Interview: IronPort's Scott Weiss: Page 3 of 5

I don't see an end in sight, unfortunately. Somebody asked me what the top exploits we'll see in 2007 would be. My answer was, "We have no idea." No one has any idea.

The antispam market will continue to consolidate because not that many people can keep up with the advanced techniques spammers are exploring. They can afford to bankroll hackers to put together new and innovative things we have to combat.

IronPort claims its reputation filtering stops 80 percent of spam without the need for scanning. Are spammers learning to thwart reputation filtering?

One way is through the bots. What I have seen--this is an outcrop of reputation filtering--is that people need to police their own networks. In many corporations we turn on spam scanning outbound, and they are shocked that their Fortune 500 company is a spammer. One reason is employees get infected with spyware and then have a spam-sending zombie coming out of the network.
