Top flight security (Chapter 18)

The World Wide Web is a gift and a curse. A gift because it offers us a endless window of knowledge, on the other hand that "free" knowledge comes at a high price and risk. Everytime you connect to a network, you run the risk of exposing your computer to cyber attacks, phising, spam and other methods of infiltration. You have to protect your computer like you would protect your own body from outside elements such as rain or snow. Being properly prepared could save you hundreds or even thousands in repair. There are many methods that are available to help protect you from the dangers of the internet. Firewalls are in place to block unwarrented material from corrupting your computer. Companies such as McAfee make software that help protect your computer from viruses and evasive files. A viru is a program that replicates by attaching itself to other programs and execute once they are ran. Keyloggers track all your keystrokes and can steal personal information, such as credit card information or social security numbers. With technology becoming more and more advanced, computer hackers are becoming more and more sophisticated. Computer techinicans have to adapat and evolve as technology grows. http://science.howstuffworks.com/life/cellular-microscopic/virus-human.htm
