Create ''Computer security'' tutorial teaching how to prevent attacks and vulnerabilities.

Create a written tutorial for high school students teaching the basics of computer security. Assume the reader has a very minimal knowledge of computer security, programming, networks, etc. Do not be afraid to use technical terms as long as you define them. The tutorial should be no longer than a few pages, but I am open to suggestions of how long something like this will be. Write an overview of all major computer-related security vulnerabilities and attacks (Including: Viruses, SQL injection, spoofing, phishing, etc.). Include, when possible, famous and / or interesting historic examples of where each vulnerability was exploited. Teach basic methods to protect against each of them. Include the most popular software and services used to protect against them.
