Chris Rouland, director of ISS's research and development team, known as X-Force, maintains that the company did the right thing when it released an advisory on the issue and included a patch as well. "We are competing with the 10 million hackers out there, who are trying to break in to Web servers," he said. "The hackers were the real ones that were ticked off that we released the advisory. That's one less exploit that they could use."
