Companies should always have a firewall between the public network and their internal system to prevent unauthorized traffic. But without overall good security, problems are more likely to grow serious over time. Ann Devlin, a reporter, discusses Internet fraud with Susan Grant, an executive from the National Fraud Information Center. Grant talks about some of the top ten frauds that occur over the Net. Purchasing of goods for normal use from chatrooms or email is a bad idea.
People send money in and recieve no goods in return.
To prevent this you should try to negotiate partial payments before buying the goods in full. Grant also discussed pyramids which are multi-level marketing schemes which try to recruit people to pay some type of fee to join a program. In return, you are supposed to get incentives like free calling cards. They look legal and attractive, but they are bogus. Grant also warns to beware of franchises promotting over the web, wanting you to invest in something like an ATM machine.
