. It’s worth noting that WPA2 Enterprise doesn’t use pre-shared keys (PSK), but instead uses the EAP protocol and requires a backend RADIUS server for authentication using a username and password. I thought several devices would not support the highest encryption, but was surprised to find out they connected just fine. If you’re not sure if some of your devices will be able to connect using the most secure method, I suggest you enable it and then check to see if there are any issues. The more secure option you can choose, the better. It’s ranked from most secure to least secure. The following document might clarify your doubts.If you don’t care about all the technical details behind each one of these protocols and just want to know which one to select for your wireless router, then check out the list below. There are also EAP types which uses other user credentials like Certificates, SIM etc for authentcation.
#Wep vs wpa vs wpa2 which is best password#
It uses username and password for authenticating wireless clients. A RADIUS server can authenticate a wireless client with various EAP methods. It refers to the type or method of 802.1x Authentication by the RADIUS/Tacacs server. But this uses stronger encryption scheme(WPA uses RC4 and WPA2 uses AES).Īny authentication mechanism that involves a separation authentication server for authentication like ACS server is called 802.1x authentication.ĮAP stands for Extensible Authentication Protocol. This is an extension to 802.1x authentication. WPA/WPA2 -Enterprise - This uses a RADIUS Server for authentication. This uses Pre-Shared Key for authentication. WPA/WPA2-PSK - This is mainly for small offices. WPA and WPA2 are actually are of 2 types respectively. Whereas, WPA use TKIP as encryption mode which in turn uses RC4 encryption algorithm. Wi-fi appliance decided that ratification and standardization of 802.11i standards will take more time. WPA and WPA2 are all actually interim protocols that are used until the standardization of IEEE 802.11i standard.
