Denial-of-service (DOS) attacks have emerged as the type of computer-security incident that costs companies the most money, supplanting the top risk for the previous five years--theft of proprietary data--for the first time. That's one statistic from the ninth annual 2004 CSI/FBI Computer Crime and Security Survey. The survey also found that overall dollar losses have diminished dramatically from a year before, from more than $200 million to less than $150 million. Despite the reduction, the report suggests that DOS attacks have become an increasingly common threat because they are often entwined with viruses.
