Dealing with viruses, spyware, PC theft and other computer-related
crimes costs U.S. businesses a staggering $67.2 billion a year,
according to the FBI.

The FBI calculated the price tag by extrapolating results from a survey
of 2,066 organizations. The survey, released Thursday, found that 1,324
respondents, or 64 percent, suffered a financial loss from computer
security incidents over a 12-month period.

The average cost per company was more than $24,000, with the total cost reaching $32 million for those surveyed.

Often survey results can be skewed, because poll respondents
are more likely to answer when they have experienced a problem. So,
when extrapolating the survey results to estimate the national cost,
the FBI reduced the estimated number of affected organizations from 64
percent to a more conservative 20 percent.

"This would be 2.8 million U.S. organizations experiencing at least one computer security incident," according to the 2005 FBI Computer Crime Survey. "With each of these 2.8 million organizations incurring a $24,000 average loss, this would total $67.2 billion per year."

By comparison, telecommunication fraud losses are about only $1
billion a year, according to the U.S. Secret Service. Also, the overall
cost to Americans of identity fraud reached $52.6 billion in 2004, according to Javelin Strategy & Research.

Other surveys have attempted to put a dollar amount on
cybersecurity damages in the past, but the FBI believes its estimate is
the most accurate because of the large number of respondents, said
Bruce Verduyn, the special agent who managed the survey project.

"The data set is three or four times larger than in past
surveys," he said. "It is obviously a staggering number, but that is
the reality of what we see."

Responding to worms, viruses and Trojan
horses was most costly, followed by computer theft,
financial fraud and network intrusion, according to the survey.
Respondents spent nearly $12 million to deal with virus-type incidents,
$3.2 million on theft, $2.8 million on financial fraud and $2.7 million
on network intrusions.

These figures do not include much of the staff, technology,
time and software employed to prevent security incidents, Verduyn said.
Also, losses to individuals who are victims of computer crime or
victims in other countries are not included, he said.

The FBI’s next fiscal year, for which budgets must be reviewed
and approved, begins Oct. 1. Protecting the U.S. against high
technology crimes is third on the agency’s list of priorities.

Defenses in place
Survey respondents use a variety
of security products for protection. Antivirus software is almost
universally used, with 98.2 percent of respondents stating they use it.
Firewalls follow in second place, with 90.7 percent, and anti-spyware
and antispam are each used by about three-quarters of respondents,
according to the survey.

The results mean that close to one in 10 organizations does
not have a hardware or software firewall. Or perhaps they don’t know
they have one–the Windows Firewall in Windows XP, for example. "Some
are very small businesses that should have that technology, but they
don’t," Verduyn explained.

Biometrics and smart cards–both
relatively new security technologies–were used only by 4 percent and 7
percent of survey respondents, respectively. Intrusion prevention or
detection systems were used by 23 percent and VPNs, or virtual private
networks, by 46 percent.

Organizations were attacked despite use of security products, with
nine out of 10 respondents saying they experienced a security incident.
In fact, the most common attacks aligned with the most commonly used
defenses. Computer viruses, worms or Trojan horses plagued 84 percent
of respondents, 80 percent reported spyware trouble, and 32.9 percent
said attackers were probing their systems using network port scans.

Not all threats came from outside the organization. More than
44 percent of the survey respondents reported intrusions from within
the company. "Companies may be unaware of the internal potential for
computer security incidents," Verduyn said. He recommends applying
policies and procedures to thwart attacks from the inside.

The FBI surveyed companies in Iowa, Nebraska, New York and
Companies older than three years, with more than five employees and
with more than $1 million in revenue were asked to participate. Survey
participants were asked to provide their responses by the end of July
2005, with their answers covering the previous 12-month period.
