Cost of computer attacks down, says survey by CSI, FBI

A new survey has found that the cost of computer and network-based attacks is dropping.

While the cost of fending off hackers appears to be dropping for U.S. companies, attacks that involved unauthorized access to information are becoming much more costly, according a survey published Thursday by the Computer Security Institute and the U.S. Federal Bureau of Investigation.

The survey, which included about 700 respondents from government and a variety of industries, found that the average losses related to computer attacks dropped by 61 percent in 2004. On average, companies reported that computer and network attacks cost them US$204,000 last year, down from an average of US$526,000 in 2003. The report did not explain how specific factors, such as loss of employee productivity or security consultant fees, contributed to these costs.

This marks the fourth consecutive year that this number has declined, said Robert Richardson, editorial director of the Computer Security Institute (CSI) and a co-author of the report.

Part of the reason for the drop is the fact that companies have simply become better at protecting themselves, Richardson said. "For your run-of-the mill virus, your average organization has that under control," he said. "There's a very fast reaction on the part of antivirus vendors and there are automated pathways to update the virus data on enterprise networks."

However, the cost of information theft jumped considerably in 2004. "To some degree, the heat of hacker activity has moved to identity theft," Richardson said.

The survey found that the average net loss attributable to unauthorized information access jumped from more than US$51,000 in 2003 to more than US$300,000 last year. Attacks that resulted in the theft of proprietary information cost companies more than US$355,000 on average in 2004, up from US$169,000 the previous year.

CSI's survey was done in conjunction with the San Francisco division of the Federal Bureau of Investigation's Computer Intrusion Squad. It canvassed about 700 CSI members in a wide variety of industries and government organizations. CSI is a San Francisco-based association of computer and network security professionals.

Given the demographics of the survey's participants, it's unsurprising that they're suffering less damage from attacks. "We ask people who care about security," Richardson said. "They care enough [about security] to be members of a professional organization, so my hunch is they're actually trying to get better at security."
