 HackNotes Web Security: Portable.Reference

"The World Wide Web brings together information,
commerce, personalities, and more. "

=======================
The applications that populate the Web reflect the desires of
persons who wish to buy, sell, trade, or just talk. Consequently,
web application security is not just about protecting
your credit card because a site uses 128-bit
encryption. It is about how the application takes your
credit card, stores it in a database, and later retrieves it
from the database. After all, if a malicious user can perform
a SQL injection attack that steals database information
using only a web browser, then the use of SSL is moot.
