4.7. Making WPA2-Personal Almost As Good As WPA-Enterprise

Problem

You’re nervous about sitting there with an unsecured wireless access point, and you really want to lock it up before you do anything else. You’ve made sure that all of your wireless network interfaces support WPA2, so you’re ready to go. You don’t want to run a RADIUS authentication server, but using the same shared key for all clients doesn’t seem very secure. Isn’t there some kind of in-between option?

Solution

Yes, there is. Pyramid Linux comes with hostapd, which is a user space daemon for access point and authentication servers. This recipe will show you how to assign different pre-shared keys to your clients, instead of everyone using the same one. And, we’ll use a nice strong AES-CCMP encryption, instead of the weaker RC4-based ciphers that WPA and WEP use.
