As I posted recently Protect Your Windows Network book by Steve Riley and Jesper M. Johansson is available for pre-ordering. Both Michael Howard and Steve Riley posted updated information about preorder (with promo code ;-)
Also yesterday I accidentially found new book by Michael, David LeBlank AND John Viega - 19 Deadly Sins of Software Security due to August 2005. It should be interesting book from authors of Writing of Secure Code and Secure Programming Cookbook.
[Update] This monday Michael Howard officially announced this book on his blog.
