Chapter 7: Cryptography - Internet Security

The very first sentence of this section of the study guide is extremely important. The Web is not the Internet. The Web basically runs on the Internet. I have a pretty good understanding of how HTTP works, and that it is stateless by design. It is up to the web developer to handle data persistence. Data can be persisted in one use case, in one session, using cookies, or using a database. HTTP is more secure when running over Secure Sockets Layer. The reason the exchange of credit card information is secure is because of Secure Electronic Transaction technology. It is also to point out the difference between Secure HTTP and HTTP Secure. The first protects each message sent from computer to computer, where the latter protects the channel in which the messages are sent.
