Hi,

Its not really clear what you are asking.

The pessimist in me says that you have been set an essay question and you have decided to post it on a security forum to see what info you can gather around it. If that is the case then i've got to say you have been rather lazy constructing the post. On line security is an immense topic, i have heard people reffering to it as an onion, every time you peel back a layer you find another one. Members will probably be happy to help you with your research and you will probably get some good pointers and links, but you must ask questions that will get meaningful answers.

Think about what you know about online security, what you are trying to prove or disprove about the origional statement and ask specific questions, ie
How do websites protect data?
How is data encrypted online?
etc

I have always found the people on this forum extremely helpful
IF YOU ASK THE RIGHT QUESTIONS.

Matt
