So you think you’ve got world-class security and a hardened site and systems? But do you really? Just because no one has penetrated your systems yet doesn’t mean they are secure nor does it mean you should rest on your laurels. If you are serious about security you need to be constantly updating, refining and most importantly testing your security and hardened systems.

Outer layer security consists of what is best described as the crust of your system. These are your system s network connections ports or anything else that connects your systems to an intranet the Internet or other systems. The application security layer consists of the security of the applications running on your system. In each chapter where we discuss hardening a particular application we provide methods and tools to help you test that particular .
