It is difficult to believe that just a few years ago, no one would worry about the security of a computer or a computer network for that matter. Computer security literally meant protecting your computer from thieves. Then the landscape changed and computer after computer become interconnected forming computer networks as we know them today. As this was happening, our personal attributes were finding their way into the computer and eventually into the computer network. Computer networks multiplied, merged and grew bigger resulting into this one huge global super network that seem to include every connected computer around the globe. This global super network is actually a mosaic of thousands of smaller public and private networks of varying sizes. Because of the interconnection and interdependence of these networks, what happens in one network has the potential to affect every network and every computer in the super global network.
