One of the best reads of this autumn season is Keith Brown's The .NET Developer's Guide to Windows Security. If you haven't checked out this, I highly suggest you do. In fact, the .NET|BookClub is proud to have it as the Featured Book of the Month for November. Also, be on the lookout for some BIG news coming from the .NET|BookClub in the coming months.
Making applications secure has been one of the biggest priorities of Microsoft developers. However, very few books have been written for developers; most security books are aimed at administrators. Surprisingly enough given this focus on security there is not yet a leading book on .NET security. Keith Brown is one of the most respected names in the field, and has written the first book to explain how to make Windows Server 2003 applications secure using .NET. Furthermore, it is written in the format which has proven so successful for Scott Meyers and others: it is made up of 75 brief items which build on the previous ones, giving developers of all levels a complete, deep understanding of what tools are available, and how to use them to create secure applications for Windows.
