B. Some Tips about Internet Security

Narrator: This is Science Today. An expert on Internet security says recent hacker attacks to various sites are a passing phenomenon that will come and go over time - just like a credit card fraud. Eric Brewer, a professor of Electrical Engineering and Computer Sciences at the University of California, Berkeley, says that doesn't mean these attacks will be ignored.

Brewer: We should still be vigilant about detecting, preventing these attacks and closing the kinds of loopholes that are currently exploited and that's going to happen. But in the big picture, I think we should remind ourselves how fortunate we are that the Internet is what it is.

Narrator: Brewer has done lots of research on Internet security, including flaws in on-line credit card transactions and advises users to do what the does - only use one dedicated credit card on the Internet.

Brewer: There's two reasons I'm quite happy to do that. One is it's only one card of several I have and the more important reason is the group that's at risk here is the credit card company, not the individual. In general, you can't lose more than fifty dollars on your credit card if you're using it sincerely. They'll take the risk that it'll be safe 'cause in general, it is safe.
