There is no guaranteed way to secure communications on an access point. However, there are many techniques you can employ to make your access point a difficult target. Firmware-based APs are easy to setup but provide limited usability and security options. The flexibility gained by deploying a Linux, FreeBSD, or OpenBSD access point is somewhat offset by the more technical configuration and security requirements of a general purpose OS. Whatever option you choose, raising the bar as high as possible is very important. Now that you understand how to properly configure an access point for secure use, it is time to move farther out into the network and examine the security on the gateway.
