Take Control of Your Wi-Fi Security and Take Control of Your AirPort Network released: I co-wrote the former, Take Control of Your Wi-Fi Security, which offers extensive, hands-on, step-by-step coverage and detailed explanations of how to set up Wi-Fi security for home and small office networks for Mac and Windows. This is version 1.0 of this ebook ($10, downloadable, 161 pages), but it's an adaptation with extensive revision and new material of a section of The Wireless Networking Starter Kit. The book covers WEP weakness, WPA and WPA2, using 802.1X, and a host of other security issues. It's appropriate for someone setting up a small home network, but has sections devoted to networks ranging from about 5 to 50 users.
This is version 1.0 of this particular book, but it's adapted from two editions of The Wireless Networking Starter Kit, co-written by Adam Engst and myself. That book is now out of date, and that prompted us to release this part, extensively revised and with piles of new material.
Take Control of Your AirPort Network, written by yours truly, is now at version 1.2 ($10, 155 pages, downloadable), updated to cover Tiger, and re-organized from its previous release. It's targeted at Mac users who may be using AirPort equipment or other popular gear, and explains how to connect Mac OS 9, X, and Windows XP systems to AirPort networks, and how to create the most suitable network settings for a Mac.
Both books have large downloadable excerpts so you can see if you like our style, approach, and depth before purchasing.
The two books together may be purchased for $17.50. It's a delight to write ebooks because it's a simple matter to add material and release updates over time. So far, the AirPort book has had several minor and two major updates, but purchasers of the 1.0 edition have received each update at no cost.
