A midsize healthcare company was hit by a DoS attack that lasted three days. The attack was an exploit of Java and ActiveX vulnerabilities, a network engineer says. The company is a “tweener,” a midsize company with a network of hospitals, but so far, the company folds security into the IT department. “We were down about 90 percent of the time. And we had poor quality of service when we were up. It was a terrible time,” he says.”]
