So that we can secure our wireless network, we need to choose a form of encryption, ranging from WEP, which is the weakest, to WPA2—CCMP, which is the strongest. Let's look at each of these in turn:
- Wired Equivalent Privacy (WEP): WEP is the weakest form of wireless security, with a 40-bit key that is very easy to crack.
- Wi-Fi Protected Access (WPA): WPA replaced WEP as it uses the Temporal Key Integrity Protocol (TKIP), which was designed to be more secure than WEP. WPA is backward compatible with WEP. TKIP is backward compatible with legacy wireless encryption.
- Wi-Fi Protected Access version 2 (WPA2): WPA2 is much stronger than WPA and there are two main versions—one for the home user and the other for the corporate:
- WPA2-Pre-Shared Key (WPA2–PSK): WPA2-PSK was introduced for the home user who does not have an enterprise setup...
