INTRODUCTION

INTRODUCTION

Computers and the internet are wonderful modern phenomena that we just can’t do without. We are becoming dependent on them in every aspect of our lives: for work, for play, for shopping, for banking, for communicating, for learning. Whatever we do with them, and however they can benefit our daily lives, there is one unfortunate consequence that we cannot escape. They are not secure.

Communications over the internet are not secure. Emails are not confidential. They pass through many computers before reaching their destination. Internet shopping is not secure. Our credit card numbers are transmitted around the world and stored on company computers directly connected to the internet where they can become an attractive target to criminal hackers. Likewise, internet banking is not secure. If someone guesses or obtains an account’s password, the account details become visible and rogue transactions become possible.
