This is a new security book from MSPress that focuses on security testing. I read some of the chapters a few weeks ago, and it's wonderful to add a testing perspective to the world of security. A great deal has been written about security and code quality, but virtually nothing about security testing, and certainly nothing as complete as this book; the authors, Bryan Jeffries, Lawrence Landauer and Tom Gallagher have done a wonderful job.
Chapter Listing:
Appendix A: Tools of the Trade
Appendix B: Security Test Case Cheat Sheet
