As you set about doing business on the Web, you're going to encounter three specific types of people:
• Those who want to buy from you
• Those who want to steal from you
• Those who want to steal from those who buy from you
The paradox that every website owner faces is that you want to welcome the first type of person with open arms, but the others you'll want to try to shut out. In a traditional offline store, it's usually easy to sense where trouble is going to come from. Doing business online, however, means you lose that all important intuition.
